Zapier vs Make vs n8n: how each one counts your work, AI steps and self-hosting

Ricardo Machado — Fri, 30 Oct 2026 11:00:00 GMT

You want each new form submission to land in your CRM, post to a chat channel and get a reply drafted by an AI model, and three tools keep coming up: Zapier, Make and n8n. Their pricing pages use three different words for what you pay for, so the cheapest plan on the page may not be the cheapest for your workflow. All three are hosted services you rent, the model explained in What is SaaS?, and n8n can also run on your own server.

This comparison works from the vendors’ own pricing and help pages, checked in October 2026. Prices change often, so treat every figure as dated and recheck it on the linked page before you buy. For the plumbing underneath, APIs, webhooks and rate limits, see SaaS integration.

Billing units in plain terms

Think of three car parks with several barriers inside. The first charges for each barrier you pass after the entrance. The second charges for every barrier, the entrance included. The third charges once per visit, however many barriers you pass. The same drive costs very different amounts in each.

The three tools bill like that:

Zapier counts tasks. “A task is any successful action that runs in Zapier.” Triggers, filters, paths, formatter steps and failed actions do not count, and Zapier says polling checks “never use tasks.”
Make counts credits. “Every time a module in a scenario performs an action, it consumes credits.” Make’s help pages call each module run an operation: a module that processes 10 records (bundles) uses 10 operations, and a trigger uses one operation per check.
n8n counts executions. “An execution is a single run of your entire workflow.” The number of steps and the data volume do not change the count.

The plans as listed

Checked October 2026	Zapier	Make	n8n
Free	100 tasks a month, two-step Zaps, polling every 15 minutes	1,000 credits a month	Community Edition, self-hosted
Entry paid plan	Professional: $19.99 a month billed annually ($29.99 monthly), 750 tasks	Core: price not shown in the page text	Starter: €20 a month billed annually, 2,500 executions
Next plan	Team: $69.00 a month billed annually ($103.50 monthly), 2,000 tasks	Pro, Teams, Business: prices not shown	Pro: €50 a month billed annually, 10,000 executions
Self-hosting	No	No	Yes

Two notes on the table. Make’s pricing page did not show plan prices in its text when checked; it says paid allowances are “proportional to the number of credits that you purchase”, so read Make’s pricing page in your browser. n8n listed its prices in euros when checked, and your region may see another currency.

Example: one workflow on three meters

Example: a form submission starts a workflow with five actions: create a CRM contact, add a tag, post to a chat channel, ask an AI model for a reply draft and save the draft to a document. It runs 100 times a month, then 2,000 times. The trigger is instant (a webhook), each run carries one record, and Make’s trigger is assumed to use one credit per run.

Runs per month	Zapier tasks (5 actions x runs)	Make credits (1 trigger + 5 modules) x runs	n8n executions (1 per run)
100	5 x 100 = 500	6 x 100 = 600	100
2,000	5 x 2,000 = 10,000	6 x 2,000 = 12,000	2,000

Read the rows against the listed plans:

At 100 runs: Zapier’s 500 tasks fit Professional’s 750-task tier at $19.99 a month. Make’s 600 credits fit inside its free 1,000. The 100 n8n executions fit Starter’s 2,500 at €20.
At 2,000 runs: Zapier’s 10,000 tasks are 10,000 / 2,000 = 5 times Team’s entry tier, so you price a larger tier on the page. Make’s 12,000 credits need a paid allowance. The 2,000 n8n executions still fit Starter.
Add a sixth action: Zapier rises to 6 x 2,000 = 12,000 tasks, up 20%. Make rises to 7 x 2,000 = 14,000 credits. n8n stays at 2,000.

Per-step meters grow with every action you add; a per-run meter grows only with runs. Neither is cheaper in general. Short workflows that run rarely are cheap everywhere, and long workflows that run often favor the per-run count.

Polling changes Make’s number. A trigger that checks for new data every 15 minutes runs 4 x 24 x 30 = 2,880 checks in a 30-day month, and each check uses an operation even when it finds nothing. On Zapier the same polling costs no tasks.

AI steps are charged differently

Zapier: AI by Zapier is not on the Free plan. The pricing page says AI steps are charged per AI step and per tool call, with the cost depending on the model tier, and it sends you to a separate rates page. Zapier Agents is billed on its own allowance and “does not count as tasks.”
Make: the pricing page says most actions use one credit, while some features that run on Make’s AI Provider may use more. It does not list the amounts.
n8n: the pricing page counts one execution per run whatever the steps inside it do.

