About

Branch AI – Ask AI Anywhere

Branch AI is a Chrome extension that makes AI available right where you need it — directly inside your browser. Whether you want to highlight text for instant inline answers or open a popup for side questions, Branch AI keeps AI always by your side without breaking your workflow.

Features

Why Branch AI?
Unlike other AI chat tools that lock you into a single flow or require switching to a separate app, Branch AI lets you create follow-up threads, side chats, and inline questions without breaking your browsing experience. 
We built it to solve a simple frustration: when exploring ideas with AI, one answer often sparks multiple follow-up questions — but traditional chat tools make you open a new tab or lose your context. With Branch AI, you can instantly branch off, get summaries, translations, or side explorations directly in your browser, keeping your workflow smooth and uninterrupted.
