One calm space instead of a dozen tabs
Scattered notes, broken concentration and endless app-switching quietly drain your day. Cooper brings the essentials of deep work together so momentum is the default.
Everything in one place
Notes, focus timer and writing help live side by side — no context-switching, no lost trains of thought.
Built for deep focus
A distraction-free canvas and a gentle work/break rhythm help you stay in flow for longer.
Truly private
Your notes are end-to-end encrypted, so what you write stays yours — even we can't read it.
Works everywhere
Runs right in your browser on desktop, tablet and phone, and installs like a native app when you want it.
A focused toolkit, thoughtfully designed
Every feature earns its place. Here's what you get from day one — no setup, no clutter.
Distraction-free notes
A clean live-Markdown editor with headings, lists, tasks, tables, images and a quick “/” command menu. It autosaves as you type.
Focus timer
Work and break cycles with gentle alerts keep your rhythm going, so you stay productive without watching the clock.
End-to-end encryption
Your notes are encrypted on your device before they're ever saved. Only you hold the key.
Focus music
Thousands of built-in radio stations to set the mood and keep the outside world at bay while you work.
Progress tracking
Every focus session is logged, so you can look back and see just how much deep work you're getting done.
Install as an app
Add Cooper to your desktop or home screen and launch straight into your workspace, online or off.
The real product, not a mockup
Every clip below is captured straight from Cooper — here's what your day actually looks like.
Write in Markdown, live
Type the way you think. Headings, lists, tasks and quotes format themselves as you go — and every keystroke autosaves, end-to-end encrypted.
Focus in sprints
Start a session and settle into deep work. Cooper keeps the rhythm of work and breaks, so you stay productive without watching the clock.

Everything in one place
Your notes stay tidy and a click away, so you can always pick up exactly where you left off.
A second pair of eyes on your writing
Select any text and let Cooper refine it — clearer, sharper and easier to read, with your Markdown and meaning preserved.
- Sharpen clarity — turn rough notes into clear, readable prose in a click.
- Fix grammar & flow — smooth out awkward phrasing without changing your voice.
- Polish the tone — keep it professional, warm or concise — however you need it.
This is just the start. We're building AI that helps you think and work faster across your whole workspace — always assisting, never getting in the way.
A simple loop that keeps you moving
No manuals, no onboarding maze. Three steps are all it takes to make deep work a habit.

Capture your thoughts
Open a note and start writing in plain Markdown. Ideas, tasks and plans — all in one tidy place.
- 2
Focus in sprints
Start the timer, pick your soundtrack and work in focused cycles with breaks that keep you fresh.
- 3
See your progress
Review your sessions and finished notes, and watch your focused hours add up over time.
