Your personal command center .
Think, plan and do, in one browser tab. Notes, a calculating workbook, task boards and 20 everyday tools composed page by page, however you need them.
Nothing to install. Nothing to sign up for.
The workspace
Every page is its own canvas
Most tools decide the layout for you. This one hands you a blank page and every block you might want, then gets out of the way. It does the same for the next page, and the one after that.
- Drag, drop, resize
- Put every block exactly where you want it. The canvas remembers the layout for each page.
- Pages and folders
- Create as many pages as you need, and organise them into folders once there are enough to want one.
- Page links
- Select a word and link it to another page, then click through whenever you need it. Pages stop being separate documents and become one connected workspace.
- Templates
- Save a layout you like and start the next page from it instead of rebuilding it.
- Command palette
- Press ⌘K to search for a block and drop it on the page. Press ⌘F to search your whole workspace and jump straight to any page.
Notes
A writing surface that knows what a task is
Built on TipTap, so it behaves like the editor you already expect. The difference is what happens to the checkboxes you write.
- Slash menu: press / to insert a heading, list, table or equation
- Checkboxes that carry a scheduled date, an importance level and a mini calendar picker
- Code blocks, tables and fold-away sections
- Images, YouTube embeds and file attachments
- Equations, block or inline
- A live Workbook block, right inside the note
- Export to PDF
- Autosaves as you type. There is no save button
One source of truth. Give a checkbox a scheduled date and it turns up on your Kanban board, your Task Calendar and your Focus Board. Change it in any of them and you have changed the note, because there is only ever one underlying document.
Workbook
A notepad that does the maths as you type
Write your thinking on the left. Answers appear on the right, line by line. Change an assumption near the top and everything below it updates.
Name a line and reuse it further down as a variable. Pull a running
total with sum.
Units, functions, names and dates suggest themselves as you type,
and Tab or Enter accepts them.
Type it how you would say it
Around thirty functions, with autocomplete
- Basic
- sqrt · abs · round · floor · ceil · factorial
- Trigonometry
- sin · cos · tan · asin · acos · atan · atan2
- Hyperbolic
- sinh · cosh · tanh · asinh · acosh · atanh
- Logarithms
- ln · log · log2 · log10
- log is base 10, ln is natural
- Aggregates
- sum · avg · min · max · clamp
- Angles & constants
- degrees · radians · pi · e
Dates work too: today() and date() support date
literals and date math, like date(A) - date(B) to weeks.
Units and currency, built in
Length, mass, temperature, area, volume, speed, energy, power,
pressure, time and torque, plus live currency rates. Aggregates work
across mixed units too, so min(100 cm, 2 m) does the right thing.
Boards & tasks
Three ways into the same tasks
Every board reads from the checkboxes inside your notes. Nothing to sync, nothing to keep in step, because there is only one list.
Move work along
Kanban Board
Drag task cards between columns, and add or remove columns of your own so the board matches how you actually work. Moving a card updates the task in your note, because it is the same task.
See it against the month
Task Calendar
Everything with a scheduled date, laid out on a month or week grid, so a week that is quietly overloaded looks overloaded. Follow-finger dragging on mobile.
Where things actually stand
Focus Board
Every task split four ways: today, overdue, unscheduled, and today's done. Tick one off, reschedule it, or jump to the note it lives in without leaving the board. Scope it to a single page, any folder above that page, or everything at once.
Task Activity
A contribution-graph strip of what you have actually been finishing, the honest counterweight to a to-do list that only ever grows.
The catalog
20 blocks, one workspace
All the small tools you keep a browser tab open for, living in the same place as the work they belong to.
The pair you live in
A writing surface and a thinking surface, side by side.
Tasks & boards
Four blocks, one underlying task list.
Kanban Board
Your note tasks as cards you can drag between columns.
Task Calendar
Everything with a scheduled date, laid out on a month or week grid.
Focus Board
Every task in four quadrants: today, overdue, unscheduled and today's done.
Task Activity
A contribution-graph strip of everything you have finished.
Time & timers
Everything clock-shaped, in one place.
Digital Clock
A clean digital clock that scales to whatever space you give it.
World Time
Track several cities at once, with a focus mode that blows one up big.

Set it, forget it, get a nudge when it is done.
Open the free tool →Chronometer
A stopwatch that logs lap times as you go, for when you need to time something exactly.

Open the free tool →Alarm
An alarm for a specific time of day, in the tab you already have open.

The small tools you keep a browser tab open for. Now they live with your work.

Canvas
When the answer is a drawing.
Online whiteboard
A full Excalidraw whiteboard, on the same page as everything else. Sketch a flow, a floor plan or a rough wireframe, in the hand-drawn style that makes it obvious an idea is still a draft.

It all runs on your machine
This is the part that actually matters. KontrolRoom is not a thin client for someone else's server. It is a workspace that happens to run in a browser tab.
Works offline
Everything is stored in your browser with IndexedDB. Close the laptop on a plane and keep working.
No account needed
There is no sign-up wall and no email required. Open the page and start working.
Your data stays yours
Nothing is uploaded. No analytics on your content, no training on your notes, nothing to leak.
Free to use
The whole workspace, every block, at no cost. Cloud sync is the only thing that will ever be optional and paid.
One honest caveat. Browser storage is not infinite, and no browser promises to keep it forever, Safari especially. KontrolRoom quietly asks for persistent storage and gives you one-click backup and restore, but if this is real work, read how your data actually stays safe .
Coming next
Want it on your other devices?
Cloud sync is being built, and it will stay strictly optional. The offline workspace keeps working exactly as it does now whether you turn it on or not. Leave your email and we'll tell you when it lands.
One email when sync ships. Nothing else, and no sharing your address with anyone.
Open a tab. Start working.
No install, no account, no trial. The whole workspace is there the moment the page loads.
