FAQ
Frequently asked questions
How is this different from just searching Reddit?+
A keyword search only tells you a subreddit's topic, not whether it's active, tolerates promotion, or actually matches your audience. This tool checks all three before ranking results.
Does it check if a subreddit allows self-promotion?+
Yes — it reads the subreddit's actual rules text for self-promo ratios and link bans and scores each candidate accordingly.
Can I paste a URL instead of describing my product?+
Yes, pasting your product's URL is the fastest path — we extract the topic and audience from the page automatically.