Whichever tool you pick, check how the AI model in your step is paid for: through the tool’s own credits, or through your own account with the model provider. That second bill does not appear on any of these pricing pages.

Self-hosting n8n: free to run, not free to own

n8n’s Community Edition is self-hosted and free, with its source on GitHub under the Sustainable Use License. That license allows use “only for your own internal business purposes or for non-commercial or personal use.” If you plan to sell hosted automation to clients, read the license before you build on it.

Self-hosting moves the bill from executions to your server and your time. Updates, backups, uptime and security patches become yours. In a hypothetical case, a $20-a-month server plus 3 hours of upkeep a month at $50 an hour costs $20 + 3 x $50 = $170 a month. That is more than n8n’s own Pro plan, so self-hosting tends to pay off for volume or data-location reasons, not to save the first subscription.

How to choose by billing shape

Your workflows	Unit that tends to fit	Check before you commit
Few, short, many different apps, no developer	Zapier tasks	Tier price at your real task count; AI step rates
Branching scenarios over lists of records	Make credits	Bundles per run and polling frequency
Long workflows, high volume, or data that must stay on your servers	n8n executions	Execution limits per plan; license terms if self-hosted

The table is about how each meter grows, not product quality. Confirm that the apps you need have connectors on the tool you pick. For how per-unit pricing compares with per-seat pricing in general, see SaaS pricing models.

Common mistakes

Comparing headline prices, not units. A $19.99 plan and a €20 plan look equal until one counts every action and the other counts whole runs. Why it happens: pricing pages lead with the price. Instead: count actions, modules and runs for your real workflow, as in the example.
Forgetting Make’s polling checks. A 15-minute trigger uses 2,880 operations a month before any data arrives. Why it happens: the trigger feels free because nothing visible happens. Instead: use instant triggers where the app offers webhooks, or poll less often.
Ignoring AI step charges. An AI step can carry a charge on top of the task or credit it uses. Why it happens: AI pricing sits on a separate rates page. Instead: price the AI step separately, including any bill from the model provider.
Self-hosting to save money without counting your time. Three hours of upkeep a month can cost more than a hosted plan. Why it happens: the software is free to download. Instead: self-host for volume, control or data location, and budget the hours.

In three sentences

Zapier bills each successful action as a task, Make bills each module run as a credit, and n8n bills each whole workflow run as an execution. A five-action workflow run 2,000 times a month is 10,000 Zapier tasks, about 12,000 Make credits and 2,000 n8n executions, before any AI step charges. Price your own workflow in all three units on the vendors’ current pages, and count your own hours before you decide to self-host n8n.

AI agent examples: seven real use cases in support, sales, engineering and finance

Ricardo Machado — Wed, 28 Oct 2026 11:00:00 GMT

You keep hearing that AI agents will take over work in your company, but the examples you find are demos or vague promises. You need concrete cases: what the agent does, where a person still steps in, and who said so, and when. Then you can judge which of your own tasks fit.

An AI agent is software that uses a language model to pursue a goal by taking steps, such as looking up data, calling another app or drafting a reply. Most agents reach companies inside SaaS products they already pay for, a delivery model explained in What is SaaS?. The examples below come from vendors’ own pages and announcements, each with its date.

An AI agent in plain terms

Think of a new junior assistant with a checklist and keys to a few rooms. A chatbot answers what you ask. An assistant with a goal decides the next step, opens the rooms it has keys for, and checks whether the job is done. A fixed workflow, by contrast, repeats the same steps every time, whatever it finds.

Two terms come up in every example:

Tool call: the agent’s request to another system, such as searching a help center, reading a CRM record or opening a pull request.
Human in the loop: a point where a person approves, reviews or takes over the agent’s work.

Seven examples by department

“Human role” quotes what the source says. Where the source says nothing, the table says so, and you should treat that as a question for the vendor.

