The Spool app icon: a single thread that loops once, shading from indigo to amber

The best place to think out loud.

Jot a thought in a second. Spool keeps the moment around it, spools it into the right place, and brings it back right when you need it.

Join the beta See how it works

Write it down once. It finds you later.

Most notes are written and never seen again. Spool is built around the moment a thought becomes useful.

  1. Capture in a second

    Press ⌃⌥N from any app on your Mac, open the app on your iPhone, or just tell Siri. Type or dictate, then get back to what you were doing.

  2. It spools itself

    No folders, tags or titles to pick. Each thought is spooled into the right topic, with a note saying where it went and one tap to change it.

  3. Spool brings it back

    Before a meeting with the people in it, when you're back at the place, or when you open the page it was about. Or ask a question and get an answer from your own thoughts.

Context is captured, not typed.

You write the thought. Spool notes where you were and what you were doing, so it can tell when the thought matters again.

Sparing on purpose

One peek at the right time beats five at the wrong one. Each peek says why Spool brought it back, and leaves on its own.

Fixes its own filing

Move a thought or fix a title and Spool learns from it. You never have to organize.

Native on Mac and iPhone

Built with Apple's own tools. Quick capture, an edge drawer on the Mac, Siri and Shortcuts on the iPhone, synced through iCloud.

Your thinking stays yours.

There's no Spool account and no Spool server holding your notes. The privacy policy has the details.

Notes live in your iCloud

Your thoughts sync through your own private iCloud database. We can't read them.

Only what's needed leaves your device

To file a thought, Spool sends it with a little context (like the meeting title or place name) to a language model. It isn't used for training.

Your exact location stays put

The language model only ever gets a place's name, like “Office”, never your coordinates.

No trackers

No ads and no analytics SDKs. Diagnostics stay on your device.
