Rexclaw Companions

Anime-style 3D companions you talk to out loud. They answer in real time with their own voices, faces and body language, and they remember you across days, weeks and whole ongoing conversations. Free, open source (MIT) and self-hosted, for Windows, macOS and Linux.

Bring your own AI: connect an xAI key for Grok Realtime, OpenAI, Claude, ElevenLabs or Fish Audio, or run models on your own computer with no key at all.
