About Markdown Studio

Markdown Studio is a markdown editor that runs entirely in your browser. You write on the left and see the formatted result on the right, updating as you type. It is built for people who already write in markdown — developers documenting their work, technical writers, anyone who keeps notes in plain text — and who want somewhere to draft, check and export a document without installing anything or signing up for another service.

Your documents stay on your device. There is no account to create and no server holding your text: everything you open or type is kept in your browser's own storage, and it is still there the next time you visit in the same browser. Nothing you write is uploaded, which also means that clearing your browser data clears your documents — so keep anything you need exported as a file.

Open a file, paste text, or fetch a raw markdown address, and work on several documents at once in tabs. Tables, task lists, code blocks with syntax highlighting, formulas and text-defined diagrams all render as you write. You can search and replace within a document, watch the line, word and character counts as they change, put two open documents side by side to see what differs, and export the result as markdown, as a single HTML file, or as a PDF. A dark and a light theme are both available, and the one you choose is remembered.

Markdown files usually end in .md, which is why people call them md files, and call a tool for opening one an md editor or an md viewer. Markdown Studio is the online kind: it runs in a browser tab rather than as an installed program, and its viewer is the formatted result of the text you write.
