Notes that take code seriously

DigiPages is a writing app for software engineers. Real syntax highlighting in 21 languages, LaTeX that renders as you type, and backlinks that make a folder of notes behave like a wiki.

Rate limiter — design notes

Token bucket, refilled lazily on read. Nothing schedules a timer, so an idle key costs nothing.

TypeScriptCopy

export function take(key: string) {
  const bucket = refill(key, now());
  if (bucket.tokens < 1) return false;

  // Decrement before the caller can await anything.
  bucket.tokens -= 1;
  return true;
}

💡

Burst capacity is the bucket size, not the refill rate — see Load test results.

Built for the way engineers write

Design docs, incident write-ups, scratch notes that turn into RFCs. The blocks you reach for are the ones that were missing.

Code blocks, done properly

Syntax highlighting across 21 languages, a language picker on every block, and a copy button. Paste from your editor and the formatting survives.

LaTeX that renders as you type

Display and inline equations, KaTeX-backed, with a live preview while you edit. Type $$ at the start of a line and start writing maths.

Backlinks, not just links

Link one page from another and the reference shows up on both. A folder of notes starts behaving like a wiki without you maintaining an index.

Structure that holds

Folders, sub-pages and drag-to-reorder, with ordering that survives two people — or two tabs — moving things at once.

Layout when you need it

Two- and three-column sections, tables, toggle lists, callouts and an auto-generated table of contents. All from the / menu.

Search that spans everything

One search across every page you own, titles and body alike, without leaving the keyboard.

Coming soon

AI transforms, as an add-on

Rewrite a block, tighten a paragraph, turn a wall of notes into a summary — on the block you have selected, not on your whole document. It will be an optional extra on top of your plan, not something bundled into the price whether you want it or not.
