A browser agent operates the browser. You state the outcome
The test is who does the clicking. Say "file this month’s expense report" and the browser works through the inbox and four vendor portals while you do something else.
A browser agent is an AI that operates a web browser the way a person does: opening tabs, navigating, clicking, typing into fields and reading what renders, to finish a task you delegated. The test is who does the clicking. State an outcome ("register us in these three portals", "pull these 200 listings into a sheet") and have the browser work while you do something else, and that is an agent.
In Strawberry, an agentic browser for Mac and Windows, companions work in your real logged-in session and pause on an approval card before anything consequential. Twenty-three expense lines collected from an inbox and four vendor portals, entered into the expense tool, and waiting for one click is the ordinary shape of it.
How is it different from a chatbot or copilot?
Three separations. Actor: a chatbot advises while you operate, and an agent operates while you review. Scope: a sidebar sees the page you are on, and an agent traverses many tabs and sites in one task, including the logged-in ones where your work lives.
Deliverable: a chatbot returns text in a panel, and an agent returns changed state: the filled sheet, the updated record, the staged email. The wider taxonomy is untangled at agentic browser vs AI browser.
What does one do on a real task?
The instruction: "collect this month’s receipts from the inbox and the four vendor portals, and file the expense report." The companion searches the inbox for receipts, visits each vendor portal in your already-signed-in session to download the invoices, and extracts date, amount, VAT and category from each.
It enters the lines into the expense tool in another tab and stops. The submission is consequential, so it waits on an approval card while you glance over the 23 lines. One instruction, one review, one click. A broader inventory of job shapes is in use cases.
What separates a real agent from a demo
Properties that never show in a launch video.
It works in your accounts without taking your passwords. It pauses before irreversible actions and shows the actual payload. It flags what it could not do instead of narrating success. It runs the same task on a schedule without degrading.
And you can watch finished runs of real tasks rather than curated clips. Ours are published at real runs, approval pauses included, and the login model is on the security page.
How to run the test yourself
Take one task you would hand a capable temp, write it as sources, steps and what done looks like, and watch who does the clicking.
If the browser works while you do something else and the finished thing is waiting for your approval, you are looking at an agent. Strawberry is free for Mac and Windows.
