Notulee
Features

Small note. Big powers.

Notulee keeps the calm of a plain-text scratchpad, then quietly does the math, the conversions and the bookkeeping for you. Here’s everything it can do.

Markdown

Plain text that styles itself

Notulee speaks Markdown. Headings, bold, italics, lists, quotes and links render live as you type — and the markers stay in view, so your notes are always plain, portable text.

  • Headings, bold, italics, lists, quotes & links
  • Markers stay visible — nothing is hidden from you
  • Live regions (math, checklist, code) sit right inside the Markdown
# Trip notes **Packing** — keep it light. - passport & charger - noise-cancelling buds > book the train early ## Budget
240 EUR to USD = 259.20 USD

Live math

A calculator that reads prose

Inside a math region, write numbers the way you’d say them — names, percentages and functions included. Results appear inline and recompute as you type. (Add a region with / → Math.)

  • Arithmetic, percentages and functions like ceil, round, powers
  • Phrases as names — after three letters they autocomplete
  • Always the same answer for the same input — deterministic, never a guess
# Pizza night
team : 7 pizzas : ceil(team / 2) slices : pizzas * 8 slices / team = 4.57 2 ^ 16 = 65,536

Currency & units

Convert without leaving the line

Money, distance, weight, temperature — in a math region, write to <unit> and Notulee converts in place. Exchange rates are fetched once and cached on your machine; you can pin custom rates too.

  • Currencies with locally-cached rates (works offline after first sync)
  • Physical units with dimension checking
  • Override any rate with your own
# Travel budget
4.50 USD to GBP = 3.56 GBP 2 km to mi = 1.24 mi 180 C to F = 356 F
Pin your own rate any time.

Reactive variables

Name it once, reuse it everywhere

In a math region, assign a value with name : value and reuse it across your maths. Edit the source and every dependent total updates instantly — like a spreadsheet, but in prose.

  • Multi-word names (food budget per person)
  • Chained dependencies recompute in order
  • Units and currencies carry through the maths
# Party ledger
food budget per person : 35 number of guests : 11 food budget per person * number of guests = 385
Bump the budget and the total follows.

Checklists & lists

Track work without a project tool

Start a checklist region and tick items off. Notulee keeps a live count, so you always know what’s left — no app-switching, no syntax to learn.

  • Live progress count (1/3 done)
  • Completed items strike through
  • Mixes freely with prose and math
# DB research Pick a store for the metrics panel.
- [ ] benchmark a wide aggregation - [x] verify the DuckDB extension loads - [ ] write up the findings 1 / 3 done

Search & replace

Find anything in an instant

Cross-note search stays fast even with thousands of notes. Find and replace within a note supports plain, word-anchored and regex modes.

  • Contains, whole-word, anchored and regex matching
  • Searches every note at once
  • No index to maintain — it just works
# Find in notes search : /budget.*Q3/ 3 matches across 2 notes Party ledger — budget per person… Travel budget — budget for Q3…

Native desktop

A real app, built for the keyboard

Notulee is a real native app — not a browser tab. Summon it from anywhere with a global hotkey, pin it on top while you work, and trust it to open instantly. Windows first, with macOS, Linux, iOS & Android to follow.

  • Global hotkey Ctrl+Alt+N to toggle the window
  • Pin-to-top and show/hide for quick capture
  • Light & dark themes, instant startup
# Quick capture Summoned with Ctrl+Alt+N — jot it and go.
- [x] pick the palette - [ ] wire the live demo - [ ] write the copy

The small things, handled

Sums & averages

Aggregate a column of numbers into totals, averages and counts automatically.

Readability score

A live reading-ease score keeps your prose clear.

Export

Plain text, Markdown, a URL scheme, or a zip of every note.

Ephemeral by default

Notes stack, pin and soft-delete — a scratchpad, not a filing cabinet.
