Frequently asked questions
Which AI and ML concepts are explained?
RAG, vector databases, embeddings, context engineering, LLM evals, agent memory and more — each in one plain-English guide.
Do I need a machine learning background?
No. Explainers assume no prior ML knowledge and use diagrams and analogies before jargon.
Do the explainers include code?
Where it helps. Each guide pairs the concept with a small, runnable example.
