Updated
WhatsApp’s own transcripts are phone-only
WhatsApp transcribes voice notes on Android and iPhone, in a short list of languages per device. WhatsApp Web has no transcript setting, so on a computer you either download the audio and upload it to another tool, or play it out loud. Kaption puts the transcript on the voice note itself.
How to transcribe a voice note
- 02
Open WhatsApp Web
Go to web.whatsapp.com and reload the page. Kaption appears inside your chats. Pin it from the puzzle-piece icon so it stays one click away.
- 03
Click transcribe on a voice note
The control sits on the voice message. The text appears under it, with the sender and time still around it.
- 04
Use the text
Copy it, summarize it, or translate it into your language. Long notes get a short summary so you know if the full text is worth reading.
The details
Dozens of languages
English, Spanish, Portuguese, French, German, Italian, Turkish, Chinese, Japanese and many more, in the language each note was recorded in. Live translation covers 36 languages.
Smart transcription
On Pro, transcription learns the names and brands you use, so the words that matter most come out right.
Follow along word by word
As a voice note transcribed in the cloud plays, each word lights up. Click any word to jump to that moment. On every plan.
A backup engine
If the main transcription engine is down, a backup engine takes over on its own, so your voice notes still turn into text. On every plan.
Rate a transcript
Give any transcript a thumbs up or down, and mark what was wrong. After a rating, a Share button lets you send that one voice note to Kaption to help improve transcription. It asks each time and never shares anything on its own. The privacy policy explains what happens to a shared voice note.
What leaves your computer
Only the audio you choose to transcribe, without your name, number or contacts. It is discarded once the text comes back, and it is never used to train AI models.
On the desktop app too
The Kaption desktop app for Mac (Apple silicon) and Windows 10/11 transcribes voice notes the same way, and on a Mac with macOS 26 it can transcribe on the computer itself. When the computer can't transcribe a note's language, the app sends that note to the cloud, unless you turned cloud fallback off or your plan has no cloud transcription; then it tells you the language can't be transcribed on this device.
On your phone
Kaption Transcriber for iPhone and Android transcribes voice messages on the phone. It is part of Pro.
Where it struggles
Background noise, crosstalk and unusual names. When a number or name really matters, play that part of the audio to check.
Plan and limits
Every account starts with 60 days of Business, unlimited. After that, Free continues with limits on voice notes. Lifetime local AI is one payment for unlimited transcripts and translation on your computer. Pro adds unlimited Turbo transcription in the cloud, smart transcription, unlimited summaries and translation, and the mobile app. Business adds a second WhatsApp number and call recording; Business Agent is coming in November.
