Sapphire

Open-source framework for a self-hosted, voice-enabled AI companion that remembers you over time.

Desktopfreeglobal

Sapphire is a free, open-source framework for building a private, self-hosted AI companion with voice interaction, storytelling, and persistent memory across sessions. It's aimed at people who want an AI presence that remembers them over time and can be run entirely on their own infrastructure rather than a commercial companion-app cloud service.
