AI agent vs workflow automation comes down to who decides the steps. Workflow automation, such as a Zap, runs a fixed trigger and actions between apps that have an integration. An AI agent takes the outcome you describe and works out the steps. Use automation for fixed app-to-app wiring, and an agent when the job crosses tools nothing connects to.
What is the difference between an AI agent and workflow automation?
Workflow automation follows a recipe; an AI agent follows a goal. In Zapier's terms, a Zap consists of a trigger and one or more actions: a new spreadsheet row starts it, and the actions you mapped run in order. Zapier describes these steps as following fixed rules and running the same way every time. For identical runs, that predictability is the point.
An AI agent starts at the other end. You say what you want finished, such as "download this month's invoices from the supplier portal and file them", and the agent decides which tools to open and in what order. That lets it handle a step nobody scripted, which is also the risk, unless the agent is built to stop and show you.
The labels have blurred: Zapier now sells agents too, and offers modes where AI handles one step or plans the whole run. What matters is what the software can reach, and what it does before an action you cannot take back.
How is Kaer different from a Zapier-style automation?
As a Zapier alternative, Kaer is made to measure. You describe the outcome in plain words, and Kaer picks one of three routes for each part of the job, then shows you what it did.
A connector where one exists
Where Kaer has built a direct connection, it uses it: mail, calendar, files and spreadsheets, team chat, code and issue tracking, some in beta. That list is short next to Zapier's catalogue; the integrations directory shows which tools connect directly.
Its own browser for every tool you log into
Everywhere else, Kaer signs in and works the web app in its own sandboxed browser, on a separate machine kept apart from your computer, the way a person on your team would: supplier portals, booking systems, the old back-office tool. The short rule: if you can log in, Kaer can work it, within the limits below.
The missing tool, built
When no app fits the job, Kaer builds a small one. Describe the tracker your team keeps rebuilding in a spreadsheet, and Software Builder shows you a plan before it writes code and a working preview before anything goes live. Publishing is your button. If you have developers, it opens a pull request instead, and nothing merges until someone presses Merge. The case is made in why to build the tool instead of another workaround.
A recurring workflow uses the same routes: described once, run on a schedule or when an email arrives, every step visible before you turn it on.
Zapier vs AI agent vs Kaer: how do they compare?
A Zap wins on predictability, a general agent on flexibility, and Kaer on reach into the tools you log into, with gates on by default. The middle column describes agents as a category, so it is general.
| Workflow automation (a Zap) | AI agent, in general | Kaer | |
|---|---|---|---|
| How you set it up | Pick a trigger, then map each action field by field. | Describe the goal; the agent plans the steps. | Describe the outcome in plain words; Kaer works out the steps and shows them. |
| What it reaches | Zapier's catalogue of 9,000+ apps, plus webhooks. | The tools it is connected to; some also browse the web. | Direct connectors, its own browser for any tool you log into, and tools it builds. |
| When something changes | Each step runs the same way until someone edits the Zap. | It adapts its plan: flexible, harder to predict. | Change the brief in plain words. A failed step stops the run and tells you; anything unclear, it asks. |
| Who approves | Whoever builds the Zap adds a Human in the Loop step where they want one. | Depends on the product and its settings. | Sending, paying, publishing, cancelling and merging wait for a person by default. The agent cannot remove a gate. |
| How it is priced | By tasks: each successful action counts, triggers do not. | Varies. Zapier Agents, for example, meter activities. | By the work, from one prepaid balance, with no per-seat pricing. |

Can you automate tasks without an integration?
Yes, if the tool works in an ordinary browser. Kaer opens it in its own browser, signs in with a login you have saved, and does the steps you asked for while you watch in a live pane beside the chat. This is the work app-to-app automation cannot reach. The limits are specific:
- When a site asks for a password, a one-time code or card details, Kaer stops. You click Take over, type it yourself, and hand back. Kaer can't see or keep your password.
- Kaer does not solve or get around security checks. If a site blocks automated browsers outright, it tells you and offers you control.
- Systems behind a VPN, or with an unusual sign-in, need a conversation first. The browser comes with paid plans.
The guide on how to work a website with no integration walks through one job step by step, and automating the tools you log into covers which jobs suit the browser route.
What is agentic automation, and why does it move the bottleneck?
Agentic automation gives software a goal instead of a recipe. Once software can choose its own steps, the limiting question moves from whether two apps can talk to whether one job can be finished end to end, accountably.
