An automatic profanity filter for video and audio

Profanity filter usually means one of two things. One is a live filter, in a browser extension or a chat setting, that catches words as they happen; Redactify is not that, and it does not work on live streams or calls. The other is a filter you run over a finished recording to produce a clean version, and that is what this is: upload a video or audio file, decide what counts as profanity for your audience, and download a copy with those words bleeped, muted or replaced, and optionally the speaker's mouth blurred.

The deciding part is what makes it a filter rather than a blunt instrument. Words are grouped into nine categories in three groups: profanity (common swearing, light profanity, slurs, sexual content, religious terms), demonetisation risks (violence and harm, sensitive topics, drugs and substances) and platform-specific extras. Each is its own switch. A family channel might turn on all nine; a comedy podcast might want only slurs; a gaming channel heading to YouTube wants the YouTube Ad-Friendly set, which is a preset that flips the right switches for you. Pro accounts can add their own words to catch, and a whitelist of words never to catch, which is how a brand name or a regional word that trips a list stays in.

Underneath, the file is transcribed word by word, each word is checked against the categories you chose, with common endings and multi-word phrases handled, and every catch is listed with a timestamp before anything is downloaded. English is the most accurate; Spanish, French, German and Portuguese are in beta.
