Private by default. Frontier when you want it.

Solair puts real AI on your iPhone, iPad, and Mac, and keeps it private. Run powerful models fully on-device with no account and no internet, or connect your favorite cloud provider when you want the frontier. Your call, every time.

RUN AI ON YOUR DEVICE • 100% on-device models, no account, no sign-up, no tracking. Once a model downloads, everything works offline. • Your conversations, photos, health data, and documents are processed locally and never leave your device. • Auto Mode picks the right on-device model for each message: • Fast for quick questions • Smart for deep reasoning • Vision for understanding photos and documents • A duress code and fully local processing keep your data yours, no one can read it, not even us.

BRING YOUR FAVORITE AI (NEW) • Connect Claude, ChatGPT, Grok, Kimi, DeepSeek, Mistral, and more in one tap, just paste your API key. • Send photos and PDFs to vision-capable providers, watch reasoning models think, and generate images where supported. • Real web research: cloud models search the web themselves and show every source they read. • Track tokens, estimated spend, and voice minutes per provider. • Your memory and past chats stay on your device unless you choose to share them with a provider.

TALK TO IT • Live voice conversations with ChatGPT and Grok, interrupt anytime, and the whole talk lands in your chat as a transcript. • Every other provider gets a voice through Solair's on-device voice pipeline, only text ever leaves your phone, never audio. • Live transcription types your words as you speak, plus adjustable speaking speed and faster replies.

MORE TO LOVE • Personas, chat with friends, historical figures, or build your own. • Personal memory that learns your preferences and interests for more relevant answers. • Document analysis, upload PDFs and text for instant summaries. • Health intelligence, ask about steps, sleep, heart rate, and workouts from Apple Health, all on-device. Informational only, not medical advice. • Connect to your own server (Ollama and more) securely over Tailscale. • A beautiful Liquid Glass interface for iOS 26, with an engine switcher, sidebar search, and customizable themes.

ON-DEVICE MODELS INCLUDED • Language: Qwen3 & 3.5, Llama 3.2, Mistral, Gemma 3, and more, plus coding and lightweight models for older devices. • Vision: Qwen VL and LFM2.5 for images, documents, and charts.

WHY SOLAIR Most AI apps send everything to the cloud. Solair runs on your device first, so your private data stays private, and lets you reach for a cloud provider only when you choose. You're always in control of what leaves your phone.
