About

Valdis

Read full description

Valdis is an AI companion that keeps one conversation going across your Mac and iPhone — at home, on a walk, and offline. Valdis is built natively for macOS and iOS — no Electron, no fake web UI. At home, chat in text or voice — with your Mac doing the heavy lifting (local Ollama by default, with LM Studio as a local-first alternative). You can also send images in chat — pick from Photos, the camera, files, or paste/drag-and-drop. Valdis passes images to supported multimodal models so you can ask about what you see. When you step outside, switch to Walk & Talk for hands-free voice. On a plane or without internet, use Apple’s on-device model (Foundation Models) on supported Apple Intelligence devices. Back online, switch back to your Mac — or to a cloud provider you choose — and keep going without resetting. WALK & TALK (HANDS-FREE VOICE) - Real-time voice chat with on-device speech-to-text (WhisperKit) - Spoken replies (hands-free) - A 3D avatar with lip-sync and animations (RealityKit) CONTINUITY THAT DOESN’T RESET Keep the same conversation going across iPhone and Mac, so you don’t have to repeat yourself. APPLE ON-DEVICE (FOUNDATION MODELS) When Apple Intelligence is available, Valdis can use Apple’s on-device model for fast, private replies — even offline. Requires Apple Intelligence to be enabled in Settings. MAC-POWERED INFERENCE Run bigger models on your Mac and talk to them from your iPhone: - macOS runs local Ollama by default (LM Studio is also supported!) - Vision models are supported (so you can send images) when the selected provider/model supports it - Your iPhone can use your Mac for inference while you’re out REAL-TIME iPHONE ↔ MAC SYNC Keep your conversation in sync between iPhone and Mac when your iPhone is using your Mac as the provider: - Your Mac app hosts the server your iPhone connects to - Works over local network, VPN, or Tailscale LOCAL FIRST - No Valdis cloud: Valdis doesn’t have its own servers — sync happens only between your devices when you use your Mac as the provider. - Your Mac app can act as your backend (and sync host) when your iPhone uses it as the provider. - Cloud providers are opt-in and used for inference only. - Zero telemetry: no analytics, no crash reporting.
