How to Filter Your Reddit Feed by Topic
Last updated: August 2026
Quick answer: Reddit’s own mute options stop at whole subreddits. The free Dehook extension filters your Reddit feed by topic: a local AI reads post titles and hides posts about subjects you block, even inside subreddits you keep. One blocklist covers both Reddit and YouTube.
Reddit gives you two blunt tools: mute a subreddit or leave it. Neither helps when the problem is a topic that spreads across every community, which is exactly how politics, gossip, and hype behave.
Semantic filtering for Reddit
Dehook applies the same local AI it uses on YouTube to Reddit post titles. Add a topic once and both feeds respect it. For Reddit specifically that means you finally get the middle ground between leaving a subreddit and enduring everything in it.
Filter Reddit in 3 steps
- Install Dehook. Add the free extension to your browser.
- Add topics. The same Topics box covers Reddit: add politics, gossip, spoilers, anything.
- Browse a filtered feed. Posts about blocked topics are filtered from your home feed and Popular, across all subreddits.

One topic list filters both Reddit and YouTube.
FAQ
How is this different from muting subreddits?
Muting removes whole communities. Topic filtering is finer: you keep r/worldnews but lose the outrage threads, keep r/gaming but lose one specific game. The AI reads each post title individually.
Better than RES keyword filters?
RES matches literal keywords, so you end up maintaining twenty terms per topic and still miss half. The AI classifies meaning, which is why one entry called politics outperforms a hand-built keyword list.
Does it work on new Reddit and old Reddit?
Dehook targets the current Reddit interface. Old Reddit users typically already run RES; Dehook is the modern-Reddit equivalent with semantic filtering.
Can it hide Reddit ads too?
Yes, there is a separate Hide promoted posts toggle for sponsored content in your feed.
