Aboard Sign drops zero-login document signing

DocuSign and legacy e-signature suites have turned basic agreement execution into bloated, expensive legal theater. By pairing client-side cryptographic hashing with an open API and `llms.txt` spec, Aboard Sign turns document signing into a lightweight, zero-retention primitive that autonomous AI agents and developers can trigger directly.

• –**Client-side signing and zero storage**: Documents are hashed and signed locally in the user's browser, eliminating the security and privacy risks of storing confidential contracts on third-party servers.
• –**First-class agent support**: With dedicated `llms.txt` documentation and a straightforward REST endpoint, AI agents can generate agreements and dispatch them for execution programmatically.
• –**Self-verifying cryptography**: Each finalized PDF contains embedded cryptographic fingerprints verifiable offline or via standard tooling, removing reliance on vendor lock-in.
• –**Disrupting legal SaaS bloat**: Created by Paul Ford and attorney Rich Ziade, the tool demonstrates how modern web primitives can replace multi-thousand-dollar enterprise software subscriptions.
