Get a contract signed with no account or app: email it to everyone who signs, CC sign@aboard.com, and each person gets a link to read and sign it in the browser. Everyone is mailed the signed PDF, every page cryptographically signed. The document isn't kept.

Hunting this for Paul Ford (@ftrain) and the team at Aboard, where I'm CTO.
The whole product is an email address. Send the agreement to the people who need to sign it, CC sign@aboard.com, and everyone gets a link of their own to read it and sign in the browser. No accounts, no login, no app to install. When the last person signs, everyone is mailed the signed PDF: every page carries its own fingerprint, the file is sealed with a standard PDF signature, and the document is deleted on our side. All that's kept is a fingerprint on a public log, so anyone can check later that a copy is the real one.
Takes Word, PDF, RTF or Markdown, up to 5 signers. It's built for assistants too: there's an llms.txt and an API, so Claude or ChatGPT can draft the agreement in Markdown, start the signing with one POST, tell you where it stands, and later check that a signed PDF is the real thing. No SDK, no account.

Let us know what you think! We'll be watching the comments.
love that you dont keep the doc. but if someone loses the signed pdf a year later theres no way to get it again right? maybe worth a big "save this" line in the final email
the whole product being one email address is a nice touch, nobody has to make an acount just to sign a 2 page NDA
since every signer gets their link by email, what happens when it lands in spam on their side??? can the sender see who never opened it, so they know to nudge that person some other way???
what happens if one of the signers replies all asking for changes instead of signing, does everyone start over
