Reddit post rule checker.
Paste your draft before you post it. We'll flag likely self-promo and rule-violation red flags a strict moderator, or the community itself, would react to.
Why use the post rule checker
Most removed Reddit posts break a rule the author never read, or read as an ad to a community that hates ads. A removal costs you the post, and repeated removals can get an account banned from that subreddit. Checking the draft first is cheaper than finding out from a moderator.
How it works
- 1
Paste your draft
Add the title and body, up to 4,000 characters. Add the subreddit name if you know where it is going.
- 2
Get red flags
The checker reads it the way a strict moderator would and lists what is likely to get it removed or downvoted.
- 3
Fix and post
Rewrite the flagged parts, then read the subreddit's own rules once more before you hit post.
What it looks at
Self-promotion
Links, product names and calls to action that make the post read like an advert.
Common rule breaks
Things many subreddits ban, such as asking for upvotes, low-effort posts and missing disclosure.
Tone
Wording that reads as marketing copy rather than a person talking to peers.
Tips for better results
- Lead with the useful part. If the post only works with your link in it, it is an ad.
- Say that you work on the product when you mention it. Redditors find out anyway.
- The checker does not read the subreddit's live rules page, so check the sidebar yourself.
Frequently asked questions
Does the post rule checker read each subreddit's actual rules?
No. It uses AI to judge your draft against common Reddit rules and the norms of the subreddit you name. Always read the sidebar before posting.
How long can my post be?
Up to 4,000 characters, which covers almost every Reddit post.
Will this stop my post from being removed?
It lowers the risk, but moderators have the final say and every subreddit runs differently.
Is it free?
Yes, with no signup.
