Find the Right Subreddit for Your Post.

Paste an existing draft to compare subreddit suggestions. Risk labels are model estimates, not calibrated probabilities or permission to post; check each community's current rules yourself.

Review Community Fit

Suggestions can help narrow your research, but they may not reflect current rules or moderation decisions. Open each community, check its rules and recent posts, and make the final decision yourself.

FIND THE RIGHT FIT

Compare communities for a draft you already have

Paste a draft to get candidate communities to research. This page is for matching an existing post, while the product-based subreddit finder helps you explore communities from a product or topic.

A match or risk label is only a starting point. It does not confirm current rules, account eligibility, moderator approval, or whether a post will remain visible.

Search with intent

Find subreddits based on what your draft is trying to do, not just a keyword match.

Compare better options

See when a smaller or similar subreddit may be a better first post than the obvious big one.

Post with more confidence

Use model-generated signals to prioritize manual checks, not to approve a post.

How to find subreddits without the usual trial and error

Compare topic fit and suggested risk, then open the source community to review current rules, flair, account requirements, and recent posts.

Why the biggest subreddit is not always the best one

A smaller community is not automatically a better fit. Compare its topic, rules, audience, and recent discussion before choosing it.

POSTING STRATEGY

A Relevant Match Still Needs a Rule Check.

A draft can be relevant to a community and still be disallowed by its rules or unsuitable for the current thread. Use suggestions to guide research, then decide manually.

100,000+ Active Subreddits

Each community has its own rules, culture, and moderation strictness. The right match changes the outcome.

Suggestions are not approval

A model estimate cannot predict moderator decisions or confirm current community rules.

Post content matters most

This tool analyzes your real post text to find communities where your specific content is more likely to fit.

Manual Review Checklist

1

Open the source community

Check the current rules, allowed formats, flair, account requirements, and recent posts.

2

Read the rules before every post

Even when the risk looks low, always read the rules for formatting, flair, and posting schedules.

3

Stop when promotion is prohibited

A favorable score, disclosure, or link-free wording does not override a rule that prohibits promotion.

Use candidate matches as a research starting point, not posting approval.
