Open a file in Ballpoint

Add a file. You get a link that opens it beside a Ballpoint Box, where what you write is signed as written by a person.

Choose a file or drop one here PDF · Word (.docx) · notebook (.ipynb) · Python (.py) · .txt · .md · .tex

Files stay in this browser: they are not uploaded, so a link opens only in this browser for now. Signing sends Ballpoint a fingerprint of what you wrote, never the file.
