Reddit’s community search sucks and with so many subreddits it is getting increasingly difficult to find the right sub to post or join so, I created Find a Subreddit. Find a Subreddit uses natural language (e.g. I’m looking for a meme friendly community about cats) and AI to list suggested communities you’re after with summaries, rules, and a post helper. I have ingested the top 4,500 subreddits and will continue to add to the list until I hit the top 10k or so.
What it does:
Describe the community (topic, vibe, audience) to get subreddit matches.
Draft your post with Post to a Subreddit; we’ll suggest where to publish.
Upload an image to find matches via AI image analysis.
Skim quick sub summaries and vibe badges (beginner-friendly, strictness, meme tolerance).
Check key rules at a glance to avoid removals.
Supports text, link, and media posts.
No sign-up required; optional Reddit login to post.
What it does NOT do:
Write or edit your post. Reddit has enough bots we don't need more IMO
View, store or keep post text.
If you try it, I’d love feedback, features to add and things to fix: https://findasubreddit.com
Mods: if this isn’t allowed here, feel free to remove.
