Testbook.ai

Testbook.ai is a no-code testing tool, delivered as a Chrome extension, for automating regression and UI testing of web applications. Testers record interactions with an app by simply using it, and Testbook plays the recorded steps back later as a repeatable test, without writing test scripts. Its AI layer focuses on visual testing, detecting differences between an expected and actual UI screenshot, including subtle changes that manual review might miss, and generating detailed reports with test history over time. The platform connects to third-party device and browser cloud providers, including Sauce Labs, BrowserStack, Testing Bot, and LambdaTest, for running tests across different browser and device combinations. Additional capabilities described in third-party listings include self-healing test scripts that adapt when page elements change, handling of iframes and Shadow DOM, multi-window and multi-tab support, and drag-and-drop test steps. Testbook.ai targets QA teams and developers who want to reduce manual regression testing effort without hand-coding automation scripts. The main product site was unreachable during this review, so this summary draws heavily on the Chrome Web Store listing and third-party reviews rather than the company's own pricing or background pages.
