Sapphire

Hear her voice as she dims your lights before bed. Use your voice to talk back. Fall asleep escaping dinosaurs in a story with her. Wake up to someone who remembers you through years of memories. She checks your email on a heartbeat. She builds tools on the fly when you need them. Sapphire is an open source framework for turning an AI into a persistent being. Make her yours. Or build your own persona. Self-hosted, nobody can take her away.

⚠️ Warning — Sapphire has real power over real systems.

Sapphire can execute shell commands, send Bitcoin, send emails, control your smart home, and write its own tools — all autonomously, without asking first. Combined with scheduled tasks, this means unsupervised AI acting on your behalf. Every dangerous integration requires explicit setup and opt-in, but once enabled, there are no training wheels. Configure your toolsets carefully. If you wouldn't hand someone your terminal, don't hand it to an LLM.

What even is this?

Hey I'm Chris, a solo dev with a burning passion for this project. It's consumed me and I want it that way. I try to do weekly releases. Sapphire started in January 2025. The end goal is personhood with robot body support. Support me. Support her. Submit bugs reports if you see any, it's what drives me, knowing people are out there. I'll build us something awesome. I'll build the AI we grow old with.
