Private by default. Frontier when you want it. Solair puts every kind of AI in your pocket, and keeps it private. Run powerful models fully on-device with no account and no internet, or connect Claude, ChatGPT, Grok and more when you want the frontier. Create images along the way, and keep every one in a gallery of your own. 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 model for each message: Fast for quick questions, Smart for deep reasoning, Vision for photos and documents. • A duress code and fully local processing mean no one can read your data, not even us. BRING YOUR FAVORITE AI • Connect Claude, ChatGPT, Grok, Kimi, DeepSeek, Mistral, and more in one tap, just paste your API key. • Send photos, PDFs, and videos, watch reasoning models think, and generate images where supported. • Real web research: cloud models search the web themselves and show every source they read. • With your permission, they can read your health, calendar, and weather, and chart it for you. • Tokens, estimated spend, and voice minutes tracked per provider. • Your memory and past chats stay on your device unless you choose to share them. CREATE IMAGES, AND KEEP THEM ALL • Generate images right in your conversation. Choose the quality, the shape, and how many, and see what each option costs before you create. • Every image you make lands in a gallery of your own: folders you name, favorites, and full-screen browsing. • Pinch to zoom, swipe to move through them, and see them in real HDR that glows on your display. • Jump from any image straight back to the conversation that created it. 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 on-device, only text ever leaves your phone, never audio, and live transcription types your words as you speak.
