AI Buddy is a free, open-source Chrome extension that changes how you interact with AI while browsing. Select any text on a webpage and send it to ChatGPT, Claude, Gemini, or DeepSeek — no copy-pasting. Capture annotated screenshots with crop, highlight, and arrows before sending. Features 10 starter scenarios, keyboard shortcuts, and per-platform send behavior. Privacy-first: no backend server, your data goes directly to the AI platform you choose.
