ChatLab: Chat Log Analysis Laboratory 174

What is ChatLab?

ChatLab is a free, open-source desktop application designed for analyzing chat history. It can store data exported from WeChat, QQ, Telegram, and others into a local database, and uses ai to help you find patterns out of messy conversations, with a strong emphasis on protecting your privacy.

ChatLab's analysis methods are simple:

• Write your own SQL queries to explore the data.

• Use local or online AI models to automatically analyze emotions, keywords, and relationships between people.

ChatLab Main Features
