Everything the subreddit expects, before you press Post
Subreddits enforce rules you can read and gates you cannot see. PostGuard puts both next to the box you're typing in: the rule summary, whether you clear the karma and account-age thresholds, and what in this specific draft is likely to trip a filter.
PostGuard estimates. It cannot promise.
Every score is inferred from public information only — a subreddit's written rules and your own public Reddit account. AutoModerator's configuration and Reddit's own spam filters are private to moderators, so no tool, this one included, can see them. Treat the result as a reference point, never as permission to post.
Rules, summarised and matched
The subreddit's own rules are parsed for the things a machine can check — karma minimums, account age, banned links, required flair, title prefixes, self-promotion ratios, and whether AI content is allowed there at all.
Your account against those gates
Your Reddit karma, account age, email verification and recent posting frequency in that subreddit, checked against what the rules ask for. Every line shows its source, so you can disagree with it.
A probability, never a promise
AutoModerator and the rest of a subreddit's automated moderation setup are private. You get a score out of 100 with the reasons listed — and an explicit list of what could not be verified, so "unknown" never gets read as "fine".
