Censor Words

Censor Words lets you automatically detect and silence specific spoken words — like swear words, names, addresses, or private information. The censor word list is saved and applied across all your video projects.

Note

Censor Words is currently available on iOS only (for now) and requires iOS 18 or later.

How to use

1. Tap Audio on the toolbar and select Mute words... (or toggle Also mute audio during subtitle generation).
2. Enter the words or phrases you want to censor (e.g., specific names, brands, or profanity).
3. Select the spoken language of the video.
4. Tap Detect & Mute. TrackBlur will transcribe the audio locally, identify matching ranges, and apply muting/beeping.

Where it applies

• Subtitles: Matched words are masked in the visual captions (e.g., fuck is rendered as f***).
• Audio: Spoken words are silenced or replaced with a standard censor beep tone on the timeline.

Review & Exclude Matches

You are always in control of the edits:

• Open the Detected words list to review every matched word and its timeline timestamp.
• Toggle individual matches on or off if a word was incorrectly detected.
• Tap a match row to jump the video player's playhead directly to that moment to preview it.
• Delete any generated range directly from the audio timeline to restore the original sound.

Premium

Masking words in subtitles is completely free. Silencing or replacing matched words with a beep tone in the video's audio track requires a Pro upgrade.
