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. MORE TO LOVE • Build your own apps (beta): describe one in a sentence and Solair makes a real, working app that runs offline. Four finished apps are included. • Scheduled tasks: give Solair a job and a time, and the answer arrives as a notification, all on your device. • Personas: chat with friends, historical figures, or build your own. • Personal memory that learns your preferences, and document analysis with instant summaries. • Health intelligence, ask about steps, sleep, 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. • Models included: Qwen3 & 3.5, Llama 3.2, Mistral, Gemma 3, plus coding, lightweight, and vision models like Qwen VL and LFM2.5. WHY SOLAIR Most AI apps send everything to the cloud. Solair runs on your device first, so your private data stays private, and reaches for the cloud only when you choose. REQUIREMENTS • iPhone A14 or newer, iPad A12 or newer, Mac with Apple Silicon. iOS 26 or later. 500MB to 5GB per on-device model. Solair is free with no ads. Optional tips support development but never lock features. EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
