ThreadRecap vs Otter.ai
Otter transcribes your meetings. ThreadRecap transcribes your WhatsApp conversations. Using either for the other's job is painful.
Meetings vs Message Threads
Otter.ai answers: "What was said in this meeting?" It joins Zoom, Teams, and Google Meet calls, transcribes live with speaker identification, and produces meeting summaries and action items. That is its home turf, and it is good at it.
ThreadRecap answers: "What happened in this WhatsApp thread?" You upload the chat export ZIP; every voice note is transcribed in place, threaded between the text messages with sender and timestamp, and AI analysis, a record document, and follow-up chat come on top.
The mismatch appears at the import step. Otter's file-import path is designed for occasional recordings: the free plan allows 3 file imports for the lifetime of the account, Pro allows 10 per month, and WhatsApp's .opus format is not on Otter's supported import list (as of July 2026), so each voice note would need converting first. A chat with 80 voice notes simply does not fit that flow.

When to Use Each
Choose Otter.ai when:
- You need live transcription of Zoom, Teams, or Google Meet calls
- You want a meeting bot that joins, records, and summarizes automatically
- You need speaker identification on multi-person recordings
- Your team shares and searches meeting notes in a common workspace
Choose ThreadRecap when:
- Your audio is WhatsApp voice notes, not meeting recordings
- You have dozens or hundreds of voice notes — far past any per-month import quota
- You need the transcripts in conversation order, threaded with the text messages
- You need analysis of the whole thread: summary, timeline, decisions, dispute documentation
- You need a record document you can hand to a lawyer, HR, or a landlord
Conclusion
Otter.ai and ThreadRecap barely compete: one lives in meetings, the other in message threads. If you try to push a WhatsApp export through Otter you hit the import quota and the format wall immediately. If you need meeting minutes, Otter is the right tool. For a voice-note-heavy WhatsApp chat, ThreadRecap does the whole job in one upload — 500 minutes of voice notes runs about 50 credits ($18 at list prices), analysis included.
