OnDevice LLM runs powerful open-source AI models 100% on your iPhone — no internet, no cloud, no account. Your conversations never leave the device. Every word you type, every reply you get, stays on your phone. There is no server to log it, no company to mine it, no account that can be banned. NEW: ASK ABOUT YOUR PHOTOS - Add a photo in chat and ask about it: what's the total on this receipt, when does this event start, what does this form ask for. - Runs on your iPhone like everything else. Works in airplane mode. - Pick "MiniCPM-V 4.7 1B (Vision)" in Models. WHAT'S INSIDE - A curated catalog of top open models: - llama.cpp / GGUF: Gemma 4 / Gemma 2, Llama 3.2, Qwen 2.5 / Qwen 3, Phi-4 Mini, SmolLM2, DeepSeek R1. - MLX (Apple Silicon native): Ternary Bonsai 1.7B / 4B / 8B. - Quick Start chips: tap a persona (Translator, Code Helper, Brainstorm, Email Writer, ELI5...) or a demo (Rock Paper Scissors, Click Counter, Snake, Calculator, Tic-Tac-Toe, Drawing Pad, Bouncing Ball, SVG illustration) to send the prompt with one tap. - Run mini-apps in chat: ask for a game, calculator, drawing pad, or SVG and tap "Run" to use the result right inside the chat — fully offline. - Markdown chat with code blocks, syntax highlighting, copy + share. - Attach PDFs, images, or text documents — the AI reads them locally. - Voice input via on-device speech recognition. - Persistent chat history with search. - Personal memory that learns useful facts about you (and stays on your phone). - Share Extension: send text from any app straight to your AI.
