Indigo eSign is an “Indigo Software” product that combines AI-powered contract analysis with legally binding electronic signatures in one web-based platform. Designed for individuals, businesses, and legal teams, it helps users review agreements, identify potential issues, and complete signing without switching between separate tools. Its AI analyzes uploaded PDF and DOCX contracts, extracts clauses, provides plain-English summaries, assigns risk indicators, and flags concerns such as uncapped liability, auto-renewal terms, or missing clauses. Users can review recommendations before sending documents for signature.

The service supports agreements including master service agreements, nondisclosure agreements, vendor contracts, purchase orders, leases, employment agreements, and statements of work. Its signing process is presented as compliant with the US ESIGN Act and UETA and the EU eIDAS framework, with mobile signing, encryption, and audit logs. Indigo eSign also offers tiered plans, from a free option to Basic, Pro, and custom Enterprise plans. For developers, a REST API can automate contract review, signing workflows, and agreement status tracking, with documentation and a sandbox environment available.
