AI ON YOUR PHONE. POWERED BY YOUR DEVICES. Run private AI directly on your phone. Need more power? Connect your own computer and let it handle the heavy AI work while you keep using microAI from your phone. No sign-up. No cloud AI account required. Ask questions. Talk instead of type. Show AI a photo. Read a file. Work on a project. Save something for later. microAI brings local AI, your devices, and your private context together in one workspace. YOUR PHONE. YOUR COMPUTER. YOUR AI. Your phone can run compatible local AI models on its own. When you need more power, connect your own computer. Scan a QR code and your approved Mac or browser can run the model while you continue using microAI from your phone. That means you can move heavier AI work off your phone—reducing the load, heat, and battery use caused by demanding on-device inference. Use your phone when that is enough. Use your computer when you want more power. You choose where your AI runs. NO SIGN-UP. NO CLOUD AI REQUIRED. Local AI should not require another account. microAI can run compatible models directly on your devices without requiring a cloud AI account. Your computer can also become your own AI compute node. Open the microAI website on your computer, load a compatible local model, scan the QR code, and connect. No separate website account is required. DIFFERENT AI FOR DIFFERENT JOBS Not every task needs the same AI. microAI includes task-focused AI helpers: • Private Chat — Ask, write, plan, brainstorm, or talk. • Image Chat — Ask questions about photos and screenshots. • Voice Chat — Talk instead of typing. • Review Writer — Turn your experience into a clear review. • Photo Tagger — Create titles, descriptions, and keywords for photos. Choose which compatible model powers each job. Use a small model for quick everyday tasks, a vision model for images, or a stronger model running on your computer when you need more capability. TALK. SEE. READ. AI should work with more than a text box. Talk naturally with Voice Chat. Add a photo or screenshot and ask questions about what you see. Add a supported PDF, TXT, or Markdown file and ask questions about its contents. Use microAI for writing, research, documents, photos, ideas, and everyday questions. COME BACK WITHOUT STARTING OVER Your useful context should not disappear into old chats. Create Projects to keep related conversations, files, instructions, and context together. Save quick thoughts in Journal. microAI can remember useful context and bring it back when relevant. Memory Map gives you a visual way to explore your conversations, projects, journals, models, and memories. LOCAL AI WITHOUT THE USUAL SETUP You should not need to be an AI engineer to start using local AI. Find a compatible model, download it, and start. microAI keeps model discovery, downloads, switching, and resource management in one place. Advanced users can also import compatible GGUF models. Actual performance depends on your device, model, and connection. YOUR AI. YOUR DEVICES. YOUR DATA. When AI runs on your phone, compatible models process requests directly on your device. When you connect your own computer, the model runs on the computer you approve while you continue using microAI from your phone. Your model files stay on the device running them. You decide when a remote compute node is connected and used. Internet access may still be required for model discovery and downloads, purchases, ratings, app services, and certain system features. RUN AI YOUR WAY. On your phone when you want portability. On your computer when you want more power. No sign-up. No cloud AI account required. Your AI. Your devices. Your choice.

Lumey runs LLMs entirely on your iPhone. No servers. No logs. No telemetry. Chats, voice notes, and documents you import never leave the device. Pick from open-weight and proprietary models, side by side. A quick reasoner for everyday questions, a heavier model for code or long-form work; simply switch between them in a tap. Every model runs locally on Apple Silicon. Bring your own knowledge. Attach PDFs, plain text, or markdown directly to a chat. Lumey chunks and embeds the content on-device, so retrieval happens locally. Install curated knowledge packs for specific domains, or mention them mid-chat to scope a single reply. Organise your data into multiple vaults. Keep work and personal context separate. Turn on Travel Mode and every vault locks behind Face ID the moment the app backgrounds. WHAT'S INSIDE • Open-weight and proprietary LLMs running locally on Apple Silicon • Curated knowledge packs that plug into on-device retrieval • Manage multiple vaults to compartmentalize chats, documents, and voice notes • Voice notes transcribed entirely on-device • Travel Mode: biometric lock on backgrounding and vault hiding LUMEY PRO Unlock every model and every knowledge pack with a monthly or yearly subscription. The free tier includes the proprietary system model and some starter packs, enough to use Lumey as a private daily assistant without paying.
