Summaries · Groups and voice notes
Catch up on any WhatsApp chat in a few lines
Kaption summarizes long voice notes and whole conversations in WhatsApp Web and the Kaption desktop app, so a day of group messages becomes a short list of what was decided and what needs you.
Groups move faster than you can read
A busy group can post hundreds of messages and a dozen voice notes while you are in a meeting. Scrolling back and replaying audio is how an hour disappears. A summary tells you what happened, then you open only the messages that matter.
How to summarize a chat
- 02
Open the chat or group
Open WhatsApp Web, or the desktop app, and go to the conversation you want to catch up on.
- 03
Ask for a summary
Summarize the conversation, or a single long voice note. A voice note gives you the choice: the summary, or the full transcript.
- 04
Act on it
Reply, set a reminder on a message, or schedule a follow-up, without leaving the chat.
The details
Voice note summaries
Read the point of a five-minute voice note in a few seconds, and open the full transcript when the detail matters.
Conversation summaries
Turn a day of group chat, or a long thread with a client, into short, actionable points.
From your AI assistant
With the Kaption MCP server, Claude, ChatGPT or Cursor can summarize a chat for you, for example “summarize today’s Sales group”.
Where it can slip
AI summaries can miss sarcasm, inside jokes and who was replying to whom. Check the messages before you act on anything important.

Questions
Can it summarize a WhatsApp group?
Yes. Open the group in WhatsApp Web or the desktop app and summarize the conversation.
Which languages?
Kaption summarizes chats in the languages it transcribes, including English, Spanish, Portuguese, French, German, Italian, Turkish, Chinese and Japanese.
Are my messages sent to a server?
Only the text you choose to summarize, without your name, number or contacts, and it is never used to train AI models. Your chat history stays in encrypted storage on your computer.
Does it work on my phone?
Summaries run in WhatsApp Web and the desktop app. For voice messages on a phone, there is Kaption Transcriber, part of Pro.
