Lupa AI vs Zignt

AI-Powered Upscaling

Lupa AI employs advanced artificial intelligence technology to perform near-lossless upscaling. This means that it enhances images without sacrificing details, ensuring that every photo retains its natural look while becoming clearer and more defined.

One-Click Enhancement

With just a single click, Lupa AI converts your low-resolution images into stunning HD quality. This feature allows users to enjoy vibrant colors and sharp details instantly, making it perfect for social media posts or professional presentations.

Face Enhancement

The Face Enhance feature uses GFPGAN technology to specifically improve facial details in images. This makes it ideal for portraits, ensuring that facial features are enhanced while maintaining a natural appearance, perfect for both personal and professional use.

Multiple Resolution Options

Lupa AI offers various output resolutions, including 1K, 2K, 4K, 6K, and 8K. This flexibility ensures that users can choose the resolution that best fits their needs, whether for online use, printing, or other applications.

Reusable Contract Templates

Create a perfect contract template once and use it forever. Simply drag and drop date fields, text boxes, and signature blocks onto your PDF to build a customized template. Once configured, you can send this template an unlimited number of times to different recipients, saving you hours of repetitive work. This feature is perfect for standard agreements like NDAs, service contracts, or proposals, ensuring consistency and eliminating the risk of manual errors every time you need a new signature.

Batch Task Management & Sharing

Handle high-volume contract needs with ease using Zignt's batch management tools. You can prepare and send multiple contracts simultaneously, streamlining processes for large-scale operations like client onboarding or mass renewals. Sharing is seamless, offering both direct email delivery with automated reminders and convenient "Zignt Links"—shareable URLs that work like a payment link, but for getting contracts signed. This flexibility allows signers to choose the method that's easiest for them.

AI-Powered Renewal Tracking

Never miss a critical deadline again. Zignt's AI automatically scans your executed contracts to identify key dates like renewal deadlines and contract end dates. It then provides smart, customizable reminders so you can act well in advance. All upcoming renewals are neatly organized in a central dashboard, viewable by date, priority, or department, giving you complete control and visibility over your contractual commitments without any manual calendar tracking.

Legally Binding Security & Compliance

Every signature on Zignt is backed by enterprise-level security and meets international legal standards for enforceability. The platform is compliant with the E-SIGN Act, UETA, and eIDAS regulations. Each signed document comes with an automatic, court-admissible audit trail that records IP addresses, email timestamps, and signer details. Your data is protected with 256-bit SSL/TLS encryption (bank-grade), and Zignt adheres to GDPR, SOC 2, and ISO 27001 standards, ensuring full data privacy and security.

Restoring Old Photos

Every signed document includes a comprehensive audit trail with timestamps, IP addresses, and signer email verification, making it court-admissible and legally enforceable.

How does the unlimited signatures pricing work?

Zignt uses a simple, subscription-based model instead of charging per signature. You pay a fixed monthly or annual fee for your plan, which allows you to send an unlimited number of contracts for signing. This predictable pricing can lead to significant savings, especially for businesses with high-volume contract needs, compared to platforms that charge per document or per signer.

What is a "Zignt Link" for sharing?

A Zignt Link is a unique, secure URL generated for your contract, similar to a payment link from services like Stripe. Instead of sending a contract as a PDF attachment via email, you can simply share this link with your signers. They can click the link from any device, review the contract, and sign it immediately in their browser, making the process incredibly fast and convenient.

How does the AI renewal tracking feature work?

After you upload a signed contract to Zignt, our AI automatically scans the document text to find and extract key dates, such as renewal deadlines, termination dates, and important milestones. It then logs these dates in your renewal dashboard and sends you automated email reminders based on a schedule you can customize, so you're always prepared for upcoming actions.
