WhatsApp voice to text — transcribe every voice message in your export into searchable, summarized text.
Supported formats from WhatsApp exports (OPUS common). TXT, SRT, summarized bullets, action items — in one timeline.
Upload your chatHow it works
Export your WhatsApp chat with media so voice notes are included.
Upload the .zip. We detect voice notes (OPUS, etc.) and transcribe them.
Get transcripts merged into the chat timeline — then run analysis for summaries and action items.
What you get
Transcripts and analysis, not just raw audio files.
Supported formats from WhatsApp exports
WhatsApp exports use specific formats. We handle them.
- •OPUS — common for WhatsApp voice notes (PTT-*.opus). We transcribe these.
- •M4A — some devices or older exports may use this. Supported when present.
- •MP3 — less common in WhatsApp exports; we support it when present.
Transcript outputs
You get more than plain text.
- •TXT — full transcript merged into the message timeline.
- •SRT — not exported yet; timeline is available in the analysis view. (Future: SRT export.)
- •Summarized bullets — run General Summary or Meeting Recap to get key points from the transcript.
- •Action items — run Meeting Recap to extract tasks and deadlines from voice notes.

Frequently asked questions
In WhatsApp: open the chat → ⋮ (menu) → Export chat → choose “Include media”. The .zip will contain voice note files (usually PTT-*.opus). Upload that .zip to ThreadRecap; we detect and transcribe them.
Yes. After transcription, we merge voice text into the timeline and run analysis. Use General Summary for key points, or Meeting Recap for decisions and action items. The transcript is the input — you get structured output (summary, decisions, tasks) on top.
We support OPUS (most common for WhatsApp voice notes), M4A, and MP3 when they appear in your export. WhatsApp typically uses OPUS for voice messages.
We merge transcripts into the chat timeline and show them in the analysis. A dedicated SRT export is on our roadmap; today you get the full transcript in the analysis output and can copy it.
Audio is sent only for transcription and is deleted after processing. We don’t store your voice notes. See our Privacy Policy.
Today we process all voice notes in the export you upload. To transcribe only a subset, export a chat that includes only the messages you want, or use a trimmed date range when exporting from WhatsApp.
