Sign

Send a PDF on WhatsApp, get it back signed. No apps, no accounts.

Start using SignFree · part of Ainoova Tools

Upload a PDF, say who signs and where, and send each person their own link on WhatsApp. They read it and sign with a finger on their phone; you get the signed PDF with a certificate of who signed, when and from where. Sign things yourself the same way. Claude can prepare, send and chase documents for you.

Signing links that open on any phone, no account needed
Send on WhatsApp in one tap, or copy the link
Signatures placed where you choose, in order of arrival
Certificate page: names, times, IP, device and file fingerprint
Sign your own PDFs from the share sheet

Ask Claude

“Send the Oreneta lease to Martí for signing and give me the WhatsApp link.”

“Who still hasn't signed the NDA?”

“Withdraw the old quote and send the new one to the same people.”
