How to Block AI News Posts on Reddit (2026 Guide)

To block AI news posts on Reddit in 2026, install Ultimate Reddit Filter and paste in a keyword preset covering model names (ChatGPT, Claude, Gemini), company names (OpenAI, Anthropic, Google DeepMind), and general AI hype terms (AGI, LLM, AI-generated). Two minutes to configure. Reddit has no built-in way to filter by topic — an extension is required.

TL;DR

• Reddit has no native keyword filter. You need a browser extension.
• Best tool: Ultimate Reddit Filter (free, Chrome + Firefox).
• Copy-paste the preset below — covers models, companies, and general hype terms.
• For nuclear removal of all AI content: pair with a subreddit blocklist.
• Doesn’t work in the official Reddit app — use Kiwi Browser on Android or Orion on iOS.

Why Reddit has no built-in AI filter

As of May 2026, Reddit’s native tools cover subreddit muting and NSFW toggling only. There is no built-in keyword filter, no topic category blocker, and no way to filter by flair natively. Every post title on your feed is scanned and matched by the extension after the page loads.

The setup

1. Install Ultimate Reddit Filter

Ultimate Reddit Filter — free, open source, actively maintained as of May 2026.

Available for Chrome, Chromium-based browsers (Brave, Edge, Arc), and Firefox.

2. Open the extension and paste the preset

Click the Ultimate Reddit Filter icon → Keywords tab → paste the list below, one term per line:

chatgpt
openai
claude ai
anthropic
gemini
google deepmind
gpt-4
gpt-5
llm
large language model
artificial intelligence
ai-generated
ai art
stable diffusion
midjourney
dall-e
sora
agi
artificial general intelligence
machine learning hype
nvidia ai
ai bubble
ai stocks
sam altman
elon ai
grok
xai
perplexity ai
ai regulation
eu ai act
ai safety
alignment
superintelligence

Click Save. Your feed updates immediately.

3. Add AI-heavy subreddits to the block list

Switch to the Subreddits tab and add:

ChatGPT
OpenAI
artificial
MachineLearning
singularity
LocalLLaMA
StableDiffusion
midjourney
AIArt
Bing

This prevents posts from those subs appearing in r/all and r/popular even if their titles don’t match your keyword list.

4. Enable comment filtering and test

Under Settings, toggle Filter comments on. This hides matching comments in threads you do visit — useful if you’re reading tech subreddits where AI discussion bleeds into unrelated threads.

Tuning the preset

The list above catches most AI coverage. If you’re seeing false positives (legitimate posts about non-AI topics getting caught):

• Remove nvidia ai if you want GPU news but not AI news
• Remove machine learning if it’s catching academic posts you want
• Add nvidia (standalone) if you want all Nvidia posts gone, not just AI-related ones

If you want broader coverage, add: tech layoffs, silicon valley, startup funding, venture capital.

What this won’t do

This filter removes posts from your visible feed. It does not prevent AI-related posts from existing on Reddit, does not affect your Reddit notifications if you follow relevant subreddits, and does not work inside the official Reddit iOS or Android app. For mobile filtering, see the Reddit mobile filtering guide.

Going further

• Nuclear option: If you work in tech and AI posts are unavoidable even with keyword filtering, News Feed Eradicator removes the Reddit home feed entirely. Pair it with keyword filtering for direct browsing.
• Export your list: The AI landscape shifts fast — new models, new companies, new hype terms. Export your keyword list periodically via the extension settings so you don’t lose your tuned version.
• Relabel mode: Use relabel instead of hide to see that posts were filtered without seeing the content. Useful while calibrating the list.

If it’s not working

• AI posts still appearing? Most leaks are image-based posts (screenshots, memes) where “ChatGPT” isn’t in the Reddit title. Add the specific subreddits where you see leaks to the Subreddits tab.
• Too many false positives? artificial intelligence is broad — replace it with artificial intelligence news or ai hype if it’s catching legitimate ML research you want to see.
• Mobile not working? The Reddit mobile app cannot run extensions. Install Kiwi Browser (Android) or Orion (iOS) and add the extension inside either.
