iApp ChindaGo vs Valdis

Requires iPhone 12 or newer. Models run on the device's graphics processor, and earlier iPhones cannot run them. ChindaGo is your daily life & emergency AI companion — an on-device AI assistant from iApp Technology. Answers are generated on your iPhone, so your conversations, your files and your questions do not leave the device. • Offline-first: works without internet, keeping your data private • No round trip: your question is answered on the phone, not sent to a server • Multilingual: fluent in Thai and English, interface included • Practical AI: helps with daily tasks, planning, and emergency guidance • Point your camera at it — photograph a receipt, a form, a label or a page of a contract and ask about it without leaving the app • Ask about your documents — attach a PDF, a text file or a photo, and text is read out of images as well • Choose your model — pick an open model in a size that fits your phone, or add any MLX model from Hugging Face or a folder on your device. Each one shows what it costs in space and memory before you download it • Decide what it is allowed to do — web search, Wikipedia lookups and reading your folders are each a switch, each asks before it runs, and one "Fully offline" switch closes all of them at once Nothing is uploaded unless you switch on a tool that needs the network — and when you do, only what that tool needs is sent. Stay connected, even when you're not. Wherever you go, ChindaGo is always ready to assist.

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.
