Feature Comparison
iGPT
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.

Use Cases
iGPT
AI-Powered Email Assistants
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.

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.

Overview
About iGPT
iGPT is an enterprise-grade email intelligence API designed to solve a critical and costly problem: the failure of standard AI to understand the complex, unstructured data within business email communications.

Built for developers and enterprises, it serves teams building agentic systems, sales intelligence platforms, customer success tools, and compliance solutions that require deep, real-time insight from communication data. Its core value proposition is delivering trusted, context-aware answers from messy email data through a single, unified API call. This eliminates the traditional engineering heavy-lifting of parsing, chunking, indexing, and endless prompt tuning. Instead, iGPT offers a streamlined pipeline that handles intelligent retrieval, context shaping, and reasoning automatically. With a foundational focus on end-to-end security, granular access controls, and comprehensive audit trails, iGPT empowers businesses to deploy powerful, context-aware AI agents with confidence while maintaining strict data governance and compliance standards.
