Write, preview and share Markdown.

Free, no account, works in your browser. It started as an open-source project, and we've added a lot since.

What's Markdown?

Plain text with a few symbols for formatting: # for a heading, ** for bold, - for a list. It's how ChatGPT, Claude and Cursor write their answers, and AI tools read their instructions from Markdown files too (AGENTS.md, CLAUDE.md, Cursor rules). Easy for people and AI to read and write, but open a raw .md file and you just see the symbols. Viewer turns it into a proper page.

What we added

  • Share a whole report as one link.

    No account, and nothing saved on our side.

  • Your draft stays put.

    Opening someone's link opens a new tab instead of replacing your work.

  • Links open in the right view.

    Editor, split or preview, and straight to the right heading.

  • Safer shared links.

    We fixed holes in the original that let a link run code in your browser.

  • Works with your AI.

    Paste in what Claude or Cursor writes and it comes out formatted. Our own agents make share links straight from both.

How we tested this
