Make Chat AnalysisSimple

A local-first analytics platform designed for chat data, combining visualization and AI Agent capabilities

Local Analysis, Privacy First

Chat history and settings stay in your local database. All analysis runs locally — it works even offline.

* AI features are the exception. If your hardware supports it, local models are recommended.

Incredibly Easy to Use

No Python, no command line needed. ChatLab packages all the complexity — just import your chats and go.

Standardized Chat Format

Through a standardized data abstraction layer, we smooth out differences across chat platforms. We support mainstream global chat apps and allow custom adapters for any chat software.

Stream Processing, Extreme Performance

With stream computing and multi-threaded parallel architecture, ChatLab remains smooth and responsive even with millions of chat records.
