How to use AI Engineering Hub

1. Open the Tokenizer Playground tab and paste any text, then press Analyze text to see word, character, and subword counts.
2. Try the BPE-style merge demo with a word like learning to watch single characters merge into tokens step by step.
3. Open the RAG Explainer tab and walk the four steps: chunk, embed, retrieve, generate.
4. Type a question, press Retrieve and draft, and read the ranked sample passages plus the grounded draft answer.
5. Open the Agent Workbench tab and tick the checklist items across goal, tools, memory, evals, and guardrails, then download the finished checklist.
