Fog: On-Device AI Notes

Requires a device with Apple Intelligence support to auto-organize notes.

Welcome to Fog, a notes app that organizes itself.

I struggle with organizing my notes, creating folders, figuring out what goes where, selecting things manually… the list goes on. So I built an app that aims to solve this.

Just write. Fog automatically groups your notes into smart collections called Clouds, so you always know where everything is, without lifting a finger.

Powered by Apple's on-device Foundation Models (on Apple Intelligence-supported devices), Fog understands what your notes are about and organizes them intelligently. Your notes are stored locally using SwiftData and synced seamlessly across your devices via iCloud — no third-party servers, no accounts, no data sharing.

Features

• Auto naming, notes become a canvas for your thoughts
• Auto grouping: canvases sort themselves into clouds as you write
• On-device AI: powered by Apple's Foundation Models, works fully offline
• Private by design: no third-party servers, your data stays in your ecosystem
• iCloud sync: seamlessly available across all your Apple devices
• Personal: choose a color theme, font, and even a personality for the AI
