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.

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 BoldSign or built-in based on document type. Contracts get legal signatures. Policies get acknowledgments.

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.
