How to filter keywords on Reddit (and what Reddit offers instead)
Reddit doesn’t have a keyword filter for your feed: you can’t tell it to hide every post that mentions a word. What it offers instead is muting whole communities, hiding posts one at a time, and settings for mature content. Here’s how to use each, and how to filter Reddit posts and comments by topic on a computer.
Updated November 2, 2026What Reddit lets you do
Mute a community
Muting keeps a community out of your Home feed (including recommendations), the Popular feed and your notifications. You can mute up to 1,000.
- On a community’s page, open the three dots (⋯) menu and choose to mute it.
- On a recommended post in your Home feed, the three dots menu offers Show fewer posts like this.
- Your full list is in Settings, under Muted communities, where you can unmute any of them.
Our guide to blocking a subreddit goes through it on each device.
Hide a post
Open the three dots on a post and choose Hide. It disappears from your feeds, and you can find it again in the Hidden section of your profile. It’s one post at a time. See how to hide posts on Reddit.
Turn off Home feed recommendations
Reddit fills your Home feed with posts from communities you haven’t joined. In your account preferences, you can switch those recommendations off, so Home sticks to communities you’ve joined.
Mature content settings
In Settings, under Preferences:
- Turn off Show mature (18+) content to keep NSFW posts out of your feeds and search.
- Or turn on Blur mature (18+) images and media, which keeps those posts but blurs them until you tap.
Both depend on a post being marked NSFW by its author or the community’s moderators.
What about keyword filters?
Reddit has none for readers. Moderators have word filters for their own communities, but that decides what gets posted there, not what you see.
Browser add-ons made by other people can filter posts by keyword, mostly on old Reddit (old.reddit.com). They aren’t made or checked by Reddit, so look at what access they ask for before installing one, and know that they match exact words in titles.
What’s still missing
- Topics cut across communities. Politics turns up in r/pics, spoilers in movie subs, a breakup story in r/AskReddit. Muting communities can’t follow a topic.
- Comments. None of Reddit’s settings filter comments by what they’re about. You can open a harmless post and find the thread underneath is exactly what you were avoiding.
- Titles that don’t use your word. Even a keyword add-on misses a post about the same thing in different words.
- Hiding is one post at a time. Tomorrow’s version of the same post shows up anyway.
Filter Reddit by topic, comments included
Remedy is a Chrome extension that filters Reddit by meaning, not keywords. Describe what you’re done seeing, like “no spoilers for the show I’m watching” or “nothing about the election”, or switch on a built-in category like Political or Sad or depressing, and it removes matching posts and comments as you scroll, in any community, whatever words they use.
It works on new and old Reddit, and the popup lists everything it took out. On Plus, it checks images and video frames too. It works on a computer, in Chrome, not in the Reddit app, and on X, YouTube, Instagram and other sites as well.
Questions
Can you block keywords on Reddit?
Not with Reddit’s own settings. Reddit lets you mute communities and hide posts, but it has no muted words list for your feed.
What does muting a community on Reddit do?
It keeps that community out of your Home feed (recommendations included), the Popular feed and your notifications. You can still visit it directly, and unmute it any time.
How do I stop seeing NSFW posts on Reddit?
In Settings, under Preferences, turn off Show mature (18+) content, or turn on Blur mature (18+) images and media. Both rely on posts being marked NSFW.
