Chat Signal

AI-powered live chat intelligence for YouTube and Twitch. Clusters messages, tracks sentiment and trending topics. 100% local.

See what live chat is really saying — without losing it in the scroll. Chat Signal analyzes YouTube and Twitch live chat in real-time and shows you: - **Questions people are asking** — surfaced instantly so nothing gets buried - **Chat mood** — is the room excited, positive, confused, or frustrated? - **Trending topics** — the words and emotes that keep coming up - **Session history** — review what chat talked about after the stream ends **For creators and moderators:** Spot audience questions in real time, catch sentiment shifts early, and get an AI-generated summary of what happened during the stream. Free. No account needed. All processing happens locally in your browser — no chat data ever leaves your computer. A small encoder model (~23MB) is downloaded once on first use for smarter clustering; the optional AI summary model (~400MB) downloads only if you opt in. Works with YouTube and Twitch live streams.
