Auto-Organized
Notes sort themselves into smart collections called Clouds as you write — no folders, no filing, no effort.
Clear your Fog.
If you've ever abandoned a notes app because keeping folders tidy felt like a second job, Fog was built for you. Just write. Fog automatically groups your notes into smart collections, so you always know where everything is — without lifting a finger.
Live Cloud Grouping
As you write, related notes are grouped into Clouds in real time — the UI updates instantly so your notes are always organized without any manual sorting.
