Tabrein

Give your AI app a real browser: it clicks, types, fills in forms and uploads files in your Chrome, under your permissions.

Tabrein gives your AI a real browser. Connect the AI app you already use to Chrome through the Model Context Protocol (MCP). Your agents click, type, fill in forms, upload files and move between tabs in the browser you are signed in to — no headless bot, no copied passwords. WHAT IT DOES • Whole forms in one call: text fields, selects, checkboxes and radios, then checked • File uploads from your computer, including hidden upload fields • Real clicks, typing, hover, drag and keys that sites treat as normal input • Find text or controls on long pages without sending the whole page to the model • Open, switch and close tabs; go back and forward; answer alerts and confirms • Accessibility snapshots and screenshots when the AI needs to see the page SEVERAL AGENTS AT ONCE Each AI session gets its own tab in a labelled tab group, and a soft frame around the page shows which tab is being driven. Agents keep working in background tabs while you use the browser, and they cannot take each other's tabs. The popup shows every session and what it is doing. YOU STAY IN CONTROL • Allow, Ask or Block each sensitive capability: file uploads, password fields, JavaScript, screenshots, tabs and console logs • Typing into password fields is blocked by default; uploads and scripts ask first • "Ask" opens a Tabrein window outside the page, so the agent cannot click it • Keep agents away from whole sites, such as your bank • One switch connects or disconnects the whole browser PRIVATE BY DESIGN Tabrein talks only to the Tabrein server on your own computer (127.0.0.1). Page content goes from your browser to the AI app you connected and never through our servers. Tabrein contains no analytics or advertising code. The only request to our servers is a licence check. SETUP 1. Install Tabrein and pin it to the toolbar. 2. Add the Tabrein server to your AI app. Step-by-step instructions: https://tabrein.com/#setup 3. Paste your licence key in the popup and give your AI a task. Tabrein is a subscription with a 7-day free trial. It does not include an AI model; you use the AI app you already have.
