Agent Moderator

Evaluate YouTube Live chat via the official API and manage per-broadcaster author lists locally. Does not modify YouTube UI.

Agent Moderator is a Chrome extension that filters YouTube live chat on your own screen. It retrieves live chat messages through the official YouTube Data API and uses TypeSafe AI's Jev, when explicitly enabled, together with repeated-post detection to identify authors whose comments should be hidden. Filtering affects only your own view. The extension does not delete comments, ban authors, or change what other viewers see. Features: - View collected comments and AI evaluation scores. - Adjust the filtering threshold. - Review hidden authors for each live stream and restore their comments. - Delete locally stored hidden-author data. - Use the extension interface in English or Japanese. Requirements: You must provide your own YouTube Data API key. AI evaluation also requires your own TypeSafe AI Jev API key. You are responsible for applicable API quotas and Jev usage charges. Data handling: When you enable Jev evaluation, the extension sends the target comment's text and posting time, plus collected comments from the same author within the preceding 60 seconds, to TypeSafe AI. This includes up to 20 comments in total, including the target. Comment text may contain personal information. API keys, filtering settings, agreement status, and per-stream hidden-author data are stored locally in your Chrome profile and are not synced to other devices. Limitations: AI evaluation may produce incorrect results or miss problematic comments. Ended live streams and chat replays are not supported. Agent Moderator is not an official YouTube or Google product. What's new in 1.0.2 - Hidden-author settings now carry over to other live streams from the same channel. - While chat collection is running, switching to another live stream in the original YouTube tab automatically switches the collection target. - The hidden-author list now shows the comment that first triggered hiding an author. - The hidden-author button now shows the number of hidden authors. - Super Chats now appear as colored cards combining the author's name, amount, and comment text.
