Google-Docs-style follow-up comment threads on Gemini, ChatGPT and Claude — highlight text, ask in the margin, keep your place. Full Feature Set: https://marginalia.midhun-krishna-usa.workers.dev/ Ask follow-up questions in the margins - without burying the answer you're reading. When an AI gives you a long answer and one phrase needs unpacking, you normally ask in the main chat and scroll away from your place. Marginalia gives you Google-doc-style comment threads instead: highlight the phrase, ask your question in a comment box that opens right next to it, and the reply streams into the box while the original answer stays put. How it works: * Highlight text in an AI answer on chatgpt.com or claude.ai or gemini.google.com * Click the Comment pill ( or right-click -> "Ask About..." or press Ctrl + Shift + H) * A comment thread opens in the right margin, anchored to your highlight * Ask follow-ups in the thread - replies come from the AI you're already using. Features: * Multi-turn threads that persist per conversation and re-anchor when you return * Docs-style layout: focusing a thread aligns it with its highlight * Minimize threads to chips, expand to full screen, or resolve them for later * An all-threads panel (Alt + Shit + A) with open/resolved filter and click-to-jump * Follows each site's light/dark theme * Keyboard-first: cycle threads with Alt+↑/↓, re-bindable shortcut Your data stays yours: Threads and settings are stored locally on your browser. Your questions go only to the AI service you are already using - either through your existing signed-in session or through the providers official API if you add your own API key in Settings ( ChatGPT requires an OpenAI key). Keys are stored locally and sent only to that provider. Marginalia has no server and collects nothing. The source code is open-source and is available for community review.
