Keep abusive usernames and comments out of your app without rejecting harmless names. Unprofane catches profanity hidden behind swapped letters and symbols, checks text for toxicity, and gives you a censored version ready to display. Try to fool it in the live playground. Free test keys let you check it in your own app before paying; plans start at $9/month. Already using Google's Perspective API? Switch without rebuilding your integration.

Hi, I'm Tomer, co-founder of Unprofane. A word list can block a harmless name and still miss an insult with a number in place of a letter. We built Unprofane to give apps and communities a better answer before text reaches other users. The playground is open: try a disguised insult, then try Scunthorpe or another harmless name. Every result shows what it caught and why. You can also get free test keys to see how it handles your app's own examples. Our launch offer takes 50% off your plan's monthly price for the first three months if you start by January 31, 2027. Code: LAUNCH50. Questions or a result that looks wrong? Reach us at hello@unprofane.com. I'd like to hear what your current filter keeps getting wrong.
