Conversation Redact: chats, captions, and audio

Redact Teams, Slack, and WhatsApp chats, WebVTT and SubRip transcripts, and meeting recordings with beep, silence, or forensic voice anonymization. Video is not supported.

Conversation Redact is included on Trial, Starter, Pro, Firm, and Enterprise. It is on with the plan. Outbound Guard seats do not include it.

How it works

Audio

Beep, silence, or forensic voice anonymize on accepted spans.

Review speaker turns instead of a PDF canvas. Accepted names wipe in the transcript and can beep, silence, or anonymize the recording.

What you can upload

  • Microsoft Teams JSON, Slack export zip or JSON, WhatsApp chat text.
  • WebVTT, SubRip, or a generic speaker transcript.
  • Audio: WAV, MP3, M4A, OGG, FLAC, WebM. A zip may contain audio plus a caption file.
  • Video is rejected.

How review works

Northdocs parses the file into speaker turns, runs the same deterministic personal-data detectors as document review (including name gazetteer, narrative cues, and speaker display names), and opens a conversation review page instead of the PDF canvas. Click a timestamp to seek the recording. Accept a person to wipe that name in turn text and in speaker labels.

Accept or skip each identity once. Select a missed name in the transcript to mark every occurrence, or mark the speaker label. For recordings, choose beep, silence, or voice anonymize on accepted time ranges. Forensic light, standard, and strong shift vocal-tract length, pitch, and bandwidth and add masking noise. You can also anonymize a speaker across the whole file.

Allowance

Chats and transcripts count toward the workspace page allowance (one page per 15 turns). Audio duration uses a separate voice-minute allowance per user: 60 on Trial and Starter, 180 on Pro, 600 on Firm, unlimited on Enterprise. A captioned recording can consume both. The workspace voice pool is the per-user allowance times billed seats, with the same 5% soft cap as pages.
