The Open Architecture for Building Personal AI Systems
Designed for individual developers. Infinitely extendable via tools. Your Memory is the platform.
Your Memory is the platform. Everything else is swappable.
Four Components
Your Memory
The platform. Your data, config, preferences, and conversations. Everything else depends on it — it depends on nothing.
Agent Loop
The agent loop. Sends messages to the model, executes tool calls, repeats until done. New capabilities arrive by adding tools.
Gateway
The front door. Web app, CLI, mobile app, Discord bot — any interface connects through it. Start on one, continue on another.
Auth
Controls access to your system. Independent of every other component — swap anything else, auth doesn't change.
Two APIs
Gateway API
How your interfaces connect to the system. Any client that speaks the protocol works — web app, CLI, mobile app, Discord bot.
Model API
How the agent loop connects to AI models. Swap providers with a config change — no code changes required.
Runs on a laptop. Use any model, tool, or interface.
