Overview
Description

OpenCrab is an Ontology Graph RAG platform that extracts entities, relationships, evidence, and claims from documents to build source-cited ontology graphs. These graphs can be packaged into reusable ontology packs and queried through graph RAG or MCP-compatible AI tools like Claude, ChatGPT, Cursor, and Codex.

Pegasus AI is a workspace RAG chatbot platform that turns uploaded documents into operated AI assistants. Teams can create and manage chatbots, chat in the workspace, deploy a controlled website widget, connect scoped API clients, and track usage across personal and team contexts.