Department	Agent	What it does	Human role stated by the source	Source and date
Support	Klarna AI assistant	Handled 2.3 million conversations in its first month, two-thirds of Klarna’s customer service chats, in 23 markets and more than 35 languages	Not stated in the release	Klarna press release, February 27, 2024
Support	Intercom Fin	Answers customers and completes workflows; billed at $0.99 per outcome	Handoffs to the human team count as a completed workflow	Intercom pricing, checked October 17, 2026
Sales	HubSpot prospecting agent	“Monitor buying signals and launch personalized outreach automatically”	Not stated on the page	HubSpot AI, checked October 17, 2026
Engineering	GitHub Copilot cloud agent	Researches a repository, plans changes, edits files and runs tests in a temporary cloud environment, then opens one pull request per task; sessions stop at 59 minutes	“Review and test the output before using it in production”; admins can disable it per repository	GitHub Docs, checked October 17, 2026
Finance	Ramp Policy Agent	Reviews each expense against company policy and recommends approval, rejection or review; auto-approves clearly in-policy expenses under a threshold	Controllers set what it may auto-approve and where exceptions escalate; reviewers handle “the 10-15% of transactions that actually require judgement”	Ramp blog, January 13, 2026
Finance	HubSpot revenue agent	“Collect payments faster by automating invoice follow-up and reminders”	Not stated on the page	HubSpot AI, checked October 17, 2026
Operations	Notion Agent	Completes multi-step tasks in a Notion workspace; listed on the Business plan	Not stated on the page	Notion pricing, checked October 17, 2026

What the seven have in common

A narrow task with a finish line. Resolve a conversation, approve an expense, open a pull request. None of them is “run the sales team”.

Access limited to a few systems. The GitHub agent works on one branch at a time. If a ruleset or branch protection rule is incompatible with it, GitHub blocks the agent’s access.

A defined way out. Ramp’s controllers decide where exceptions escalate. When a policy does not cover a case, the agent escalates it and flags the gap. Fin’s handoffs pass a conversation to people.

Results reported by the vendor. Klarna’s numbers are Klarna’s. Ramp says teams using its agent report “reclaiming 4-5 hours per week from manual reviews” and that more than 1,000 finance teams use it. These are claims, not independent benchmarks.

You can still learn from them. Klarna reported 2.3 million conversations as two-thirds of its chats, so the month’s total was about 2.3 million / 2 x 3 = 3.45 million. It also said resolution time fell from 11 minutes to under 2, a saving of at least 9 minutes per errand, and repeat inquiries dropped 25%. That last metric matters most, because a customer who has to ask again was not helped.

Worked example: sizing a support agent for your queue

Example: a labeled hypothetical that uses one public price. Your team handles 4,000 support conversations a month. Each costs you $6 in staff time. You test an agent billed per outcome at Intercom’s listed $0.99, and it resolves 35% of conversations.

Billed outcomes: 4,000 x 35% = 1,400. Agent cost: 1,400 x $0.99 = $1,386.
Left for people: 4,000 - 1,400 = 2,600. Staff cost: 2,600 x $6 = $15,600.
Before the agent: 4,000 x $6 = $24,000. After: $15,600 + $1,386 = $16,986.
Saving: $24,000 - $16,986 = $7,014 a month, or 29%.

Now read the outcome definition. Intercom also bills a completed handoff. Suppose 300 of the 1,400 billed outcomes were handoffs that your team then answered.

People now handle 2,600 + 300 = 2,900 conversations: 2,900 x $6 = $17,400.
Total: $17,400 + $1,386 = $18,786. Saving: $24,000 - $18,786 = $5,214, or 21.7%.

The agent still saves money, but a quarter less than the first estimate: $5,214 / $7,014 = 74%. The difference came from one clause in the definition of an outcome. Measure handoffs separately in any pilot.

Questions to ask before you deploy an agent

What is the one task, and how will you know it was done right?
Which systems can it read, and which can it change?
At what point does it hand over to a person, and who receives the handoff?
How will you sample its work each week?
What does it cost per finished task, not per action or per seat?

For how agents fit into the CRM data they read and write, see CRM SaaS. For the connections between apps that agents depend on, see SaaS integration.

Common mistakes

Using a vendor’s case study as your forecast. Klarna’s volume and Ramp’s hours describe their customers, not your queue. Why it happens: the numbers are public and specific. Instead: run a pilot on your own work and measure it.
Giving the agent more access than the task needs. An agent that can change any record can make any mistake. Why it happens: broad permissions make setup faster. Instead: start with read access plus one write action, and use controls like GitHub’s per-repository switch.
No escalation path. The agent meets a case nobody planned for and guesses. Why it happens: pilots test the happy path. Instead: set thresholds for automatic action, as Ramp’s controllers do, and route everything else to a named person.
Measuring deflection instead of resolution. A customer who gives up is counted as handled. Why it happens: deflection is the number the dashboard shows. Instead: track repeat contacts, as Klarna did, and read a sample of closed conversations every week.

