About sharemd.net
sharemd.net exists so that a piece of markdown can go from your clipboard to someone else’s screen, rendered, in the time it takes to paste. It is built on four principles: speed, no account, documents that expire, and no AI processing of what you write.
Why it exists
More and more of what people share at work is markdown: answers from AI assistants, files written by coding agents, notes, drafts, changelogs. It is written to be read, but the places it usually goes, such as chat tools and email, show it as raw symbols, and the tools that render it well ask for an account, a workspace and a decision about where the document should live.
Most of that text does not need a home. It needs to be read by a few people this week. sharemd.net is the tool for that case and does not try to be more. For a plain definition of the product, see what is sharemd.net.
Principles
Speed. Opening sharemd.net opens the editor. There is no landing page in front of it and nothing to configure. Paste, check the preview, select Share.
No account. Creating, editing, sharing, reading and exporting work without signup, and it is free. The reader does not need anything either; the link opens in a browser.
Expiry by default. Documents expire 15 days after creation, and their content is deleted automatically. Most shared text matters for days, and a system that forgets on its own holds less for less time. The longer argument is in why ephemeral documents.
No AI processing of your content. Nothing you paste is summarized, translated or rewritten by AI. The document is stored and shown as you wrote it.
What it does today
- A markdown editor with preview, split view, focus mode and light and dark themes.
- Rendering of tables, task lists, footnotes, highlighted code, Mermaid diagrams and KaTeX math.
- Share, which gives a read-only link and a write link. Links unfurl with a title, description and card in Slack, Discord, X, LinkedIn and similar tools.
- Shared documents are not indexed by search engines and are reachable only through their link.
- Export as
.mdor.html, and Copy Formatted for pasting rich text into other tools.
It does not have accounts, comments, version history or real-time collaboration. The FAQ covers the common questions about how it works.
