The goal

Make it easy to return to a thought, even when the internet drops or a note is moved.

The approach

Writing stays at the center of the app. Autosave and recovery are close at hand; notebooks and search support finding your way back to older work.

What it includes

  • Rich notes, equations, and nested notebooks
  • Local saving, search, and version recovery
  • A multilingual welcome experience with a sample notebook walkthrough
