How to summarize a WhatsApp group chat (5 ways, with and without Meta AI)

You can summarize a WhatsApp group chat with WhatsApp’s own Meta AI features (message summaries for unread messages, a private side chat, or adding Meta AI to the group), by exporting the chat and uploading it to ChatGPT or Claude, or with a Mac app that reads WhatsApp as a linked device. As of 20 October 2026, WhatsApp’s built-in summaries cover only unread messages, are off by default, and work in English, Indonesian, Portuguese and Spanish in a limited set of countries.

Below are all five methods with exact steps, what each one can and can’t do, and the privacy cost of each. Every method sends your group’s messages somewhere to be processed, so the “where does it go” column matters as much as convenience.

Which method should you use?

Use message summaries if you’re on your phone and only need the gist of what’s unread. Use side chat if you want to ask questions about the group. Export to ChatGPT or Claude for one long, deep summary. Use a Mac app if you catch up on your computer and juggle several messaging apps.

Method	What it can summarize	Where it works	Where the messages go	Cost
WhatsApp message summaries	Unread messages in one chat	WhatsApp for iPhone and Android, limited countries, 4 languages	Meta’s Private Processing servers; WhatsApp says Meta can’t read them	Free
Side chat with Meta AI	Questions about the chat you’re in, including “what did I miss?”	Limited countries; still reaching accounts	Private Processing	Free
Meta AI as a group member	Only messages sent after it joins	Groups, limited countries; everyone sees it join	Standard version: Meta reads new messages. Private Processing version: Meta says it can’t	Free
Export to ChatGPT or Claude	Everything you export (WhatsApp Web lets you pick a date range)	Any phone or computer	Uploaded to OpenAI or Anthropic under your account’s settings	Free or your existing plan
Tera Chat on a Mac	The last 100 messages of any WhatsApp chat or group synced to the Mac	Mac with Apple silicon, macOS 15 or later	Stored on your Mac; the text being summarized goes to the AI provider you pick	Free with ChatGPT (through Codex) or a Claude or Grok API key; AI Plus $9.99/month

1. Use WhatsApp’s message summaries (unread messages only)

Message summaries are WhatsApp’s built-in “catch me up” button. Meta AI condenses the unread messages in an individual or group chat into a short summary that only you can see, and the summary disappears when you scroll away or leave the chat.

Turn it on first. The feature is off by default:

1. Open WhatsApp Settings.
2. Tap Chats > Private Processing.
3. Turn Private Processing features on. This switch also controls Writing Help (WhatsApp Help Center).

Then summarize a group:

1. Open the group with the unread messages.
2. Tap the {number} unread messages label above the first unread message. WhatsApp only offers this once there are “enough” unread messages and doesn’t say how many.
3. The first time, accept the terms and tap Continue.
4. Read the summary in the chat (steps from WhatsApp).

What it can’t do. It only summarizes what’s unread, so it won’t help with a thread you already scrolled past. WhatsApp’s how-to covers the Android and iPhone apps only. And Meta says it’s available only in some countries and may not reach every account there, even if friends in your country already have it. Our guide to WhatsApp message summaries and Writing Help covers availability and the “why don’t I have it” checklist in detail.

Privacy cost. The unread messages leave your phone, encrypted, for Meta’s Private Processing servers, which run inside a trusted execution environment. WhatsApp says neither Meta nor WhatsApp can read your messages or the summary. Meta’s engineering write-up says the servers keep nothing once the request is done, and is candid that researchers have bypassed trusted execution environments before and that unknown risks remain (Engineering at Meta, April 2025). Nobody else in the group is told you used it.

2. Ask Meta AI privately in a side chat

Side chat is the better tool for a busy group, because you can ask questions instead of getting one fixed summary. Meta AI uses messages from the chat you’re in for context, and only you see the conversation. Like the other Meta AI features, it’s limited to some countries and may not have reached your account yet.

On iPhone, per WhatsApp’s instructions:

1. Open the group.
2. Swipe left on the tab at the right side of the messages. Or tap and hold any message and choose Ask Meta AI privately.
3. Tap Continue if asked.
4. Type a question.

Questions to try:

• “Summarize what I missed since yesterday evening in five bullet points.”
• “Did anyone confirm the time and place for Saturday?”
• “Has anyone asked me something directly?”
• “List every date and plan mentioned this week.”

Side chat also runs on Private Processing, so WhatsApp says neither Meta nor WhatsApp can see your questions or the answers.

3. Add Meta AI to the group (for what comes next, not what you missed)

You can add Meta AI as a member so anyone in the group can ask it to summarize long threads or recap what the group decided (About groups with Meta AI). The catch: it can only read new messages, sent after it was added, so it can’t catch you up on a backlog.

To add it on iPhone: open the group, tap the group name, tap Add, select Meta AI, choose Meta AI or Meta AI with Private Processing, tap Done, then follow the prompts (Add members, Continue) (steps).

Two things to know before you do it:

• Everyone sees it. All members get a system message saying Meta AI was added (the standard version also posts a welcome message). Ask the group first.
• The two versions handle privacy differently. With standard Meta AI, WhatsApp says Meta can read new messages sent in the group and may use prompts, the messages you share and feedback to improve its AI. WhatsApp says the Private Processing version works without WhatsApp or Meta seeing the chat (About Meta AI with Private Processing in groups).

