YouTube Manager — AntiKrust Software

YouTube Manager keeps YouTube organised. It does three jobs, and each works without the others.

CHANNELS
Block a channel and it disappears from the home page, search results, the sidebar and Shorts. Hover any video and press SHUT UP, or add a channel by name in the settings. It starts with a list of 499 blocked channels, which you can edit or clear. Names are matched ignoring case, spacing, full-width letters and the invisible padding people use to get round block lists.

SUBSCRIPTIONS
On your subscriptions page you get tabs beside "Latest": Watch, News, Politics, Podcasts, Science, Tech, Comedy, Music and Favourites. Rename them, remove them or add your own in the settings. Hover a video, press TAG and pick a tab: the channel goes there, and everything it posts from then on arrives under it instead of cluttering Unsorted. Unsorted shows what you have not filed yet; All shows everything. Watch holds single videos and uses YouTube's own Save to Watch later, so your saves stay in YouTube.
There is also a Shorts switch on the page, and a HIDE button that uses YouTube's own Hide, with a DONE button added to the notice it leaves.

LIVE CHAT
- Hide messages by word, phrase or regular expression
- A "say this and you're gone" list: say one of those once and you are blocked outright
- A SHUT UP button on every message
- Automatic blocking of repeat offenders, with Undo
- A threaded view that follows @mentions, so a reply sits under the message it answers

PRIVACY
Everything is stored in your browser. The add-on makes no network requests of its own, collects no data, and only runs on YouTube. Your rules and block list can be exported and imported as JSON.
