Read WhatsApp voice notes instead of playing them
Kaption adds a transcribe button to every voice note in WhatsApp Web. The text appears under the message, in the chat, in the language it was recorded in. Free and unlimited.
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 more than 90 languages.
Smart transcription
On Pro, transcription learns the names and brands you use, so the words that matter most come out right.
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.
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
Free: unlimited standard transcriptions, forever. Basic and Pro add unlimited summaries and translation. Pro adds smart transcription and the mobile app. See plans and prices

Is it really free?
Yes. Standard transcriptions are unlimited on the Free plan, with no card. Paid plans add summaries, translation, smart transcription and more.
Does it work on WhatsApp Business?
Yes. Kaption works with personal and WhatsApp Business accounts in WhatsApp Web, and in the desktop app.
Which browsers are supported?
Chrome, Edge and other Chromium-based browsers. Firefox and Safari are not supported.
Can I transcribe voice notes I sent?
Yes. Kaption transcribes any voice note in the chat, sent or received.
Stop playing voice notes out loud
Add Kaption to Chrome, open WhatsApp Web and click transcribe.
