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.

Verdict
The clearest difference is rating: microAI at 5.0 against Privacy AI's 4.8. microAI also leads on iOS requirement (16.4 vs 18.0). Privacy AI's advantage is ratings volume (20 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Privacy AI sells 3 in-app purchases, starting at $3.99 per 7 days and microAI sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
microAI holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Privacy AI has 20 ratings behind it against 2, so its average is the more settled of the two.
Privacy AI ships an update weekly, microAI every 9 days. The most recent releases landed on October 30, 2026 and October 28, 2026 respectively.
