About this app

Chat with AI that has nowhere to send your data. Personal LLM runs open AI models entirely on your phone — there is no server, no account, and after a one-time model download it works with no internet at all.

YOUR AI, YOUR DEVICE
Cloud chatbots send every word you type to a data centre. Personal LLM computes the answer on your phone's own chip: your chats, your photos and the models themselves stay with you. Uninstall it and everything is gone — nothing was ever anywhere else.

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, and interrupted downloads resume where they stopped.

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.

A REAL CHAT APP
• Markdown that renders: code blocks, 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 — or have any answer read aloud (on-device TTS)
• Search your chats, pin favourites, light and dark themes
• Back up every chat and setting to a single JSON file, and restore anywhere

PRIVATE BY DESIGN
• Conversations and photos never leave your device
• No account, no sign-up, no server
• GPU-accelerated by llama.cpp — Metal on iPhone, OpenCL on Snapdragon Adreno
• Free to use, supported by ads — ads never interrupt an answer, and offline none can load

Your questions are yours. Keep them that way.
