iGPT vs Zignt

Unified Contextual Endpoint

Replace complex multi-step retrieval systems with a single natural language API request. iGPT's unified endpoint seamlessly handles retrieval, context shaping, and reasoning in one integrated pipeline, delivering answers ready for automation without any prompt engineering or manual pipeline management required.

Deep Email & Attachment Processing

iGPT automatically and deeply indexes all email data, including complex threads with multiple participants. It also processes attachments, extracting text, data, and structure from documents, PDFs, and spreadsheets to provide a complete view of the conversation's context and content.

Hybrid Retrieval with Citations

The system employs a sophisticated hybrid retrieval method combining semantic, keyword, and filtered search, which is then scored and re-ranked in one call. Every answer is returned with direct citations back to the source emails and attachments, ensuring verifiability and trust.

Enterprise-Grade Security & Auditability

Built with strict security principles, iGPT offers zero data training, OAuth-only processing with Role-Based Access Control (RBAC), and zero data retention. Each inference is processed in memory, and a full audit trail ensures all actions are traceable, keeping data under your company's control.

Reusable Contract Templates

Create a contract template once and use it unlimited times. Drag and drop date fields, text boxes, and signature blocks onto your PDF to configure it in minutes. This feature saves hours of repetitive work, ensuring consistency and eliminating the need to rebuild the same document for every new agreement.

AI-Powered Renewal Management

Never miss a critical deadline. Zignt's AI automatically scans your contracts to detect renewal dates, end dates, and important milestones. It provides smart reminders and a centralized dashboard to view all upcoming renewals, allowing you to stay organized and proactive without manual tracking.

Secure & Flexible Sharing

Send contracts seamlessly via email with automated reminders or share a simple Zignt Link—similar to a payment link. You can optionally require ID verification before signing and offer multiple signing methods, including typed or handwritten signatures, to reduce friction for all parties involved.

Legally Binding Audit Trail

Every signature is backed by a comprehensive, court-admissible audit trail. This is automatically generated and includes timestamps, IP addresses, email addresses, signer names, and any ID attachments. This ensures full legal compliance and traceability for every document signed on the platform.

Intelligent Email Assistants

Build AI agents that can draft, prioritize, summarize, and act on emails with a complete understanding of the entire thread history, participant roles, and attached documents, dramatically improving productivity and response quality.

Customer Support Copilots

Empower support teams with agents that instantly reconstruct the full customer story across long, messy email chains. These copilots can understand tone shifts, track issues, and reference attachments to provide accurate, context-rich support.

Workflow & CRM Automation

Automatically turn email conversations into structured data for other systems. Extract action items, deadlines, approvals, and deal momentum to create tasks in project tools or update records in CRM platforms like Salesforce, directly from email threads.

Compliance & Audit Trail Generation

Automate the tracking of critical communications for legal and regulatory compliance. iGPT can trace feedback, decisions, approvals, and rationale back to the original email and attachment sources, creating a reliable and searchable audit trail.

Sales Teams Closing Deals Faster

Sales professionals can instantly send proposals, NDAs, and service agreements using pre-approved templates. With instant links and automated reminders, they accelerate the sales cycle, get signatures in minutes instead of days, and keep the pipeline moving without administrative delays.

HR Onboarding & Employee Documentation

Human Resources departments streamline the onboarding process by sending offer letters, confidentiality agreements, and policy documents electronically. Bulk sending and team collaboration features make it easy to manage high-volume hiring while maintaining security and compliance.

Legal Teams Managing Contract Lifecycles

Legal counsel and operations teams use Zignt to maintain control over contract templates, collaborate on revisions, and manage the entire signing process. The AI renewal tracker and secure audit trail provide essential oversight and risk management for all corporate agreements.

Freelancers & Small Business Owners

Independent professionals and small business owners can present a polished, professional image by using Zignt for client contracts, statements of work, and invoices. The free plan and lack of per-signature fees make it a cost-effective solution to legally secure agreements without overhead.

iGPT is an enterprise-grade email intelligence API that transforms the unstructured data within email communications and attachments into structured, actionable intelligence for AI agents and automated workflows. It solves a critical gap where most AI systems fail: reliably accessing and understanding the complex context of email threads, documents, and historical conversations. Designed for developers and enterprises, iGPT provides a secure, unified gateway to deep email context through a single API call. This eliminates the immense engineering burden of building and maintaining custom pipelines for parsing, chunking, indexing, and prompt tuning. By delivering trusted, context-aware answers with full citations, iGPT enables businesses to confidently deploy intelligent automation for sales, customer support, operations, and compliance, turning the chaos of email into a powerful, structured data source.

How does iGPT handle data privacy and security?

iGPT is built on a foundation of enterprise-grade security. It practices zero data training, meaning your data is never used to train models. It uses OAuth-only processing with RBAC, enforces zero data retention (processing happens in memory), and provides a full audit trail, ensuring data never leaves your control.

What makes iGPT different from using a generic LLM on email text?

Generic LLMs lack the specialized understanding of email structure, threading, and attachment context. iGPT provides a complete pipeline that deeply indexes, reconstructs threads, processes attachments, and performs optimized retrieval to deliver accurate, cited answers from messy email data through one simple call, eliminating months of custom engineering.

Can iGPT process data from multiple email sources?

Yes, iGPT is designed to connect to and unify data from various enterprise email sources. It deeply indexes emails and attachments from these connected sources, allowing a single API query to retrieve context from across all of them, creating a unified intelligence layer.

What is the Context Engineering Framework (CEF)?

The Context Engineering Framework (CEF) is iGPT's performance and quality tier system. It allows developers to choose the optimal balance of speed, cost, and reasoning depth for their specific use case by selecting different CEF tiers (e.g., cef-1-normal) when making an API request.

Is Zignt legally binding?

Yes. Zignt signatures are legally binding and compliant with major international regulations, including the E-SIGN Act (US), UETA, and eIDAS (EU). Every signed document comes with a court-admissible audit trail that records all necessary compliance data.

How does the unlimited signatures model work?

Zignt does not charge per signature. You pay a subscription for access to the platform, and then you can send documents for signature an unlimited number of times to an unlimited number of signers, which can lead to significant cost savings compared to pay-per-signature models.

What security measures are in place?

Zignt employs bank-level security, including 256-bit SSL/TLS encryption for all data in transit and at rest. The platform is SOC 2 compliant, GDPR ready, and follows ISO 27001 standards, ensuring military-grade protection for your sensitive contracts and data.

Can I use my own contract PDFs?

Absolutely. You can upload any PDF contract directly into Zignt. Then, use the drag-and-drop editor to quickly add signature blocks, initial fields, text boxes, or dates before sending it out to your recipients for a seamless signing experience.
