The Transom app icon: a glowing fanlight window hanging from the notch

Your notch, finally useful.

Transom turns the notch into a small island of the things you reach for, and brings private writing help to every app on your Mac.

The island

A little island at the top of your screen.

Hover the notch and it opens. Swipe or scroll between pages for the things you check all day, like your next meeting, a live system monitor, Keep Awake and a shelf for files, then let it fold away again.

Transom Type

Suggestions as you type, in any app.

Grey text appears after your cursor. Tab takes the next word; carry on typing to ignore it. A language model running on your Mac does the thinking, so nothing you write is sent anywhere.

  • Stays out of password fields, terminals and Secure Input
  • Per-app switches, and instructions in your own words
Writing Tools

Say it another way.

Select some text and a small button appears beside it. Pick a tone, or tidy, summarise and pull out the key points. See the result next to your original, edit it, and put it back in one click.

  • It checks its own work: numbers and addresses that change are flagged
  • Undo with ⌘Z, like any edit you made yourself
Proofread

Proofreading with receipts.

Every correction is shown, struck through in red and added in green, before anything changes. It fixes spelling, grammar and punctuation, and leaves what you meant alone.

  • Numbers, links and addresses are never touched
  • A correction that looks like a rewrite is thrown out
  • Opens in a window so long texts can be read in full
And a lot more

Small tools, done properly.

Everything is optional. Switch pages off, reorder them, and keep only what earns its place.

Screenshots

Area, window, screen and scrolling capture, with arrows, text, pixelate and backdrops. Copy straight into your document.

Instant Text

Drag over anything on screen to read its text, or a QR code, on your Mac.

Calendar

A month at a glance, the day's agenda, and a Join button that shows up when a call is about to start.

Keep Awake

Timed sessions, automatic triggers while an app runs, and a safe closed-lid mode that cleans up after itself.

Photo Import

Plug in a camera card and it copies only the new photos, checks every file, ejects and opens your editor.

System at a glance

CPU, memory, disk, network and the busiest processes, with history and gentle alerts.

Privacy

Private by construction.

The language models run inside the app, on your Mac. There is no account to create, and nothing you write is sent anywhere.
