Interactive RAG Pipeline Simulator

Experience full RAG: upload text, configure chunk size and overlap, generate mock embeddings, perform vector search, and synthesize answers.

Architecture Breakdown: Semantic Search & Context Augmentation

1. The Open-Book Exam

Standard ChatGPT takes an exam from memory. If it forgets a fact, it guesses (called hallucinating). RAG turns it into an open-book exam: it looks up your exact PDF or handbook first, then answers truthfully.

2. Chunking & Searching

You can't fit a 500-page book into one question. RAG chops the book into bite-sized paragraphs (chunks) and uses semantic search to find the top 2 or 3 paragraphs that match what you asked.

3. Try Asking Below!

Click "What is the home internet stipend?" below. Watch the system search through the employee handbook, pull out Chunk #1 ($80/mo), and synthesize the grounded answer!
