A scratchpad with superpowers.
Plain-text notes that do the thinking-adjacent chores for you — live math, currency & units, reactive variables, checklists and instant search. Private by design. Yours.
A free in-browser demo — no sign-up. The Windows app lands soon, with macOS, Linux, iOS & Android to follow.
It all happens in one plain note
No ten little boxes — just the real thing, quietly doing the math, the conversions and the bookkeeping while you type.
- 1Markdown, live. Headings, bold and lists style themselves as you type — the markers stay in view, so your notes are always plain text.
- 2Live math & units. Add a math region (the boxed part) and sums, percentages and unit conversions resolve as you type.
- 3Reactive variables. Name a value in that region and reuse it; change one number and every total follows.
- 4Currency, in place. Convert money with
toinside the region — rates are cached on your device. - 5Checklists, search & export. Track work with live progress, find anything across your notes, and take it anywhere.
Your notes never leave your machine
Notulee runs entirely on your device. Every smart feature — math, units, currency, search, readability — runs locally and deterministically, with no guesswork. No tracking. No account to create.
One note, many regions
Just start typing
A note is plain text. Headings, prose, lists — write however you think. Nothing to set up.
Add a region
Turn a block into a math, checklist, sum or code region from the toolbar. Each region gets its own superpower.
Watch it compute
Variables, sums, conversions and progress update live as you edit — every result is reproducible.
Find & export
Search across everything in an instant, then export a note or the whole stack when you’re done.
