Legally Binding & Compliant

Every signature is fully enforceable under the ESIGN Act and eIDAS regulation. Each signed document includes a tamper-proof audit trail with timestamps, IP addresses, and signer authentication details for complete legal validity.

Real-Time Status Tracking

Know exactly where every document stands. Track when recipients view, open, and sign your documents in real time. Get instant notifications at every step so you never have to follow up blindly.

Multi-Party Signing Workflows

Coordinate complex signing processes with multiple parties. Define custom signing orders, set sequential or parallel workflows, and ensure every stakeholder signs in the right sequence — all managed from a single dashboard.

Sign Any Document Format

Upload PDF, DOCX, PPTX, XLSX, HWP, and more. AiDocX automatically converts your files to PDF for a consistent, professional signing experience. No manual conversion needed — just upload and send.

Complete Audit Trails You Can Trust

Every document signed through AiDocX automatically generates a downloadable Audit Trail PDF certificate that stands up in court. Each event is recorded with precise timestamps, IP addresses, device information, and authentication methods. The certificate details the entire signing history — who signed, when, and from where — giving you an airtight record for compliance, disputes, or internal governance. NDA signatures also generate the same tamper-proof audit trail, so you always have legal proof of acceptance. Unlike basic e-signature tools, AiDocX audit trails are embedded directly into the signed PDF for permanent, portable proof.

Mobile-First Signing Experience

Your signers can review and sign documents from any device — smartphone, tablet, or desktop — without installing an app or creating an account. The signing interface adapts seamlessly to any screen size, with touch-optimized signature capture and a distraction-free layout. This frictionless experience means faster turnaround times: documents that used to take days to sign now get completed in minutes, wherever your signers happen to be.

Custom Branding That Builds Trust

Make every signing interaction an extension of your brand. With AiDocX Pro and above, customize your signing pages with your company logo, brand colors, and personalized messaging. Branded signing pages increase signer confidence and completion rates by presenting a cohesive, professional experience from the email invitation through the final signature. Your recipients see your brand — not ours.

AI-Powered Document Intelligence

AiDocX goes beyond signatures. Before you send a document for signing, our AI engine analyzes the content to surface key clauses, flag potential risks, and summarize critical terms. After signing, track how recipients engage with your document through built-in analytics — see which pages they spend the most time on, when they view the document, and how long the review takes. This intelligence helps you refine your documents and close deals faster.
