How to Block Keywords on YouTube (Mute Words Like on Twitter)
Last updated: August 2026
Quick answer: YouTube has no native mute-words feature. Install the free Dehook extension and add words under Custom keywords: any video whose title or channel contains a muted word is filtered from your feed. For everything a literal keyword misses, add the subject as an AI topic instead.
Twitter and Reddit users have muted words for years. YouTube never shipped the feature, which is strange for a site whose entire interface is a wall of titles engineered to grab you.
Two filters, one goal
Dehook gives you both layers. Keywords are the scalpel: literal, immediate, no AI required. Topics are the net: the local AI classifies meaning and catches what literal matching cannot. Most people use a handful of each: keywords for specific irritants, topics for whole categories.
Mute a keyword in 3 steps
- Install Dehook. Add the free extension to your browser.
- Add keywords. Open the popup, type a word or phrase under Custom keywords, click Add. Repeat freely.
- Browse without it. Videos matching the keyword are filtered instantly. Keywords use word-boundary matching, so art does not accidentally block start.

FAQ
When should I use a keyword and when a topic?
Keywords are instant, precise, and need no AI: perfect for specific names, shows, or phrases you never want to see. Topics use the AI to catch a subject however it is phrased. Rule of thumb: exact word, use a keyword; general subject, use a topic.
Do keywords work while the AI model is still downloading?
Yes. Keyword, channel, language, and Shorts filtering all work instantly without the model. Only topic filtering needs the one-time model download.
Can I mute spoiler phrases?
Yes, phrases work: add ending explained or episode 5 while you catch up on a series, then remove them after.
Is there a limit?
No practical limit on the number of keywords.
