Kaption AI is a browser extension for WhatsApp Web that transcribes voice notes into text, summarizes long chats and drafts AI replies. It installs from the Chrome Web Store or Edge Add-ons and runs on web.whatsapp.com, with a transcribe button on each voice note. The company also offers a desktop app for Mac and Windows that keeps several WhatsApp numbers side by side, and a phone app that delivers voice-note transcripts on iPhone and Android.
Beyond transcription, Kaption adds live translation, scheduled messages, reminders, chat snoozing, a Kanban board built from WhatsApp labels or Lists, call recording with transcripts, and exports of contacts, group members and chats as CSV, JSON or web pages. Privacy mode blurs names and messages, and a screen lock protects WhatsApp Web with a PIN or password. An MCP connection lets ChatGPT, Claude or Cursor search chats and transcripts with user approval.
The site describes use by lawyers, clinics, real estate agents, import and export businesses and sales teams whose work runs through WhatsApp.
