What Your Digital Signature App Can Do
Document Upload and Preparation
Let users upload PDFs, contracts, or forms and place signature fields exactly where they're needed. Chattee generates clean drag-and-drop interfaces for document preparation that feel intuitive from the first use.
Secure Electronic Signatures
Capture legally binding e-signatures with timestamped audit trails. Your app can support drawn signatures, typed names, or uploaded signature images, all stored securely and linked to the signed document.
Multi-Signer Workflows
Set up sequential or parallel signing flows where multiple parties receive notifications and sign in order. Think contract approvals, onboarding packets, or vendor agreements with several stakeholders.
Real-Time Status Tracking
Give senders and signers full visibility into where each document stands. Pending, viewed, signed, completed. Automatic reminders keep things moving without manual follow-up.

Key Considerations When Building a Digital Signature App
Legal Validity and Compliance
Electronic signatures carry legal weight in most jurisdictions under frameworks like eIDAS and ESIGN. Design your app with proper audit trails, timestamps, and signer identification to ensure enforceability.
Signer Identity Verification
Consider how signers prove who they are. Email verification, SMS codes, or knowledge-based authentication add layers of trust depending on your document sensitivity and regulatory needs.
Document Security and Encryption
Signed documents need tamper-proof storage. Implement encryption at rest and in transit, hash-based integrity checks, and access controls so only authorized parties can view completed agreements.
Notification and Reminder Systems
Unsigned documents stall deals. Build automated email or SMS reminders that nudge signers at the right intervals without being intrusive. Completion rates improve dramatically with well-timed follow-ups.
Mobile-Friendly Signing Experience
Many signers will open your documents on a phone. A responsive signing interface with touch-friendly signature capture is essential for high completion rates across devices.
Audit Trail and Record Keeping
Every action on a document should be logged. Who opened it, when they signed, their IP address, device info. This creates the evidence trail that gives digital signatures their legal standing.
