iGPT vs Zignt

Unified Intelligence Endpoint

Replace complex, multi-step retrieval architectures with a single API call. iGPT consolidates the entire process—from understanding your natural language query to retrieving relevant data across emails and attachments, shaping the optimal context, and delivering a reasoned response—into one streamlined pipeline. This eliminates the need to manage separate systems for parsing, vector stores, and prompt chains, dramatically accelerating development.

Deep Email & Attachment Processing

iGPT goes beyond simple email text. It automatically and deeply indexes the full content of email conversations, including reconstructing threads across time and participants. Crucially, it processes attachments—extracting text, data, and structure from documents, PDFs, and spreadsheets—to understand the complete context of a communication, ensuring no critical information buried in a file is missed.

Context Engineering Framework (CEF)

This proprietary system automatically optimizes how context is retrieved and presented to your LLM. It employs hybrid retrieval (semantic, keyword, and filters), scores and re-ranks results, and shapes the context window specifically for your query. This means developers get high-quality, relevant context without the manual, iterative work of prompt engineering and tuning, leading to more accurate and reliable agent outputs.

Enterprise-Grade Security & Governance

iGPT is built with strict compliance and data control in mind. It features a zero-data training policy, ensuring your data is never used to improve models. It offers Role-Based Access Control (RBAC) with OAuth enforcement, processes data in memory with zero retention, and provides a full audit trail for every request. This allows enterprises to leverage powerful AI while keeping data securely within their control.

Reusable Contract Templates

Create professional contract templates once and use them an unlimited number of times. Simply drag and drop signature blocks, date fields, and text boxes onto your PDF to configure it. This feature eliminates the need to rebuild the same document repeatedly, saving hours of manual work on every contract and ensuring consistency across all your agreements.

Instant Sharing & Multiple Signing Options

Send contracts for signature seamlessly through direct email with automated reminders or by generating a secure Zignt Link—similar to a payment link. This flexibility caters to all signer preferences. You can also optionally enable ID verification for added security and allow signers to choose between typed or drawn handwritten signatures for a personalized touch.

Build intelligent agents that can draft, prioritize, summarize, and act on email with full historical and attachment context. Instead of agents working in a vacuum, they can understand the entire conversation thread, participant sentiments, and referenced documents to generate highly relevant and actionable responses, turning your inbox into an automated productivity hub.

Customer Support & Success Copilots

Empower support teams with agents that instantly rebuild the complete customer story. By analyzing long email chains, attachments, and subtle tone shifts, iGPT provides copilots with a unified view of the issue history, past resolutions, and outstanding commitments. This leads to faster, more personalized support and higher customer satisfaction.

Sales & CRM Intelligence Automation

Automatically extract crucial deal intelligence directly from email threads. iGPT can identify key decisions, action items, owners, deadlines, and changes in deal momentum that are often communicated informally over email. This data can be pushed to CRM systems, giving revenue teams real-time, context-rich insights without manual entry.

Compliance & Audit Trail Generation

Automate the tracking of approvals, feedback, and rationale buried in email communications. iGPT can trace specific decisions or statements back to their source messages and attachments, creating a verifiable audit trail. This is essential for legal, financial, and regulatory compliance, saving countless hours of manual email discovery.

Streamlining Sales Agreements

Sales teams can close deals faster by sending proposals and sales contracts instantly via a link or email. Using pre-built templates ensures all necessary terms are included, while real-time tracking lets reps see when a document is viewed and signed, allowing them to follow up proactively and accelerate the revenue cycle.

Managing Vendor & Supplier Contracts

Operations and procurement teams can efficiently onboard new vendors and manage ongoing supplier agreements. Reusable templates standardize terms, and the centralized dashboard provides visibility into all active contracts. AI renewal reminders prevent auto-renewals from slipping through the cracks, optimizing costs and relationships.

Automating HR & Onboarding Paperwork

Human Resources departments can simplify the employee onboarding experience. Offer letters, NDAs, and policy acknowledgments can be prepared as templates and sent digitally. New hires can sign documents from any device, and completed copies are automatically filed, creating an organized, searchable digital record for compliance.

Handling Client Service Agreements

Freelancers, agencies, and consultants can professionally manage client engagements. They can quickly generate a legally binding statement of work or service contract from a template, share it via a client-friendly link, and receive the signed copy back in minutes, reducing administrative back-and-forth and starting projects faster.
