ChatNote

ChatNote is an AI browser extension that lets you comment on individual paragraphs in AI chat responses before sending your next message, built for people who work with long AI answers in ChatGPT, Claude, and Gemini. Instead of copying a reply into a scratch document and pasting fragments back, you hover over a paragraph or bullet point inside the chat, highlight it, and attach an inline comment. When you have marked up several sections, ChatNote processes all of your comments at once and sends them as your next message, so you can react to multiple parts of a response in a single follow-up. The extension works across major AI chat platforms, with the maker listing ChatGPT, Claude, Gemini, Grok, Kimi, DeepSeek, and LibreChat. It runs in Chrome and Firefox, and the developer states that all data stays local to your browser. ChatNote is aimed at researchers, writers, developers, and anyone who iterates on detailed AI output and needs to address specific claims, code blocks, or list items rather than the whole reply. The primary use is faster, more precise follow-ups: point at exactly what you want changed or expanded and let the extension bundle your notes into one prompt. ChatNote is distributed free through the Chrome Web Store and lists MK2000 as the developer.

Best for researchers, writers, and developers who want to give paragraph-level feedback on long AI chat responses and iterate in a single precise follow-up.
