This browser is connected to your Claude Code session. The sidebar is your co-pilot: it can control this window, read pages, edit CSS, and pass everything back to your terminal.
The sidebar chat is a Claude instance that controls this browser. Say "go to my app and check if login works" and watch it navigate, click, fill forms, and report back. It sees the same page you do.
Click the Cleanup button in the sidebar. An AI reads the page, identifies overlays, paywalls, cookie banners, and clutter, then removes them. Articles become readable. Works on news sites, docs, anything.
The screenshot button captures a cleaned, annotated screenshot and sends it to your Claude Code session as context. "What's wrong with this page?" now has a visual answer.
The sidebar can edit CSS and DOM on any page. "Make the header sticky" or "change the font to Inter." Changes happen live. The sidebar reports what it changed back to your Claude Code terminal.
