Transcribe voice notes, summarize long chats and reply with AI — without leaving WhatsApp Web. Free to install on Chrome and Edge.
Just a quick update on the Q4 roadmap: we've successfully finalized the design phase and are moving smoothly into development. The team is on schedule, and we're still targeting a mid-November launch. I'll share the updated timeline deck with everyone later today.
The original minimalist tool. Transcribe voice notes without leaving WhatsApp Web. Private, fast, and secure.
Translate messages in real-time, breaking language barriers effortlessly.
Join thousands of users who are already saving hours every week with the highest-rated WhatsApp extension.
"Functional and fast to read; the transcription is honestly better than WhatsApp's own feature."
"Works like a charm and is super easy to install"
"I've tested it for several days and it's great, especially how the audios are transcribed automatically"
"Excellent tool, saves me so much time every day."
"Works well for me, exactly what I needed"
Three clicks and the transcribe button is there, on every voice note in WhatsApp Web.
Go to the Kaption AI page in the Chrome Web Store. On Microsoft Edge, open the Edge Add-ons listing instead.
chromewebstore.google.comConfirm "Add extension" in the dialog your browser shows. It downloads in a couple of seconds and there is nothing to configure.
Reload WhatsApp Web and Kaption appears in your chats. Pin it from the puzzle-piece icon in the toolbar to keep it one click away.
web.whatsapp.comInstalling is free, and it works on Chrome, Edge and other Chromium-based browsers.
What people ask us before installing Kaption AI.
Yes. Installing the extension is free and you can start transcribing voice notes right away, with no credit card. The optional Basic and Pro plans add unlimited transcriptions, unlimited translation sessions, smart transcription and more scheduled messages.
The extension only runs on WhatsApp Web and works with the chats you already have open there. Your history stays in encrypted storage on your own device — no message content is kept on Kaption's servers. Audio you choose to transcribe is sent for processing and discarded as soon as the text comes back, and your conversations are never used to train AI models.
Kaption adds its features to web.whatsapp.com, so it works with whichever account is signed in to that tab. It is a browser extension rather than an integration with the official WhatsApp Business API, so it does not connect to Cloud API numbers.
Yes. Kaption AI is published in the Microsoft Edge Add-ons store, and the install button on this page switches to "Add to Edge" when you browse in Edge. Other Chromium-based browsers that can install from the Chrome Web Store work too.
