How to Transcribe WhatsApp Voice Notes (and Get a Summary)
Someone sent you a 4-minute voice note. You're in a meeting, on the bus without headphones, or you just don't have time to listen to the whole thing to find the one detail you need.
WhatsApp's own transcripts help a little, but they only work in some languages and on some phones, you have to open each note one by one, and they don't summarize anything.
An AI connected to your WhatsApp can do it for you. You just ask:
- "What did Maria say in her last voice note?"
- "Summarize the voice notes in the family group from today."
- "Transcribe the audio my client sent this morning and list what he's asking for."
This guide shows how to do it with WhatsApp MCP, using Grok Bot as the example. It works the same in ChatGPT, Claude and Muse. No install, no coding, about two minutes.
Step 1: Connect your AI to WhatsApp
- Go to wa-mcp.com and pick your AI under Which AI do you use?.
- Click Get my WhatsApp key and follow the steps on the page. For Grok Bot, one click opens it with the setup prompt ready to send.
- Link your WhatsApp by scanning a QR code or typing a pairing code, just like linking WhatsApp Web.
Step-by-step guides for each AI: Grok Bot, ChatGPT, Claude and Muse.
Step 2: Ask for the transcript
Name the person or the group, and which voice notes:
- "Transcribe Maria's last voice note."
- "What do the 3 audios Carlos sent yesterday say?"
- "Transcribe the voice notes in the Work group from this morning."
The AI finds the notes in the chat and turns them into text, word for word, in whatever language they were spoken. It works for notes in groups and forwarded ones too. Long notes can take a minute; if the AI says they're still processing, ask again shortly.
Step 3: Get the short version
A transcript of a 5-minute ramble is still long. Ask for what you actually need:
- Summary: "Summarize it in 3 bullet points."
- Just the action items: "What is she asking me to do, and by when?"
- Details: "What address and time did he say?"
- Translation: "Translate it to English."
- A reply: "Write a short reply saying yes to Friday. Show it to me first."
Step 4: Find it again later
Once a voice note is transcribed, it stays with the chat:
- When the AI reads that chat again, it sees the text instead of just [voice note], so group summaries include what was said.
- Searches find it: "Find the voice note where my landlord mentioned the deposit."
Frequently asked questions
Does WhatsApp transcribe voice notes by itself? WhatsApp has a transcript option on some phones and in some languages, but you turn it on per device, open notes one at a time, and it doesn't summarize, translate or search them. An AI connected to your WhatsApp does all of that from one request.
Which languages does it understand? Most languages, including Spanish, Portuguese, English, Hebrew and Cantonese. It writes the transcript in the language that was spoken, and the AI can translate it.
How long can a voice note be? Up to 10 minutes per note, and you can ask for several notes at once.
Does the sender know I read the transcript? No. Transcribing doesn't play the note on your phone or send blue ticks. The note stays unplayed in WhatsApp.
Is it free? Transcription is a Pro feature (from US$4 a month, billed yearly), along with opening the photos and files you receive, sending files and scheduling messages. You can try it during the 1-hour free trial. Notes that were already transcribed stay readable on any plan.
Does it work with WhatsApp Business? Yes. It connects to the number you already use, on regular WhatsApp or WhatsApp Business.
Is my data private? WhatsApp MCP stores your messages and transcripts only so your AI can read and search them, and deletes them automatically after 90 days. Your data is never sold or used to train AI models. The audio is transcribed by an AI provider (Google) under terms that don't let it train on your data, and messages your AI reads are also processed by its provider (for example xAI for Grok Bot) under its own privacy policy.
Got a voice note you don't have time for? Connect your AI to WhatsApp and ask it what the note says. Setup is free and no credit card is needed.
