E-signatures, AI document generation, open verification, public transparency log, secure document locker, and 12 PDF tools — in one platform, starting at $0/mo.
SignForge is an AI-native e-signature platform. Amanda AI can generate documents from a prompt, place signature fields, and send them for signing — all via conversation. Every signed PDF carries open-standards verification proof (W3C Verifiable Credential) embedded in the document itself. SignForge also includes a developer API, MCP server for AI agents, and 12 free PDF tools. DocuSign is a mature enterprise platform with deep integrations, AATL-trusted PKI, and a large ecosystem.
Yes. Amanda AI can generate 12+ legal document types — NDAs, service agreements, employment contracts, consulting agreements, and more — from a simple description. She also places signature fields automatically. DocuSign offers document generation capabilities as well, but SignForge's describe-and-generate workflow is built into the core product from the free tier.
SignForge uses open standards: a W3C Verifiable Credential, embedded public keys, and a public Merkle transparency log. The proof is portable — it lives in the signed PDF and can be verified offline, in any tool, without contacting SignForge. DocuSign uses PKI with certificates from their own Root CA, trusted through Adobe's AATL program. Their signatures auto-validate with a green checkmark in Adobe Reader. These are different trust models with different strengths.
Yes. SignForge includes a REST API, webhooks, an embeddable signing widget, and a published MCP server (14 tools) for AI agents like Claude and Cursor. The API is available on the free plan with 5 API envelopes per month. DocuSign also has a mature API ecosystem, starting from $50/mo for developer access.
SignForge is a better fit if you want AI-powered document generation, open-standards verification that isn't locked to one PDF viewer, developer tools included free, or you're a smaller team that doesn't need DocuSign's enterprise integrations. It's also a better fit if you value portable, publicly auditable proof over traditional certificate-based trust.
DocuSign is likely a better fit if you need AATL-trusted signatures that auto-validate with a green checkmark in Adobe Reader, deep integrations with enterprise systems like Salesforce and SAP, Qualified Electronic Signatures (QES) for advanced eIDAS compliance, or the mature ecosystem that comes with the market leader. SignForge takes a different approach — open standards and AI-native workflows rather than enterprise PKI infrastructure.
Amanda AI drafts your documents. Open-standards verification makes them portable. Developer API and 12 PDF tools included. Starting at $0/mo.
