What is eSign PDF?

eSign PDF by Portant lets an AI assistant send a document for electronic signature and return the signed copy. Give the assistant a link to a PDF, a Google Doc shared by link, or ask it to write the document, such as an NDA or a short agreement. Portant emails the signer a private link. The signer reads and signs in a browser, with no account. Portant then emails you the signed PDF with a signing certificate page. The assistant can also check the status, find a request by the signer’s email, give you a link to the signed file, or cancel a request that is not signed yet.

The assistant never signs for anyone: every signature comes from a person in a browser. Documents are encrypted before they are stored. Emails and signing pages are available in English, Spanish, German, French, Japanese, Italian, Dutch and Brazilian Portuguese.

How it works

1. You ask your assistant to get a document signed, and you give it the signer's name and email.
2. Portant emails the signer a private link. The signer reads and signs in a browser, with no account.
3. Portant emails you the signed PDF with a signing certificate page. The assistant can also give you a link to it.

The assistant never signs for anyone: every signature comes from a person in a browser. When you must sign too, you sign first, then the other person.
