Browser Copilot sits in your Chromium browser and allows you to select elements or describe interactions in natural language. It then uses GPT-3.5 to generate reliable CSS/XPath selectors and complete test code snippets for popular frameworks like Selenium, Playwright, and Puppeteer. You can export tests, capture user flows, and refine generated scripts all within the extension pane. By automating selector creation and boilerplate code, it accelerates test development, reduces flakiness, and keeps your test suite maintainable.