In three sentences

The AI agents with public track records each do one narrow task, such as resolving a chat or reviewing an expense, and hand over to a person at a defined point. Their published results are vendor claims, and in the example a support agent saves $7,014 a month on paper but $5,214 once billed handoffs are counted. Before you deploy one, define the task, limit its access, name who receives escalations and measure resolution, not deflection.

Workflow automation tools: how no-code automation works, from triggers to AI steps

Ricardo Machado — Tue, 27 Oct 2026 11:00:00 GMT

Every day someone on your team copies a form entry into the help desk, pastes a summary into chat and sends the same reply by hand. You have heard that tools such as Zapier, Make and n8n can do this, and you want to know how a flow is built and what it costs to run. Workflow automation tools connect your SaaS apps with rules you set: when something happens in one app, they carry out steps in others, without code.

Knowing the parts of a flow tells you what to build, what can break and how the tool will bill you. This guide covers triggers, actions, filters, AI steps and error handling, then counts the billable units of one flow, step by step. For the basics of the apps being connected, see What is SaaS?.

Workflow automation in plain terms

Think of a mailroom clerk with a card of rules on the desk. When a letter arrives, the clerk reads the envelope. Bills go to finance, complaints go to the manager with a copy to the log, and junk goes in the bin. The clerk never decides what the rules should be; the clerk follows the card, every time, all day.

A workflow automation tool is that clerk for your apps. The letter arriving is the trigger. Sorting is a filter or a branch. Each delivery is an action. The card of rules is the flow you build.

The rules are fixed in advance. Anthropic’s Building effective agents (December 19, 2024) calls these “predefined code paths”, and that is what separates a workflow from an AI agent, which picks its own next step.

The building blocks

Trigger. The event that starts a run: a new form entry, a new row, an incoming email, a schedule.
Actions. What happens in other apps: create a ticket, add a CRM contact, send a message.
Filters and branches. Conditions that stop a run or send it down one of several paths.
Data mapping. Choosing which field from one step fills which field in the next, and formatting dates, names and amounts on the way.
AI steps. A language model call inside the flow. The three common uses are classify (which category is this?), extract (pull the order number out of an email) and draft (write a first reply).
Error handling. What happens when a step fails: retry, take an error path, alert a person.

AI steps change one thing about a flow: their output is not guaranteed. A classifier can put a refund request in the wrong bucket. Keep a person in front of anything that leaves the company. Microsoft’s AI agent shared responsibility model recommends human approval for actions such as “external sends”, and the same rule fits AI steps in a workflow.

How tools count what you pay for

Each tool bills a different unit, which is why the same flow can cost very different amounts. Checked on October 17, 2026:

Tool	Billing unit	What counts	Source
Zapier	Task	Each successful action; triggers, filters and paths do not count; AI step usage depends on the model tier	Zapier help, updated August 21, 2026
Make	Credit	By default one operation equals one credit for fixed-usage modules; AI modules can also consume credits by tokens	Make help, credits
n8n	Execution	“a single run of your entire workflow”, whatever the number of steps	n8n pricing

n8n’s cloud plans listed 2,500 executions a month on Starter at 20 euros a month and 10,000 on Pro at 50 euros, billed annually. A full price comparison of the three tools belongs in a separate guide; the point here is the unit.

One flow, counted step by step

Example: a hypothetical support intake flow with 600 form submissions a month.

The flow:

Trigger: new form submission.
Filter: stop entries that look like spam.
AI step: classify the request as billing, technical or urgent.
Action: create a ticket in the help desk.
Branch: if urgent, post a message to the on-call chat channel.
Action: send an acknowledgement email to the customer.

Assumptions: the filter stops 20% of entries, 15% of the remaining entries are urgent, and the AI step uses 1 task at the chosen model tier (check the tier you pick, since Zapier says usage depends on it).

Entries that pass the filter: 600 x 80% = 480.
Tasks per passing entry without the branch: AI step + ticket + email = 3.
Base tasks: 480 x 3 = 1,440.
Urgent entries: 480 x 15% = 72, each adding 1 chat message = 72 tasks.
Spam entries: 120 runs, using 0 tasks, because the trigger and the filter do not count.
Total in Zapier’s unit: 1,440 + 72 = 1,512 tasks a month.

