No login. No friction. Just links.

Drop it. It renders.

Markdown, AI write-ups, HTML pages, PDFs, spreadsheets, Word docs, video and zipped sites become links that open rendered in any browser.

Start writingUpload a file

Markdown never needs an account. Files need a free one.

How it works

Two ways in. One link out.

Write a document or upload a file. Either way you get a link that opens as a page in any browser.

Files that render

Upload a file. Share a link that opens it.

HTML pages, PDFs, spreadsheets, Word docs, images, video and zipped sites open rendered in any browser, with nothing to download.

Make the link yours.

Name it, lock it, set it to expire or encrypt it. The link changes as you go, and so does what people see when you paste it in a chat.

End-to-end encryption

The key lives in the link

Encrypt a document and the key goes after the # in its link. Browsers never send that part to a server, so Markdrop stores ciphertext it has no key for.

Updates as you type
The first line becomes the title. It is sealed too.
AES-256-GCM, in your browserOnly ciphertext is uploaded. The key never leaves the link.

README builder

Build a README in blocks.

Pick the sections your project needs, put them in order, and watch the README render as you go. Diagrams and math come out drawn, not as code.

Every document also prints to a clean PDF.

Blocks

Click to add, again to remove

Each block is a section template in the real builder. Diagrams and math are written as text, then drawn on the page.
