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 — who did I meet last Tuesday? what was that restaurant recommendation? — 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 — 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 — always.

Verdict
The clearest difference is in-app purchases: OffNote AI at none against Bookmarx AI's 1. OffNote AI also leads on iOS requirement (15.1 vs 26.0). Bookmarx AI's advantage is device support. On price there is nothing between them.
