Where is the document stored?

In the link. The text is compressed into the URL itself, so there is no upload step and no database behind the page.

Can the person I send it to change it?

Not the link you sent. Edit a copy opens the document in the Markdown Converter, which produces a separate link and leaves yours alone.

How long can the document be?

Roughly six to eight thousand characters of prose once compressed. Past that the Markdown Converter says the link cannot be built rather than handing you a broken one.

Unguessable, but not secret. Anyone holding it can read the document, so treat it the way you would an unlisted link.

Will search engines index what I share?

No. Any URL carrying a document is served with a noindex tag and points its canonical at the empty tool page.

Opens your browser's print dialog, where you can also save the document as a PDF.

Edit a copy

This document is carried inside the link you followed. Nothing was uploaded, and editing a copy leaves the original link exactly as it was sent.

As soon as there is something here, the address bar holds the whole document. Copy that URL and whoever opens it sees the rendered page, with no editor and nothing to sign into.

How to use the Document Viewer

Paste Markdown, or open a link someone shared with you.
The page renders it as a formatted document with no editor around it.
Copy the URL out of the address bar to send the document on.
Print it, or save it as a PDF, straight from the page.
