Offline AI: Local LLM Chat

Offline AI chat that runs entirely on your phone. MyAI is a private AI assistant powered by local LLM models — download a model once, then chat offline with no account, no subscription, and no internet connection needed. Nothing you type ever leaves your device.

HOW IT WORKS
Pick a local LLM from the curated catalogue or search HuggingFace live. Download it over Wi-Fi, load it, and start chatting. Everything after that download runs on your phone's own processor — no server, no API key, no cloud.

WHAT YOU CAN DO
• Offline AI chat with any GGUF model — small local LLM models that run on any phone, larger ones on high-memory devices
• Image generation — create images from a text prompt, generated on-device with no internet connection
• Vision — attach a photo and ask about it. Read text in images, describe scenes, work through charts and documents, all on-device
• Arena — put two AI models in a debate, each with its own persona, and watch them argue it out
• Personas — give your offline AI assistant a consistent character, or write your own system prompt
• Response modes — LaTeX renders maths properly, Code highlights syntax, Concise trims length, plus step-by-step, ELI5, formal and email
• Documents — import a PDF, Word file or plain text and ask questions about it offline
• Voice — speak your question and hear the answer, transcribed on-device
• Web search — optional DuckDuckGo lookup when you need current information. Off by default
• Discover — AI news and trending open-source LLM models, updated through the day
• Stats — tokens, speed, and an honest read on what your device can actually run

A PRIVATE AI CHATBOT, ACTUALLY PRIVATE
Your conversations are processed entirely on your phone. There are no servers to breach, no databases to leak, and no company logging what you ask. No account. No analytics. No crash reporting. No third-party tracking of any kind.

Three things use the network, and only these:
• Downloading model files from huggingface.co
• Web search queries to DuckDuckGo, when you switch it on
• The Discover news feed

Turn off web search, put the phone in airplane mode, and your private AI chat still works. That is the point of it.

WHY RUN AI OFFLINE
Cloud chatbots send every message to someone else's server. A local LLM does not. That means your notes, your work, your health questions and your half-formed ideas stay on the device — useful on a plane, on bad signal, abroad without data, or simply when you would rather not hand your thinking to a company. No subscription, no rate limits, no usage caps.

WHAT YOUR PHONE CAN RUN
Every model shows how much memory it needs and whether it fits your device before you download anything. Compact offline AI models run comfortably on most phones. Larger ones need more memory and generate more slowly. The app tells you which is which rather than letting you find out after a four-gigabyte download.

OPEN MODELS, YOUR CHOICE
MyAI supports the open-source GGUF ecosystem — Llama, Gemma, Qwen, Mistral, SmolLM and more. Swap models freely, keep several installed, and pick the right one for the job.

BEFORE YOU DOWNLOAD
Responses from any AI model can be inaccurate, incomplete or inappropriate, and you are responsible for the models you download and use. Do not rely on AI for medical, legal, financial or safety decisions.

Requires a 64-bit Android device. Models range from roughly half a gigabyte to several gigabytes each.
