Némos — Personal Knowledge Library App

Némos is a free personal knowledge library app for iPhone, iPad, Apple Watch, and web browsers. Save screenshots, links, notes, voice memos, PDFs, videos, places, books, and 15+ content types. Némos automatically names, organizes, and makes everything searchable using on-device AI. Your data never leaves your device.

Key Features

• Auto-save and auto-organize: Save a screenshot and Némos reads it, names it, files it, and extracts text — no manual tagging needed.
• Universal search: Find anything you saved with a keyword search across all content types, including OCR text from screenshots and transcribed voice memos.
• Voice transcription: Record voice memos that get automatically transcribed into searchable text, entirely on-device.
• Smart Spaces: AI-generated topic views (e.g., "Recipes", "Travel Ideas") that curate your saved content into browsable collections.
• Shared folders: Share any folder via link — no sign-up needed, syncs with iCloud for real-time collaboration.
• Daily routines: Build habit trackers with streaks, tracked from iPhone or Apple Watch.
• Native Apple sync: Two-way sync with Apple Reminders, Calendar, and Notes.
• Browser extension: Save links and articles from Chrome or Safari on any computer — syncs to your phone automatically.
• Apple Watch app: Check reminders, track routines, and record voice memos from your wrist.
• Speed reading: Read saved articles and ebooks with adjustable WPM overlay.
• Offline-first: Everything works without internet, syncs when connected via iCloud.
• 100% private: On-device AI processing using Apple Foundation Models. No cloud uploads, no data collection, no tracking.
