Chat with an AI that lives on your phone, not in the cloud. Private AI is an offline AI chat app: open models like Qwen, Gemma and GLM run entirely on your phone — no server, no account, and after a one-time model download no internet at all. YOUR AI, YOUR DEVICE Cloud chatbots send every word you type to a data center. Private AI computes the answer on your phone's own chip: your chats, your photos and the models themselves stay with you. Uninstall it and everything goes with it. WORKS COMPLETELY OFFLINE Download a model once, then chat anywhere: • On flights, subways and trips abroad • In dead zones and on unreliable connections • Whenever you want answers that stay private Switch on airplane mode if you like — the app won't notice. THE LATEST OPEN MODELS, PHONE-SIZED • Qwen 3.5 (0.8B, 4B, 9B) — fast, smart and multilingual • Google Gemma 4 (E2B, E4B) — mobile-first quality, 140+ languages • GLM 4.6V Flash — flagship-class vision for high-end phones • Ministral 3 — compact, with a 256k context window • Bring your own: load any GGUF model by URL (Hugging Face links work) Models are 0.8–6 GB downloads. A "Fits your device" badge reads your phone's RAM so you know what will run well before you download, the catalog is searchable and filterable, and interrupted downloads resume where they stopped. BENCHMARK IT ON YOUR OWN PHONE Run the built-in benchmark on any downloaded model to see exactly how fast it loads and generates on your hardware — tokens per second, GPU or CPU — and pick the model that fits. CHAT WITH YOUR DOCUMENTS Attach a PDF, text or Markdown file to any chat and ask about it: the text is extracted and searched on your phone, the model answers from the matching passages and tells you which ones it used. Contracts, papers, manuals, notes: the files are never uploaded. UNDERSTANDS IMAGES Every model in the catalog supports vision. Add the optional image-support file, then snap a photo or pick one from your gallery: read documents, translate signs, decode menus, describe scenes. WATCH IT THINK Turn on thinking mode and reasoning models show their step-by-step working in a collapsible panel above the answer — great for math, code and anything worth double-checking. ASSISTANTS Start a chat with a ready-made assistant: Tutor, Writing Coach, Email Helper, Translator, Code Helper, Summarizer, Chef or Travel Planner, each with its own instructions and one-tap starters. An offline translator for your next trip, no signal needed. A REAL CHAT APP • Markdown that renders: code blocks with one-tap copy, tables and lists • Streaming answers with a live tokens-per-second readout • Switch models mid-conversation from the chat header • A system prompt per chat, plus Creative / Balanced / Precise / Thinking presets • Edit, regenerate, copy, select text — or have any answer read aloud (on-device TTS) • Search your chats, pin favorites, light and dark themes • Back up every chat and setting to a single JSON file, and restore anywhere PRIVATE BY DESIGN • Conversations and photos are processed on your device, never in the cloud • No account, no sign-up, no server • GPU-accelerated by llama.cpp — Metal on iPhone, OpenCL on Snapdragon Adreno PRIVATE AI PRO Free to use, with ads that never interrupt an answer (offline, none load). Pro removes all ads and adds your own custom assistants and accent colors. Choose monthly, yearly (with a free trial for new subscribers) or a one-time lifetime unlock. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel anytime in your store account settings.
