Profanity Detector & Filter

Detect and mask profanity in text — get a clean (masked) version, the exact flagged words with positions and severity, and a simple isClean boolean built for moderation pipelines.

Live on the Apify Store — run it instantly or call it as an agent tool via Apify MCP.

What you get

Smart matching — a built-in multi-tier word list catches leetspeak (f4ck, sh!t), spacing and punctuation obfuscation (f.u.c.k, s h i t), and stretched letters (fuuuck).
No false positives — word-boundary anchoring defeats the Scunthorpe problem, so Scunthorpe, class, assassin, and Cockburn stay clean.
Masked output — a ready-to-publish cleanedText with profanity replaced by your chosen mask character.
Severity tiers — every match is labeled mild / strong / severe, plus an overall severity for the whole text.
Positions — exact start/end offsets for each match so you can highlight or redact in your own UI.
Bulk mode — pass a single text or an array of texts; each gets its own result row.
