What Ren is
A capable home AI that stays yours
Local-first memory
Every conversation, thread, and reminder lives in a SQLite file on your own machine. Nothing syncs to a cloud you do not control.
Cryptographic identity
Ren holds a persistent ed25519 keypair on-device and can present a signed identity card — a seam for a future trust network.
Whole-home control
Connectors, addressed by name, not by ID: Home Assistant, Philips Hue, HomeKit, Matter / Thread, Z-Wave locks, Sonos, Roku, ONVIF cameras, SmartThings, Hunter Douglas PowerView, HUUM sauna, Modbus TCP, IR blasters, Somfy RTS, relay boards, Enode (EV / solar), SmartCar, and Webhook.
Voice, optional
Server-side Whisper STT, Piper TTS, Silero VAD and wake-word — all CPU-only and entirely opt-in. Ren boots fine without them.
Safe tool system
A pluggable tool registry where side-effecting actions are gated off by default — Ren explains what it wanted to do instead of doing it blind.
Tiered models
Ren speaks in intent, not model IDs. Short asks route to a fast tier; planning and debugging route to a stronger one — automatically.
Ren Host
Claude for your home, running on your Mac.
Ren Host turns a Mac you already own into a private home AI. It requires a Mac with Apple silicon. Join the waitlist and we'll email you when it's ready. More about Ren Host.
Smart home
One assistant, every system
Ren ships connectors for the platforms you already run. Assign devices to rooms, group them into scenes, and write automations that reference them by name.
Your AI. Your hardware. Your data.
No hosted Ren accounts. No telemetry to us. Messages you send go to Anthropic's API. If you ask Ren to use a web page or a connected service, that request leaves your network too.