In n8n’s unit, every run of the workflow is one execution. All 600 submissions start a run, so the flow uses 600 executions a month, whether a run stops at the filter or goes all the way.

Same flow, two very different numbers: 1,512 in one tool, 600 in another. Neither is cheaper in general. Per-step units reward short flows; per-run units reward long ones.

Error handling that holds up

A flow that works on day one breaks later, usually because something outside it changed: a field renamed, a token expired, an app down for an hour. Build for that from the start:

Retries for temporary failures, with a limit.
An error path that records the failed entry and its data, so nothing is lost silently.
An alert to a named person, not a shared inbox nobody reads.
A weekly check of failed runs, even when no alert fired.

Error paths can cost money too. Zapier counts successful actions inside error handler paths as tasks, so include them in your estimate.

For how apps connect underneath (APIs, OAuth and webhooks), see SaaS integration. Flows that write to your CRM are covered in CRM SaaS, and rolling a new tool out to a team in SaaS implementation.

Common mistakes

Estimating cost from runs instead of the tool’s unit. A six-step flow can bill three units per run in one tool and one in another. Why it happens: “runs per month” is the number people know. Instead: count units per run for each path, then multiply by volume, as in the example.
Letting an AI step send messages unreviewed. A misclassified complaint can get the wrong reply. Why it happens: the demo worked on the first ten entries. Instead: route AI drafts to a person for approval, or limit them to internal steps.
No error path. Failed runs disappear and nobody notices until a customer chases. Why it happens: flows are built for the happy path. Instead: add an error path, an alert to a named owner and a weekly review.
Automating a process nobody has written down. The flow copies today’s confusion faster. Why it happens: the tool makes building quick. Instead: write the steps and the exceptions on one page first, then build.

In three sentences

Workflow automation tools run fixed rules across your SaaS apps: a trigger starts a run, filters and branches route it, actions do the work and AI steps can classify, extract or draft. Each tool bills a different unit, so the same 600-submission flow costs 1,512 tasks in Zapier’s unit and 600 executions in n8n’s. Count units per path before you buy, keep a person in front of AI output that leaves the company, and give every flow an error path with a named owner.

What is agentic AI? AI agents explained without the hype

Ricardo Machado — Sun, 25 Oct 2026 11:00:00 GMT

Every software launch now mentions “agents”, and someone on your team has asked whether you need one. You need a definition you can hold a product demo against, not a slogan. Agentic AI is software in which a language model decides its own next step and uses tools to act, in a loop, until a goal is met or a limit stops it.

That definition matters because it tells you what to test, what can go wrong and who is accountable. This guide covers the agent loop, the difference between an agent, a chatbot and a workflow, why errors compound over many steps, and what stays your responsibility. For the basics of software delivered as a service, see What is SaaS?.

Agentic AI in plain terms

Think of three kinds of help in an office. A receptionist answers questions when asked. A clerk follows a written checklist, step by step, the same way every time. A trusted assistant gets a goal, such as “get the team to the conference for under $1,500 each”. The assistant works out the steps alone: checks flights, compares hotels, books, and comes back when something blocks the plan.

The receptionist is a chatbot. The clerk is a workflow. The assistant is an agent.

Anthropic, which builds language models, draws the line between the last two in Building effective agents (December 19, 2024). Workflows are “systems where LLMs and tools are orchestrated through predefined code paths”. Agents are “systems where LLMs dynamically direct their own processes and tool usage”. An LLM (large language model) is the model that reads and writes text.

Microsoft’s AI agent shared responsibility model (updated August 26, 2026) adds what makes an agent different from a model that only answers. An agent “invokes tools, calls APIs, writes data, and triggers workflows without a human approving each step”. It also plans, keeps memory and holds an identity of its own when it signs in to other systems.

The agent loop

Strip away the branding and an agent runs one loop:

Goal. A person or a system states what should be true at the end.
Plan. The model breaks the goal into a next step.
Tool call. The model calls a tool: a search, an API, a database query, a script.
Check. The model reads the result and decides whether it moved closer to the goal.
Repeat or stop. It loops back to step 2, or stops because the goal is met, a limit is hit or it needs a human.

Anthropic’s guidance puts weight on step 4. An agent should get “ground truth” from its environment at each step, such as a tool result or the output of code it ran. It can pause for human feedback at checkpoints or when it hits a blocker. Stopping conditions, such as a maximum number of iterations, keep the loop under control.

