Free tool
Describe your product and get a verified shortlist of communities where your buyers post, with member counts, activity, and how each one treats self-promotion. Guessing this list by browsing Reddit takes an afternoon; this takes twenty seconds.
Results come back best-fit first, and the fit ranking deliberately ignores size. A 40,000-member subreddit where your exact buyer asks “what tool should I use for…” every week is worth more to you than r/Entrepreneur’s four million members, most of whom will scroll past. Big generic communities are for learning the language of your market; small specific ones are where recommendations convert.
The promo label is the one to take seriously. Communities marked strict will remove standalone product posts, and repeat offenses feed Reddit’s sitewide spam filter. If you have already been posting and your engagement dropped to zero, run our shadowban checker before you post anything else.
After the list
Knowing your ten subreddits is the first hour of Reddit marketing. The other hours go to reading threads, deciding which ones deserve a reply, and writing something that survives the moderators. These guides cover that part.
How to spot the threads where a product mention genuinely helps, and skip the rest.
The rules, the mistakes, and the reply pattern that keeps accounts alive.
How CueScout keeps finding new communities as your keywords surface conversations.
You describe your product (or paste your site URL and we read the title and description). An AI model maps that to candidate communities, then we verify every single name against Reddit before showing it: live member counts, activity, and whether the subreddit still exists. Anything the model made up or that has gone private gets dropped.
Start from the problem you solve, not your product category. A bookkeeping tool for freelancers belongs in r/freelance and r/smallbusiness, where the pain lives, at least as much as in r/accounting. This tool suggests both kinds: the big obvious communities and the smaller ones where your exact buyer asks questions.
The honest answer: the communities that allow promotion (r/SideProject, r/alphaandbetausers, r/EntrepreneurRideAlong) have audiences full of other founders, not buyers. The subreddits with your actual customers usually restrict self-promotion. That is why each result here carries a promo note, and why replying helpfully in strict communities tends to beat launch posts in tolerant ones.
Mostly no, and doing it anyway is how accounts get shadowbanned. Subreddits marked "strict" here remove standalone promo posts. The pattern that works: answer questions where your product is genuinely the answer, disclose that it is yours, and keep the ratio of helpful comments to product mentions high.
We only show communities we could verify on Reddit at the moment you searched, and we cap the list at ten so it stays a shortlist rather than a dump. Private, banned, and 18+ subreddits are excluded. If a community you know is good is missing, that is a limitation of a one-shot suggestion — a full CueScout scan looks at where relevant conversations actually happen instead of guessing from a description.
Three lookups per day per network. Each search runs a paid AI model plus a batch of Reddit checks, and this tool is free, so the ceiling keeps it available for everyone. Identical searches are cached, so re-running the same description does not burn a lookup on our side.
