Feature Comparison
iGPT
Unified Intelligence Endpoint
iGPT consolidates the entire process of email intelligence into a single API call. This eliminates the need for developers to build and maintain separate systems for retrieval, context shaping, and reasoning, a common challenge noted in complex RAG implementations. A user simply submits a natural language query, and the API handles deep indexing, hybrid retrieval, and optimized context preparation automatically, returning a structured response with citations in approximately 3 seconds to the first token.
Deep Contextual Understanding & Thread Reconstruction
The API goes beyond simple keyword matching by semantically understanding email content and its relational context. It automatically reconstructs fragmented email threads across time, participants, and related attachments, rebuilding the complete narrative of a conversation. This capability is crucial for accurate understanding, as critical information is often distributed across multiple messages and replies, a nuance that standard search fails to capture.
Advanced Attachment Processing
iGPT extracts and indexes text, data, and structural information from a wide array of attachments, including documents, PDFs, and spreadsheets. This processing is performed in the context of the surrounding email thread and its participants, allowing the system to answer questions about contract clauses, invoice details, or report figures as they were discussed, turning static files into queryable knowledge assets.
Enterprise-Grade Security & Compliance Framework
Built for regulated industries, iGPT enforces a strict security model. It guarantees zero data training or retention, with all inferences processed in memory. Access is controlled via OAuth-only processing with Role-Based Access Control (RBAC), and every response includes a full audit trail, linking answers directly to source messages. This ensures data sovereignty and compliance with stringent data protection standards.
