Keep what mattersin view

Underline is a wide touch display that sits under your monitor. It keeps the few things that matter right now in one place: the agents waiting for you, your tasks, your day, your music.

Coming to Kickstarter. Early Bird is €249 for the first 300 backers.

Everything wants your attention.
A few things need it.

Your screen is full: the editor, the browser, the chat, ten terminal tabs. Somewhere in there is the one thing that is actually waiting for you. An agent that stopped to ask a question. A task you meant to hand off. A call in ten minutes.

You find it forty minutes late.

A desk with a monitor and a laptop, both covered in terminal windows.

One place for the few things that matter

The agents waiting for you, your tasks, your day, your music. The rest of your screen stays on the work.

Only what needs you

Whatever is waiting for you moves to the top and stays there until you deal with it.

Your day, next to your tasks

Today's calendar, with a countdown to the next meeting.

Every agent, every project

Your AI coding agents and your own tasks, grouped by project. Each one says where it stands: running, waiting for you, or done.

A backlog for mid-task ideas

Write an idea down without leaving what you are doing, then hand it to an agent when you are ready.

Your music, under your code

Playback, queue and search for Spotify, on a screen you can reach without switching windows.

A calm screen when nothing needs you

Animated scenes with a clock, for the hours when everything is simply running.

2 need you3 running

It asks. You tap. It keeps going.

You glance down, you see what needs you, you answer with one tap, and you look back up. Say OK, ask to be reminded later, or jump straight into the agent's terminal.

This request is live. Answer it.

The Underline prototype on a desk under a monitor, showing a pixel-art night street with a clock.

The prototype is real

This is the working prototype on our desk. The production Underline will look the same.

Open source. Yours to change.

When the campaign is funded, we publish all of the software on GitHub under the MIT license, within a month of the campaign ending. Underline runs on your own computer and keeps your data there: no account, no cloud service.

  • Fork it. Change anything you like.
  • Write your own screens. It comes with a kit for screens and widgets, and an agent can write one for you.
  • Share them. Good screens travel.

Questions

Is it just a second monitor?

It shows up to your computer as a display, so you can use it as one. What makes it Underline is the software that runs on it.

Which agents does it work with?

Claude Code, Codex, Cursor and others. Any agent that can run a command can report to Underline.

Does my code leave my machine?

No. Agents report a short status line to the app on your own computer. Nothing is sent to us.

Do I need an account?

No. The software runs on your computer.

Will it work with Windows or Linux?

Yes. Underline comes with apps for macOS, Windows and Linux.

Can I write my own screens?

Yes. The software is open source, and it comes with a kit for writing your own screens and widgets.

Is a power adapter included?

No. Underline is powered over USB-C from your computer or any USB-C charger.

When does it launch, and what will it cost?

Underline is coming to Kickstarter. Early Bird is €249 for the first 300 backers, and €299 after that.

What if the campaign does not reach its goal?

Nobody is charged.
