Here's how the top 10 compare in 2026.
What Makes a Good AI Note App
- AI auto-organization — Filing notes into the right folders without manual work
- OCR for screenshots — Reading text inside images
- Voice transcription — Converting recordings to searchable text
- Semantic search — Finding notes by meaning, not just keywords
- AI chat — Asking questions about your own notes
- Privacy — On-device or end-to-end encrypted, not training data for someone's LLM
1. Némos — Best On-Device AI Notes App
Némos is the first major notes app built entirely on Apple Foundation Models. Every AI feature runs locally on your iPhone — no cloud uploads, no third-party LLM, no data leakage.
AI features: - Auto-naming for screenshots, notes, voice memos, and links - Auto-filing into the right folder based on content - Smart Spaces (AI-curated topic collections) - On-device OCR for every image - On-device voice transcription - Semantic search across all content types - Title and summary generation
Why it's #1: It's the only AI notes app where the AI actually runs on your device. Every other app on this list sends your notes to an LLM provider for processing.
Price: Free (Pro $8.99/mo)

Price: $10/mo (in addition to Notion plan)

Strengths: Great for self-reflection, AI-driven prompts, privacy focused.