For popular apps, the first question is largely answered: Zapier alone lists 9,000+ apps. What still stops a job is the step after the last integration. Take a supplier invoice. The email arrives in a connected inbox, the invoice sits behind a login on the supplier's portal, filing it is a connected step again, and paying it should never happen unseen. A Zap carries the connected steps and hands the portal and the payment back to a person.
End to end means one agent takes all four. Kaer signs in to the portal with the login you saved, finds the invoice, files the PDF in your Drive, and stops at the payment with the amount in front of you. That is the worked example on the integrations page.
Accountably is the harder half, and any agent, ours included, should be asked for specifics:
- Gates are on by default. Sending, paying, publishing, cancelling and merging wait for a person. You can add to that list; the agent cannot remove anything from it.
- A browser is not a loophole. A payment in Kaer's browser stops for approval exactly like one through a connector.
- Every step is on the record. Each task keeps the steps taken and tools used; every approval is timestamped and attributable.
- It does not work around you. Revoke a connection mid-job and the job stops rather than finding another way round. A failed workflow step stops and tells you.
- Spend stops at zero. When the prepaid balance runs out, work stops, and nothing is billed afterwards.
Zapier can pause for a person too: its Human in the Loop tool holds a Zap at a chosen step for review. The difference is the default. In a Zap, review is a step someone has to remember to add. In Kaer, the consequential steps wait unless you have chosen to let a specific routine email go, and payments stay gated regardless. The full list is in what Kaer will not do without you.
Ask any agent what happens at the step you cannot take back, and who can see afterwards that it happened.
When is Zapier the better choice?
When the steps never change and every app is one of Zapier's 9,000+ integrations. A form entry that becomes a CRM contact and a team message is fixed app-to-app wiring, which is what Zapier is built for.
- Your processes already run on Zaps and they work. Replacing a working Zap with an agent buys you nothing.
- You want agents inside your organisation's Zapier account, sharing its connections and enterprise audit logs, which Zapier's Agents Enterprise plan offers.
You can also run both. A Zap keeps doing the plumbing while Kaer takes the jobs that need a browser or a person's approval, and Kaer can trigger the Zaps you have already built from its own browser. Prices for both are on Kaer vs Zapier Agents.
What does an AI agent for a small business take on?
The jobs that sit between tools. Kaer is built for small businesses, and the jobs owners hand over look like this: chasing last month's unpaid invoices, sending a quote, downloading statements from a portal, writing the Monday report and holding it for a check. Each touches a site behind a login or a decision, which is where fixed wiring hands the job back to a person.
Pricing follows the work. Everything is paid from one prepaid balance, each kind of work has a published rate, and there is no per-seat pricing, so the bill follows the work rather than the headcount. The Starter plan is free and needs no card; the browser and workflows come with paid plans, listed on the pricing page. What a Kaer credit buys explains what uses credits and what happens at zero.
Can developers hand Kaer jobs from their own code?
Yes. Kaer has a public API, so a job can start from your own code. The work goes to the same Kaer Agents you brief in the app, and coding assistants in your IDE can reach them through Kaer's MCP server. Handing jobs to an agent through the Kaer API shows how.
Frequently asked questions
What is the difference between an AI agent and workflow automation?
Workflow automation runs fixed steps set up in advance, such as a Zap's trigger and actions, between apps that have an integration. An AI agent takes the outcome you describe and works out the steps itself.
Is Kaer a Zapier alternative?
For work an agent does, yes. For fixed app-to-app wiring across its catalogue, Zapier is the established choice. Kaer adds reach: it works any tool you log into in its own browser, and builds the missing tool when nothing fits.
Can Kaer automate a tool that has no integration?
Yes, if the tool works in an ordinary browser. Kaer signs in and works it in its own sandboxed browser. You type passwords and one-time codes yourself, and security checks are handed to you.
Does Kaer ask before it acts?
Before consequential steps, yes. Sending, paying, publishing, cancelling and merging wait for a person by default, in its browser as well as through connectors. You can add actions to that list; the agent cannot remove any.
How is Kaer priced compared with Zapier?
Zapier's automation plans count tasks: each successful action is one task, and triggers use none. Kaer is priced by the work, from one prepaid balance at a published rate per kind of work, with no per-seat pricing.
Can I use Kaer and Zapier together?
Yes. A Zap can keep doing the fixed app-to-app wiring while Kaer takes the jobs that need a browser or a person's approval. Kaer can also trigger the Zaps you have already built, from its own browser.
