## 概要

iGPT is a context engine and developer API that turns company email threads, attachments and connected knowledge into retrieval-ready context for AI agents and automation workflows. One unified endpoint handles ingestion, hybrid retrieval, thread reconstruction and cited answers so teams can ship agents without maintaining their own parsing, chunking, indexing or prompt-tuning pipelines.

## 料金とプラン

iGPT does not publish a simple public price on its homepage. The site features a dedicated Pricing page plus a "Book a demo" and "Get your API key" flow, and enterprise deployments (hybrid, private cloud, on-premises) are arranged with the team. Check the official pricing page for current usage-based rates and plan tiers.

## 主な機能と特長

- **Email intelligence API:** Turn raw email threads and their attachments into structured, cited context that a language model can reason over immediately.
- **One unified endpoint:** A single natural-language request replaces multi-endpoint retrieval, running recall, context shaping and answer generation in one pipeline.
- **Hybrid retrieval with reranking:** Semantic and keyword search are combined, filtered and reranked in a single call for higher-precision results.
- **Thread reconstruction and citations:** Threads are rebuilt across time, participants and attachments, and answers always link back to the source messages.
- **Realtime, permission-aware indexing:** Realtime indexing of new messages and OAuth-based, permission-aware access keep answers current without exposing content a user cannot see.

## 主なユースケース

- **Ship an email assistant (Developers):** Build assistants that draft, prioritize and act on mail using the full history of a thread and its attachments.
- **Automate workflow extraction (Automation teams):** Turn conversations into tasks, deadlines and approvals, and surface what is stuck, without hand-built parsers.
- **Power support copilots (Support organizations):** Reconstruct a complete customer story across long chains and tone shifts to give support agents reliable backing context.
- **Feed CRM and compliance agents (Revenue ops):** Extract decisions, owners and deal momentum from threads to keep CRM records accurate and traceable.

## 強み

- Purpose-built for email and attachment context, not generic document search
- Single endpoint removes a lot of retrieval plumbing work for developers
- Cited, permission-aware answers with an audit trail suit regulated and enterprise teams
- SDKs plus MCP and LangChain integrations fit existing agent stacks
- Reports lower token cost than a comparable Gmail-agent approach on the same model

## 制約・デメリット

- Enterprise-oriented positioning means the free/self-serve experience is limited compared with consumer AI tools
- Value depends on having meaningful email/attachment data to index; thin mailboxes see less benefit
- On-premises and fully private deployment require a sales conversation and custom quoting
- It is one piece of a larger stack, so teams still need their own LLM and orchestration layer

## よくある質問

### What exactly is iGPT?
iGPT is a context and email-intelligence API for developers and enterprises. It indexes email threads and attachments and returns structured, cited, reasoning-ready context that AI agents and workflow tools can consume, instead of raw email data the model has to figure out.

### How much does iGPT cost?
Pricing is not published as a simple self-serve number on the homepage; the site lists a Pricing page and a "Book a demo" path for teams. Start on the official pricing page or speak with the iGPT team for current tiers, usage rates and enterprise options.

### How does the context engine work?
The stack includes real-time ingestion of new messages and attachments, hybrid semantic plus keyword retrieval with reranking, automatic email thread reconstruction, context shaping for the target LLM, permission-aware retrieval that respects each user's mailbox scope, and answers that cite their source messages.

### What about data security and privacy?
The site states zero data training (data is never used to train models), OAuth-only processing with role-based access control, zero data retention during inference, and a full audit trail, with cloud, hybrid and fully private deployment options.

### Can I integrate iGPT with my own stack?
Yes. SDKs are available for Python and cURL, with integrations for MCP and LangChain, and a live playground for testing requests against real data before shipping.
