Visual GraphRAG chat app. Build a knowledge graph on a canvas, save it to Neo4j, and ask questions in plain English. Answers come from vector search plus live graph traversal.
Rehbar AI offers Applied AI for Beginners, a free 5-day, 12-chapter course that teaches applied AI and guides learners to build their own GraphRAG app. The course starts from basic LLM concepts and progresses to an AI that answers questions from a knowledge graph the learner builds. The practice app, GraphRAG Chats, is open source and runs locally with Docker using free AI models. Learners finish with GraphRAG Chats running on their machine, a graph they built, and an understanding of how an LLM turns search results into answers. The course is designed for beginners who can use a terminal and read a little Python, and it states that no maths or machine learning background is needed. Completing all 12 chapters earns a certificate of completion with the learner's name.
