Overview
ChatLab is a desktop app for looking back at your own conversations. You export chats from WhatsApp, LINE, QQ, Discord, Instagram, Telegram, iMessage or Google Chat, drag the files in and get word clouds, activity rankings, interaction heatmaps and time-of-day charts. If you connect an AI model, you can also ask questions about the history in plain words. Chats are stored and analysed on your computer, and it suits anyone curious about a friendship, a family group or a community chat over the years.
It works on chat files you already export and keeps them on your computer; the AI part is optional and only gets what a question needs.

Good to know
Look back over a long personal or group chat with charts of who talks when and about what. With a model connected, ask the built-in agent to search or summarise the history in plain words.
Limits
- ChatLab only reads exported files, so each chat app's export step comes first. The macOS desktop app is for Apple silicon Macs; Intel Macs can use the CLI web version.
- AI questions send the chat content they need to the model provider you set up. The app also sends anonymous usage statistics by default, which you can turn off in Settings.
