Feature Comparison

iGPT

Unified Intelligence Endpoint

Replace complex multi-step pipelines with one simple API call. iGPT's single endpoint handles retrieval, context shaping, and reasoning in a unified, blazing-fast pipeline. You provide a natural language query, and it returns a structured, cited answer—bypassing the need for separate vector stores, parsing logic, and fragile prompt chains. This streamlined approach slashes development time and operational overhead.

Real-Time Ingestion & Thread Reconstruction

iGPT indexes new messages and attachments instantly, ensuring your AI agents always operate on the latest data. It doesn't just read individual emails; it automatically reconstructs full conversation threads across time, participants, and attachments. This provides agents with the complete narrative context, crucial for understanding nuanced discussions, decisions, and action items.

Advanced Attachment Processing

Go beyond email body text. iGPT deeply processes attachments—including documents, PDFs, and spreadsheets—extracting text, data, and structure. This intelligence is seamlessly integrated with the email thread context, allowing queries to surface insights from contracts in an update or figures from a report, all within the conversational flow.

Enterprise-Grade Security & Audit

Built with zero data training, zero data retention, and strict OAuth-only Role-Based Access Control (RBAC). Every inference is processed in memory and never stored, ensuring your sensitive communications never leak. Full audit trails make every response traceable back to its source, providing the compliance and trust required for enterprise deployment.
