About

OffNote AI

Read full description

OffNote AI turns your notes into a private knowledge base you can actually talk to. Write a memo, and OffNote AI quietly extracts the facts. Later, ask a question in plain language β€” who did I meet last Tuesday? what was that restaurant recommendation? β€” and get a direct answer from your own notes. Everything runs on your device. No data is sent to any server. No account required. HOW IT WORKS OffNote AI downloads a small AI model to your phone during setup. After that one-time download, it works completely offline. Your notes never leave your device β€” not even to generate answers. KEY FEATURES - Write and search notes with a clean, fast interface - AI automatically extracts key facts when you save - Chat with your notes: ask questions in natural language - Focus mode: ask about one specific note in depth - Conversation history across multiple chat sessions - Fully offline after the initial model download - No account, no subscription, no cloud storage - Choose from multiple on-device AI models in Settings WHY OFFNOTE AI? Most AI apps send your notes to a remote server to generate answers. OffNote AI runs the model locally, so your personal thoughts, plans, and records stay yours β€” always.
