Write Tests in Plain English
Describe what to test the way you'd explain it to a teammate. AI does the rest. No code, no selectors, no framework.
Test-Lab.ai lets you create a full end-to-end browser test by writing what you want to verify in ordinary English. "Sign up with a new email, confirm you land on the dashboard, then log out" is a complete test. There are no CSS selectors to hunt for, no test framework API to memorize, and nothing to install. An AI agent reads your description, drives a real browser, and reports what happened with screenshots and a trace.
The problem it solves
Traditional automation makes the person who understands the product (the founder, PM, or QA lead) hand the work to whoever can write Selenium or Playwright. Intent gets lost in translation, the backlog grows, and tests rot because only one person can touch them. Plain-English tests put authoring back in the hands of the people who know what "correct" looks like.
How it works
Describe the flow
Type the steps and assertions in plain English, like a short checklist. Reference your real data and credentials with simple tokens when you need them.
AI plans and drives a real browser
An AI agent interprets each step, navigates your live site in a real Chromium browser, and decides how to interact with the page semantically instead of relying on brittle selectors.
Get an evidence-backed result
Every run returns pass/fail per step with screenshots, a Playwright trace, and network logs, so you can see exactly what the agent saw.
Refine by editing the words
Need a change? Edit the English. There's no script to keep in sync, so non-developers can maintain the suite alongside engineers.
Why it matters
Anyone can author
Founders, PMs, designers, and QA can all write and read tests. Testing stops being a developer-only bottleneck.
Nothing to install or configure
It runs in the cloud. No Node version, no browser drivers, no CI runner to babysit before you can see a result.
Tests read like documentation
A plain-English suite doubles as living documentation of how your product is supposed to behave.
Frequently Asked Questions
Common questions about plain-english test creation in Test-Lab.ai.
Correct. You describe tests in English and the AI agent handles execution. If you later want the underlying Playwright code, Test-Lab.ai can generate and hand it to you, but writing or maintaining code is never required to create or run tests.
