Overview

Collections let you group related notes together—similar to tags, but with more structure. A note can live in multiple collections at once.

​
How to add a note to a collection

  • Click Organize in an open note and type a collection name. Select an existing collection or create a new one.
  • Or type # followed by the collection name while editing. Pick from suggestions or create a new collection.

​
Auto‑Organize

  • Click Organize and choose Auto‑organize from the menu.
  • Mem will try to add the note to an existing collection, or create a new one if it doesn’t find a good fit.
  • You can also multi‑select notes and choose Auto‑organize to file many notes at once. See: /features/bulk-actions
