# AddSign > AddSign is free electronic signature software with AI-powered document analysis. Send, sign, and manage documents online in under 2 minutes. The DocuSign alternative built for small businesses, real estate agents, and freelancers — generous free tier, no per-envelope fees, and a 60% lower paid price than DocuSign. ## What AddSign does - Send documents (PDF or Word) for electronic signature from any device - Recipients sign online without creating an AddSign account or downloading software - Drag-and-drop signature, initial, date and text fields onto a document - AI document overview: summarizes PDFs, extracts key dates and terms (5/week on Free, unlimited on Pro) - Bulk send and template support for repeated agreements (real estate listings, leases, NDAs, SOWs) - Audit trail with timestamps, IP addresses, and email verification on every completed document - SHA-256 document hash and signature certificate stored for ESIGN Act and UETA compliance - Branded sender experience: custom logo and color (Pro); replies to signing requests go to the sender's email ## Who uses AddSign - Real estate agents — purchase agreements, listing contracts, lease agreements, disclosures - Property managers — lease renewals, addenda, move-in/out forms - Freelancers and consultants — client contracts, statements of work, invoices - Small businesses replacing DocuSign, HelloSign, or PandaDoc - Contractors, law firms, photographers, accounting firms, marketing agencies, insurance brokers ## AI agents & MCP (agent-ready e-signature) AddSign works with AI agents through the open Model Context Protocol (MCP). An assistant like Claude can list the user's templates, send documents for signature, check signing status, remind pending signers, and fetch the signed PDF with its SHA-256 hash — the agent sends, humans sign. - Listed in Anthropic's Claude Connectors Directory (since 2026-10-01): https://claude.ai/directory/connectors/addsign — connect from Claude's connector directory with an AddSign login (OAuth, no API key) - Hosted MCP connector URL (for any MCP client, or as a custom connector): https://addsign.io/api/mcp - Claude Desktop extension (one-click install, API key in OS keychain): https://addsign.io/downloads/addsign.mcpb - npm package for any MCP client: addsign-mcp (official MCP Registry: io.github.rmindgh/addsign-mcp), authenticated by an ADDSIGN_API_KEY - Safety design: the agent cannot cancel, void, or delete anything; Claude confirms each send and reminder with the user by default; the account owner receives an email for every agent-initiated send; access is revocable instantly.
