Browser Use
ELI5 — The Vibe Check
Browser use is AI controlling a real browser — scraping, filling forms, navigating UIs — computer use but scoped to the web. No API? No problem. The AI just opens Chrome and clicks the same buttons a human would. It can log in, extract data, submit forms, and navigate multi-step workflows entirely through the browser interface. Roughly 40% of the internet becomes automatable overnight.
Real Talk
Browser use refers to AI agents controlling headless or visible browsers (via Playwright, Puppeteer, or purpose-built frameworks like Browser Use and Stagehand) to interact with web UIs as a human would. It's especially useful for sites with no API, legacy enterprise portals, and tasks involving dynamic JavaScript-rendered content. The failure mode is fragility — any UI change breaks the automation, since it's click-targeting, not API-calling.
