Formatted as you type
No preview pane. Write Markdown and see the finished document in the same place.
Markdown editor for Windows · Mac coming soon
Markdown, formatted as you type.
Headings, bold, lists and tables appear right away, just as they will in the finished document. The syntax shows only where your cursor is: always within reach, never in the way.
Free 15-day trial · One-time purchase · No account
Everything you need to write. Nothing in the way.
Source in one keystroke
Press Ctrl / to see the raw Markdown. Your cursor and selection stay on the same words.
Saves only what you changed
The rest of the file stays identical, byte for byte. No reformatted tables, no noisy Git diffs.
Math and diagrams
LaTeX formulas, Mermaid, Graphviz, flowcharts, mind maps and charts, drawn live in the text.
Built for real projects
Tabs, split view, folder tree, outline and search across every file in the folder.
Made for focus
Focus and typewriter modes, light and dark themes, and your own CSS themes.
Switch to source. Your cursor stays put.
When you want full control, Ctrl / flips to the source. The selection stays on exactly the same text, in both directions. Switch back and keep writing.
Two documents, side by side.
Open your notes next to your draft, jump between files from the folder tree and find anything with search in files.
Formulas, diagrams and code, right in the text.
Write a Mermaid diagram or a LaTeX formula and watch it render as you type. Code blocks get syntax highlighting for dozens of languages.
Dark theme. Focus mode.
Dim everything except the paragraph you're writing, or let typewriter mode keep your line in the middle of the screen.
