One click.
One link.

ShareNotes against the usual markdown editors.
Answers, briefly.
How do I share a markdown document online?
Open ShareNotes, paste or type your markdown, click Share. You get a memorable URL like sharenotes.dev/blue-fox-42. Anyone with the link can view the rendered markdown — and edit it if you didn't lock editing.
What's the difference between ShareNotes and Dillinger?
Dillinger is a single-user markdown editor — you write and export, but there's no shareable URL. ShareNotes gives you a memorable URL the moment you click Share, plus real-time sync between every viewer. The trade-off: Dillinger has more export targets (Google Drive, Dropbox); ShareNotes optimizes for sharing.
Do code blocks get syntax highlighting?
Yes. Code inside fenced markdown blocks (```ts, ```python, etc.) is auto-detected and highlighted across 35+ languages via highlight.js. Inline `code` gets monospaced background styling.
Can I edit collaboratively?
Yes. Every device viewing the same URL stays synced over WebSocket. Two people can edit a markdown note simultaneously and both see the result. There's no separate sign-in or invite — anyone with the link is in.
Is there a markdown notepad without a login requirement?
ShareNotes is exactly that — no account, no email, no sign-up. Write markdown, share the link, done. Optional password protection if you want to gate edits or views.
What markdown flavor is supported?
GitHub-Flavored Markdown via the marked parser. Headings, bold/italic, lists (ordered and unordered), task lists, code blocks with fences, blockquotes, tables, links, images and horizontal rules all render.
