The E-Sign API your AI agents were missing.

Send any document. Atlas detects fields, pre-fills data, and returns a signable link in one API call. No templates, no manual setup. Atlas gets smarter with every doc. The next deal with the same company prefills itself.

Atlas vs DocuSign

You've already configured DocuSign. Why switch?

Setup time isn't the point. DocuSign resets with every new document type. Every deal starts from scratch. Atlas handles any document on the first call and gets smarter with every contract you send.

Atlas Context

Gets smarter with every deal.

Every contract you send builds a profile of who you work with. Name, signatory, jurisdiction, standard terms. The more you use it, the less you have to specify. It just compounds. Other e-sign tools can't offer that.

  • Every envelope adds to a counterparty profile. Who signs, their jurisdiction, how long they take.
  • The second deal with the same company: Atlas already knows who signs for them.
  • Connect Google Drive, Dropbox, Box, or OneDrive to seed it with your existing archive.
