What is Wiz.chat?

Wiz.chat allows users to converse with AI-generated characters that can be customized to fit a wide range of roles, from historical figures to fictional personas. The service runs locally on a computer with a GPU, eliminating the need for downloads, cloud accounts, or sign‑ups.

Interaction occurs entirely within the latest Chrome browser, keeping all data on the device and preserving privacy. Users can create and explore scenarios for writing, gaming, education, or research purposes without external data collection. Because the application is self‑hosted, it supports offline operation and can be integrated into personal projects that require strict data control.
