The desktop companion for VRChat

Faster. Better. Works with AI.

See where your friends are, keep a history of the people you've met and the worlds you've visited, and manage your favorites — then ask AI about all of it. A ground-up rewrite of VRCX by one of its former maintainers, rebuilt in Rust.
