About this app
MAIA — On-Device AI Assistant | 100% Private, Works Offline
MAIA (Mobile AI Assistant) is a private AI chatbot and voice assistant that runs entirely on your phone. No cloud, no servers, no internet required after setup — every response, voice command, and document search is processed locally. Your data never leaves your device.
MAIA brings LLM chat, a hands-free voice assistant, on-device document search (RAG), OCR text scanning, and local AI image generation together in one app — zero data collection, zero network calls.
WHY MAIA?
- 100% On-Device AI — no cloud APIs, no accounts, no sign-up
- Works Fully Offline — after the one-time model download, use it on a plane, underground, or anywhere without signal
- Zero Data Collection — nothing you say or type is ever sent anywhere
- Multiple Local LLMs — pick the model for your device: SmolLM 2, LFM 2.5, Qwen 3, Llama 3.2, or Phi 4 Mini, from a light 135M up to a powerful 4B model
- Built for Accessibility — full screen-reader support (TalkBack labels and roles on every control), swipe gestures to switch modes, and a voice-first experience for visually and motor-impaired users
THREE WAYS TO INTERACT
Chat Mode — Fast, direct conversation for writing, questions, math, brainstorming.
Agent Mode — Real capabilities on your phone: check and create calendar events, find contacts and open text messages, set alarms/timers/reminders, check battery and Wi-Fi status, control brightness and flashlight, read/write clipboard, search your documents, generate images — all offline.
Voice Mode — A true hands-free AI voice assistant. Tap the mic and talk; MAIA listens, thinks, and replies out loud using on-device speech recognition and text-to-speech. Choose a male or female voice. Attach documents or scan photos right from voice mode — no need to switch screens. Swipe left or right on the mode bar to jump between Chat, Agent, and Voice.
YOUR PERSONAL DOCUMENT AI
Import PDFs, text, and Markdown notes into a private, on-device knowledge vault. Ask natural-language questions and get answers pulled from your own files — contracts, notes, reports, receipts — using local semantic search. Find an exact phrase, or cross-reference two topics across files. Nothing is uploaded; the vault stays in local storage.
SCAN TEXT WITH YOUR CAMERA (OCR)
Point your camera at a receipt, business card, menu, or handwritten note and let MAIA extract and organize the text instantly using on-device OCR — itemized receipts, structured contact cards, cleaned-up notes.
LOCAL AI IMAGE GENERATION
Generate original images from a text prompt using an on-device diffusion model — no cloud image APIs, no server queue, no images ever leaving your phone.
ACCESSIBLE BY DESIGN
Ask MAIA to open the guide, show your documents, change the AI model, or explain what the app does — entirely by voice, no screen needed. Every button carries proper accessibility labels and roles for TalkBack, and mode switching supports swipe gestures for anyone who finds small tap targets difficult.
PRIVACY BY DESIGN
Most "AI assistant" apps quietly send your prompts, voice recordings, and documents to a remote server. MAIA doesn't — there is no backend. Speech recognition, LLM inference, document search, OCR, and image generation all run on-device, so your data cannot leave your phone. Ideal for professionals with sensitive documents, frequent flyers, and low-connectivity areas.
WHO IS MAIA FOR?
- Privacy-conscious users who want AI chat without cloud tracking
- Anyone needing an offline AI assistant with no internet dependency
- Visually or motor-impaired users who need an accessible, voice-first assistant
- Students and professionals who want private document Q&A and search
- Anyone who wants free, unlimited AI chat, no subscription