What about typing @Meta AI in the group? It doesn’t work for catching up. WhatsApp says only messages that mention @Meta AI, or that people choose to share with it, can be read by Meta (About AI experiences on WhatsApp). Meta AI doesn’t see the rest of the conversation, and your question is posted in the group for everyone to read.

4. Export the chat and ask ChatGPT or Claude

Exporting works for anyone, in any country and language, and gives the AI the whole conversation instead of just the unread part. It’s also the method with the clearest privacy cost: you hand everyone’s messages to another company.

Export from your phone (WhatsApp Help Center):

• iPhone: open the group, tap the group name, tap Export chat, choose Without media, then pick where to send it (for example Save to Files). You get a ZIP file.
• Android: open the group, tap ⋮ > More > Export chat, choose Without media, then pick where to send it.
• WhatsApp Web: click the chat’s menu, choose Export chat, then All messages or Custom date range, and click Export. A date range is the easiest way to summarize “everything since Friday.” Media isn’t included.

View once messages aren’t exported, and the web export also skips disappearing messages. If an admin has turned on Restricted chat, nobody can export the group at all.

Then summarize it:

1. If you got a ZIP file, unzip it (double-click it on a Mac) and find the text file inside.
2. Open the text file and delete phone numbers or anything you wouldn’t want to share. Find and replace makes this quick.
3. Upload it to ChatGPT or Claude with a prompt like this:

This is an exported WhatsApp group chat. Summarize what happened
since [date] in under 150 words. Then list:
1. Decisions the group made
2. Questions still open
3. Anything addressed to me ([your name])
4. Dates, times and places mentioned
If something is ambiguous, quote the message instead of guessing.

Privacy cost, in plain terms. In ChatGPT, new conversations can be used to train OpenAI’s models unless you turn off Improve the model for everyone under Settings > Data controls. A Temporary chat isn’t used for training but may be kept for up to 30 days (OpenAI Help Center). On Claude’s consumer plans, chats are used for training only if you allowed it in your privacy settings, in which case Anthropic keeps them for five years instead of 30 days (Anthropic, August 2025). Either way, the people in your group never agreed to this. Delete the conversation and the file afterwards.

Skip “WhatsApp summarizer” browser extensions. An extension that summarizes WhatsApp Web needs permission to read the page, which means every chat you open in that browser. Unless you know who makes it and how it handles data, the export route is safer because you control exactly what leaves your device.

5. Use a Mac inbox that can summarize any chat

If you catch up on a Mac, a unified inbox can summarize a WhatsApp group without exporting anything. Tera Chat is our app, so weigh this section accordingly. It’s a free Mac app that brings iMessage, WhatsApp, Telegram, Instagram and Tinder into one inbox and drafts replies in your own texting style.

How it works for a WhatsApp group:

1. Pair WhatsApp once: in Tera Chat, go to Settings → Messaging → WhatsApp → Pair device, then scan the QR code from WhatsApp on your phone (Settings → Linked Devices → Link a Device), the same way you’d link WhatsApp Web.
2. Open the group and press ⇧⌘S to Summarize its latest messages (up to the last 100).
3. For specifics, use Ask about this chat: “What time did we settle on for Saturday?” Answers draw on the last 50 messages in the chat.

The same keystroke works on Telegram and Instagram threads, and on iMessage once you grant Full Disk Access, so you’re not learning a different method for each app.

Privacy cost. Your messages are stored on your Mac and never uploaded to a Tera Chat server. The text being summarized goes to the AI you choose: your own ChatGPT account (through OpenAI’s Codex app), your own Claude or Grok API key, or a Tera Chat AI plan, which passes the text to Anthropic’s Claude through Tera Chat’s server without keeping it. Once AI is set up, some features run in the background, such as a summary after every 10 new messages in a chat. You can pause that in Settings → Pipelines.

Limits. Tera Chat needs a Mac with Apple silicon and macOS 15 or later; there’s no phone version. In a group, the AI is told which messages are yours but not which member sent each of the others, and for a backlog longer than 100 messages an export covers more. Tera Chat connects to WhatsApp as a linked device. WhatsApp says that when Restricted chat is on, people in that chat can’t use linked devices for it, which it describes as a way to keep unofficial clients and AI agents out of the chat (About restricted chat). Read the risks of all-in-one messaging apps before connecting any third-party client to WhatsApp. It’s free with your ChatGPT account (through Codex) or a Claude or Grok API key; AI Plus is $9.99/month or $99.99/year (cancel anytime).

How to get a better summary from any of these

Most bad summaries come from vague requests. Whatever tool you use, ask for the parts of a group chat that actually need you:

• Decisions: “What did the group agree on?”
• Open questions: “What’s still undecided?”
• Anything aimed at you: “Did anyone ask me something or mention my name?”
• Dates and logistics: “List every time, place and amount of money mentioned.”
• Tone check: “Is anyone upset or waiting on an answer?”

Then check anything important against the original messages. Meta’s help pages warn that AI output can be inaccurate, and the same is true of every model.

What to do next

For a quick phone catch-up, turn on message summaries. For a group you want to question, try side chat if you have it, or export a date range and ask ChatGPT or Claude. If you live on your Mac and the WhatsApp group is one of five busy apps, a unified inbox saves the most time.
