About

Keep abusive usernames and comments out of your app without blocking people from Scunthorpe. Unprofane catches profanity hidden behind swapped letters, symbols and spacing in 17 languages, scores text for toxicity, and returns a censored version ready to display. Try to fool it in the live playground, then build with free test keys before you pay. Paid plans start at $9 a month. Using Google’s Perspective API? It shuts down after December 31, 2026. Unprofane is a drop-in replacement, so you switch without rebuilding your integration. Questions, or a result that looks wrong? hello@unprofane.com
