iGPT is an Email Intelligence API that gives developers and AI builders structured, reasoning-ready context from email without building email parsing infrastructure from scratch.
Connect a user's inbox via OAuth (Gmail, Outlook, IMAP). iGPT indexes the full thread and attachment history, then exposes two endpoints. The recall/ask endpoint accepts natural language queries and returns structured answers with source citations. The recall/search endpoint runs hybrid semantic and keyword search with metadata filters.
What comes back isn't a summary. It's structured JSON: tasks with owners and deadlines, decisions with makers and timestamps, sentiment scores, risk flags, and citations linking back to source messages. Developers get intelligence their applications can act on without additional parsing or prompt engineering.
Use cases include CRM auto-enrichment from sales threads, customer health scoring from support conversations, automated meeting prep, invoice extraction from AP email, and workflow automation triggered by email decisions.
The Context Engine Framework handles thread reconstruction, quoted-text deduplication, participant role detection, attachment OCR, and multi-turn conversation logic. Quality tiers (normal, high, reasoning) are selected per API call. Retrieval runs at approximately 100ms with 3 seconds to first token on large inboxes.
Privacy and security are architectural: no training on customer data, no prompt or output retention, per-user isolation, AES encryption. Deployment options range from fully managed cloud to hybrid to fully private on-prem. SOC 2 and GDPR aligned.
SDKs available for Python and Node.js. Framework integrations include LangChain, LlamaIndex, and MCP.
