How to Block Kids Content on YouTube
Last updated: August 2026
Quick answer: Install the free Dehook extension, open the popup, and add kids content as a blocked topic. Dehook’s local AI reads every video title and filters kids content content out of your feed and recommendations, even when the title never uses the word. YouTube itself has no topic filter, so an extension is the only way.
If a child sometimes uses your account, your recommendations fill with nursery rhymes and toy videos for weeks. Filtering kids content reclaims an adult feed without touching the child’s own profile.
Why keywords and “Not interested” are not enough
Clicking Not interested barely works: Mozilla’s RegretsReporter study measured that it prevents only about 11 percent of similar recommendations. Keyword blockers do a bit better but only match exact words, and most kids content videos never put the obvious word in the title. Dehook runs a small AI model locally in your browser that understands what a video is about, so the filter holds.
What happens after you block it
Blocked videos are blurred with a “Filtered by Dehook” cover (or removed entirely in Hide mode). You can always click to reveal one. And because you stop clicking and watching kids content content, YouTube’s own algorithm gradually stops recommending it too: you are starving the recommendation loop at the source.
Block kids content in 4 steps
- Install Dehook. Add the free Dehook extension to Chrome, Edge, Brave, or any Chromium browser.
- Open the Topics section. Click the Dehook icon in your toolbar and find the Topics box.
- Add "kids content". Type kids content and click Add. Dehook's local AI now recognizes kids content videos even when the title never uses that word.
- Reload YouTube. Refresh your tab. Videos about kids content are blurred out of your feed (or fully hidden if you prefer Hide mode).

FAQ
Does this really catch kids content videos that never mention it in the title?
Yes, that is the point of the AI filter. A plain keyword blocker only matches exact words, but Dehook runs a small language model in your browser that reads each title and decides what the video is actually about. It catches kids content content that a keyword list would miss.
Does YouTube have a built-in way to do this?
No. YouTube only lets you block channels or click Not interested, and Mozilla research found Not interested only prevents about 11 percent of similar recommendations. There is no native topic filter, which is why an extension is needed.
Is my data sent anywhere?
No. Dehook’s AI runs entirely inside your browser. Titles are classified locally and nothing about your viewing leaves your computer.
Is this for blocking content FOR kids or ABOUT kids?
This filters kids-oriented content out of an adult’s feed. For making YouTube safer for a child, see our family guides instead.
