CustomGPT.ai RAG for Claude Code

Enterprise-grade RAG directly in your terminal. Query your organization's knowledge bases, runbooks, specs, and documentation without leaving Claude Code.

The Problem

You are debugging a production issue. You need to know:

What does the runbook say about database failover?
What is our rate limiting policy?
How is the auth service supposed to handle token refresh?

Without this plugin: Alt-Tab to browser. Search Confluence. Scroll through Notion. Find the wrong version. Lose context.

With this plugin: Ask directly in your terminal. Get the answer with citations. Keep your flow.

Instant RAG Queries

Query your documentation directly:

PII must be encrypted at rest using AES-256 and in transit using TLS 1.3.

Source: data-handling-guidelines.pdf (Page 12)

Automatic Retrieval

Claude autonomously queries your docs when you ask about:

Company policies and procedures
Internal documentation or runbooks
Technical specifications

Just ask naturally:

"Update this code to follow our error handling guidelines"

Claude will fetch the relevant documentation and apply it.

Citation Support
