What it does

Quick to open. Ready for real work.

Write

A calm place to type

  • Tabs for quick scratch notes alongside your document, remembered between sessions
  • Syntax colours for 17 languages, seven colour schemes and a theme editor of your own
  • Line numbers, word wrap, bracket matching, auto-closing brackets and smart indentation on Return
  • Focus mode and typewriter scrolling for writing without distraction, with an optional daily word goal
  • Automatic crash recovery, so a power cut never costs you a draft
Edit fast

Power tools, when you want them

  • Multiple cursors: ⌥-click, column select, Select Next Occurrence (⌘D) and Select All Occurrences
  • Move, duplicate, delete and sort lines from the keyboard
  • A Transform menu: change case, trim whitespace, pretty-print or minify JSON, encode or decode URLs
  • Fold code blocks, comment and uncomment lines or blocks, and find and replace with regular expressions
  • Split the window side by side or stacked, each side showing its own tab
Notes & folders

Open a whole folder

  • A sidebar to browse a folder’s files, and Find in Folder to search every file in it
  • Link notes with [[wikilinks]]: ⌘-click to follow one, and type [[ to pick a file by name
  • Grant a folder once and Simplitext remembers, so links keep working without asking again
  • A command palette (⇧⌘P) to run any command, switch theme or language, or open a recent file
Markdown & more

Preview, export, polish

  • Live Markdown preview with typeset maths (LaTeX), Mermaid diagrams and coloured code blocks, scrolling in step with your text
  • Export the rendered page as HTML or a paginated PDF
  • Open and save in UTF-8, UTF-16, Latin-1 and more, with Windows (CRLF), Unix and classic Mac line endings kept exactly as they were
  • An AI Writing Assistant on Macs with Apple Intelligence: fix grammar, rewrite, summarise or ask your own question, watch the answer arrive, see exactly what changed before you accept it, and use code actions such as explain code or write a docstring

How it works

Open it. Start typing.

  1. It starts on a blank page. No setup, no account and no start-up dialogs. Open a file with ⌘O, or drop one on the window.
  2. Everything else is one keystroke away. Press ⇧⌘P and type what you want to do. The Keyboard Shortcuts sheet (⇧⌘/) lists the rest.
  3. Your files stay yours. Documents are plain files saved where you choose, in the encoding and line endings you picked.
