readm3

Paste

Paste anything.
Get a private link.

Text of any kind, a PDF or an image, behind a secret link. No account. Markdown renders as a document, code is highlighted and folds, and the link expires when you say. Only a hash of the secret is kept, so nobody can list or find it.

The language is detected from the name or the content. Up to 256 KB.

Ctrl / ⌘ Enter

The page above is a form over one endpoint. Everything it does, these do too.
