Notes

Notes are memory in progress.

Most notes aren't documents. They're fragments.

Half a sentence. A decision. A name. A question. Shelf treats fragments as legitimate memory rather than unfinished writing.

Free. macOS 14 and later, Apple Silicon and Intel. No account.

Five fragments written weeks apart. Individually thin; together, an argument you didn't know you'd made.

You don't write notes to keep them tidy.

You write them to stop something from disappearing.

Which means the value of a note is almost never in its formatting. It's in whether the thought inside it can be found again when you need it.

  • One line, no title, no folder
  • A decision and the reason behind it
  • A question you couldn't answer yet
  • A name, a number, a phrase to keep

Two fragments, six weeks apart.

Neither note mentions the other. They're about the same thing.

Note
“Search assumes you remember words.”
  • One line, written at night
  • No title
  • Beside two essays on memory

Written in November

Both fragments argue that retrieval starts from context, not keywords, so Shelf keeps them within reach of each other.
Note
“The unit is the moment you decided to keep it.”
  • Written after a user conversation
  • Part of a longer scratch note
  • Beside the interview clip

Written in February

No system to maintain.

Every note-taking method eventually asks for upkeep: tags to prune, links to maintain, a structure to keep honest. The upkeep is what people abandon, not the notes.

Shelf asks for nothing. Write the fragment. Let the connections be found later.

Notes are the most private thing you keep.

Unfinished thinking, worries, judgements about people, things you'd phrase differently in public. Shelf keeps notes on your Mac, reads them there, and never uploads them.

No account. Nothing trained on your thinking.

A fragment is not a failed note.

It's how thinking actually arrives.

Write the fragment. Keep the thought.

No titles, no folders, no upkeep. Just the line, and a way back to it.

Next thought

Notes accumulate faster than any system for them. Meaning is the only thing that scales.

Search isn't memory

Shelf V3 is out now

Shelf V3 is the current build. Shelf does not use automatic updates, so download the latest build here and install it over your current version.

This is intentional. Shelf is built around a local-first, privacy-focused philosophy. An automatic updater requires additional background processes, network connections, update infrastructure, and another system with permission to modify the app. We prefer to keep Shelf’s network footprint and background activity as small as possible.

Manual updates keep the process explicit: Shelf only checks the internet when a feature actually needs it, and you decide when a new version is downloaded and installed.
