Built-in acknowledgments for policies, handbooks, and internal attestations are available today. Legally binding e-signatures for contracts, offer letters, and NDAs are on the roadmap.

Everything you need for document signing
Built into your document workflow, not bolted on
Embedded Signing
Signers complete signatures without leaving your platform. Automatic per-organization branding.
Real-Time Status Tracking
See who has signed, who has not, and when. Live updates via webhooks keep your dashboard current.
Automatic Reminders
Configurable reminder frequency for pending signers. No manual follow-up needed.
Immutable Audit Trail
Every action logged with timestamp, actor, and IP address. Compliance-ready for any audit.
Zero Configuration
E-signatures work out of the box. No API keys, no separate accounts. Just verify your email and start sending.
Parallel or Sequential
All signers at once, or in a specific order. You control the signing workflow.
Smart Mode Selection
Muin auto-recommends the right mode based on document type. Contracts will get legally binding e-signatures (coming soon); policies get acknowledgments today.
Signer Roles & Workflows
Signers, approvers, CC recipients, and in-person signing. Route documents through the right people.
Admin Analytics
Track completion rates, average signing time, and usage breakdown. Full visibility into your signing operations.
Signature Templates
Save and reuse signature packages for common document types like offer letters and NDAs.
Bulk Send
Send the same document to many people at once — volunteer agreements before a distribution event, annual board-member conflict-of-interest forms, or staff policy acknowledgments. One upload, every signer gets their own envelope.