The tools are what turn text into action. A model that can only write a reply cannot change anything. A model connected to your CRM, your email and your billing system can.

Agent, chatbot or workflow

The three are often sold under the same label. This table separates them by what each one does, not by what it is called.

Question	Chatbot	Workflow with AI steps	Agent
Who decides the next step?	The person asking	The designer, in advance	The model, at run time
Can it change data in other systems?	No, a person acts on the answer	Yes, along fixed paths	Yes, through any tool it has been given
Number of steps	One reply per question	Fixed	Varies per run
Cost per run	Predictable	Predictable	Varies with the number of loops
Typical failure	A wrong answer a person can spot	A broken path or bad input	A wrong action, repeated or chained
Fits best	Questions and drafts	Repeatable tasks with known steps	Open-ended tasks where the steps cannot be listed in advance

Read the last row first. If you can write the steps down, a workflow is cheaper to run and easier to test. Anthropic recommends “finding the simplest solution possible, and only increasing complexity when needed”. It adds that for many applications, “optimizing single LLM calls with retrieval and in-context examples is usually enough”.

Why errors compound

Anthropic states the trade-off: “The autonomous nature of agents means higher costs, and the potential for compounding errors.” The arithmetic shows why.

Example: a hypothetical agent that gets each step right 95% of the time, with steps treated as independent.

2 steps: 0.95 x 0.95 = 0.9025, so 90.3% of runs finish without an error.
5 steps: 0.95^5 = 0.774, so 77.4%.
10 steps: 0.95^10 = 0.599, so 59.9%.
20 steps: 0.95^20 = 0.358, so 35.8%.

A step that looks reliable on its own fails four runs in ten once it is chained ten times.

Now add a working check. Suppose the agent catches a bad step and retries it once, and the retry also succeeds 95% of the time. A step then fails only if both attempts fail: 0.05 x 0.05 = 0.0025. Each step succeeds 1 - 0.0025 = 0.9975 of the time. Over 10 steps: 0.9975^10 = 0.975, so 97.5% of runs finish cleanly.

The model did not get smarter between the two calculations. The check did the work. That is why step 4 of the loop, and the “ground truth” behind it, decides whether an agent is usable.

What stays your responsibility

Microsoft’s agent model lists what you keep whatever product you use. You own your data and the agent’s identity, including the scope of every credential it holds. You decide which actions it may take and which need a human, and you answer for what it does. It recommends human approval for “high-impact, irreversible, or sensitive actions” such as writes, deletes, payments, production changes and external sends.

The same document names the risks that are new with agents. Prompt injection, where text in a web page, document or email hijacks the agent, can now trigger actions instead of a bad answer. “Excessive agency” means the agent has more tools or permissions than the task needs. Its rule of thumb fits on one line: “Autonomy never reduces accountability.”

In practice, an agent that reads your support inbox and can issue refunds is a support tool and a payment tool at once. Treat its permissions the way you would treat a new employee’s on day one.

If you connect an agent to your SaaS apps, the plumbing is the same as any integration: APIs, OAuth grants and webhooks, covered in SaaS integration. Rolling it out follows the same discipline as any new system, see SaaS implementation.

Common mistakes

Calling every chatbot an agent. A system that only replies cannot act, so it carries different risks and costs. Why it happens: vendors use “agent” as a marketing label. Instead: ask which tools it can call and whether it decides its own next step.
Choosing an agent for a task with fixed steps. You pay for variable loops and accept compounding errors where a workflow would do. Why it happens: agents are what is being launched. Instead: write the steps down; if you can, build a workflow first.
Giving the agent a broad standing identity. One admin-level token lets a single injected instruction reach everything. Why it happens: broad access makes the demo work. Instead: grant each tool only the permissions its task needs, and require approval for writes, payments and external sends.
Running the loop with no limits. Without a step, time or cost ceiling, a confused agent keeps calling tools. Why it happens: limits feel like they block the goal. Instead: set a maximum number of iterations and a budget per run, and log every tool call.

Agentic AI is software in which a language model picks its own next step and uses tools to act, looping until it finishes or a limit stops it. A chatbot only answers and a workflow follows steps fixed in advance, so use an agent only when the steps cannot be written down. Errors compound across steps (95% per step becomes 59.9% over ten), so the check, tight permissions, human approval for risky actions and hard limits decide whether an agent is safe to run.
