Unprofane

A profanity and toxicity API for the text people type: comments, usernames, chat and reviews. It decides allow, review or block and tells you why: the word it matched, where it was, and the disguise it wore.

• Hard to fool. Leetspeak, look-alike letters from other alphabets, invisible characters, spaced, stretched and reversed words are undone before the words are read, and each disguise is named in the answer.
• Lets the innocent through. Scunthorpe, the surname Dickinson and the cockatoo pass; false positives are counted on the open Scunthorpe Test .
• A drop-in for the Perspective API, which Google shuts down after December 31, 2026: the same request, the same JSON, at a new host. Migration guides .
• One text, four audiences: kids, teen, standard or strict.

On Apify: Perspective API Alternative: Profanity & Toxicity Check , which checks texts in bulk from a list or another Actor's dataset.
