Overview

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.
