Features
Valdis at a glance
Mac-hosted AI, with iPhone in your pocket.
Walk & Talk
Talk to your Mac-hosted Ollama or LM Studio while you’re out — from your iPhone.
Voice chat
Speak naturally (on-device STT via WhisperKit) and get answers back — hands-free.
Spoken replies
Apple Text-to-Speech for when you don’t want to stare at a screen.
3D avatars
RealityKit avatars with lip-sync and animations (3 today, more coming).
Models
Choose where your model runs (local or cloud) — and switch anytime.
macOS default: Ollama
Valdis runs Ollama on your Mac by default (or LM Studio if you prefer) — your Mac becomes the inference box for your iPhone.
iOS default: your Mac
On iPhone, Valdis connects to the Valdis Mac app (built-in WebSocket server) and reuses the same provider settings — via Tailscale, VPN, or your local network.
LM Studio
Run local models in LM Studio and connect through its local service endpoint.
Cloud providers
OpenAI, Grok, OpenRouter, DeepSeek, and Claude — if you’re okay sending prompts to the cloud.
Apple Foundation Models
Still taming the Apple llama — on-device LLM on Mac and iPhone via Apple Foundation Models (on iOS, this is currently the only true on-device option; requires Apple Intelligence).
Sync & Memory
Your conversations follow you across devices — without iCloud.
Real-time iPhone & Mac sync
Live conversation sync to your Mac via its built-in WebSocket server — over Tailscale, VPN, or the same network. No iCloud required.
Conversation memory
Rolling summaries + chat context so you get continuity without huge prompts.
Core & Privacy
Native Swift, local-first by default, and privacy-first.
Local-first by default
Your data stays on your devices by default — the app works even when you’re offline.
Privacy-first
Nothing leaves your devices unless you explicitly enable a cloud provider. Zero telemetry.
Native Swift app
Built natively for macOS and iOS — no Electron, no fake web UI.
Tight Apple integration
Uses Apple-native building blocks like RealityKit (3D avatars) and Apple Foundation Models for a truly integrated experience.
Same UX on macOS + iOS
Shared UI patterns and shared state — consistent across devices.
