About this extension

The most powerful and intuitive YouTube chat filter extension.

Read the publisher’s full description

Capture messages from YouTube chat based on filter rules. YtcFilter works alongside the standard YouTube chat and is compatible with third-party addons and websites such as Holodex. Many types of filters are supported, including: - Author roles (Moderator, Member, Channel Owner, Verified, etc.) - TL tags ([EN], [JP], etc.) - Message types (superchats, membership messages, etc.) - Text filters (contains, starts with, ends with, equals, regex, etc.) Filtered chat messages are archived into persistent storage. Message logs can be easily imported/exported as text files, json files, or screenshots.

100% EXACTLY what I needed. Thank you for such a great tool!

Dominick Nigra·28 Oct 2025

Doesn't work, not sure why but no amount of tinkering in the settings does anything and there are no error messages.
