AddSign

AddSign lets Claude handle the paperwork side of e-signatures for you. Connect your AddSign account and ask in plain language:

• "Send the lease template to Maria Lopez, maria@example.com, for signature."
• "Did the buyers sign the listing agreement yet?"
• "Remind everyone who hasn't signed the NDA."
• "Get me the signed PDF for the Ocean Ave purchase agreement."

What Claude can do

• List your templates and documents
• Send a document from one of your templates to the signers you name
• Check status: who viewed, signed, or declined, with the reason and the audit trail
• Remind pending signers (each signer at most once every 4 hours)
• Get a short-lived download link for the signed PDF, with its SHA-256 hash for verification

Built-in safeguards

• Claude asks you to confirm before every send or reminder, and must use the exact email addresses you give it
• A preview mode shows exactly what would be sent before anything goes out
• You get an email for every document Claude sends, with a link to cancel it
• Claude cannot cancel or delete documents, change templates, touch billing, or see your API keys
• Every action is recorded in the document's audit trail; disconnect any time

Signers don't need an account or Claude. They sign on any phone or computer. Templates are created in the AddSign dashboard. An AddSign account is required; the free plan includes the connector.
