local-ai-notes turns your notes into a structured knowledge system that organizes itself. Type anything — your notes are automatically clustered by meaning using machine learning that runs entirely on your iPhone. No cloud, no API calls, no tracking. KEY FEATURES - Automatic Semantic Clustering Notes group themselves by topic using on-device embeddings. No manual folders, no manual tagging. - Slash Commands /remind for reminders, /ask to query your notes, /calendar for events, /tag for tags, /lock for biometric protection. - Voice Input Speak naturally — local speech recognition transcribes and routes your input to the right action. - Knowledge Graph See how your notes connect. Force-directed visualization of semantic relationships. - Smart Mode (Optional) Download an on-device AI model (Gemma 3 or LFM2.5) for natural language answers grounded in your notes. PRIVACY-FIRST Everything runs on your device. We don't have servers. We don't track. We don't analyze. We can't see your notes — even if we wanted to. Your data is encrypted at rest, biometrically locked, and never leaves your iPhone. REQUIREMENTS - iOS 17 or later - iPhone XS or newer recommended - Smart Mode requires additional 1-3 GB free storage
