RAG Developer Tools
Every tool here solves a specific problem the ShopBot project hit in production — cost overruns, chunking errors, threshold guessing, injection risks. Use them on your own system, or follow the chapter link to understand exactly why each one matters.

RAG Cost Calculator
A paisa and a half per query sounds fine. At 50,000 queries a day, it is ₹750 daily. Enter your catalog size and volume — see the actual number before it surprises you.

Semantic Chunker Playground
How you split a product record determines what the retriever finds. Paste your data and see how identity, variant, care, policy, and FAQ chunks are generated — before you embed anything.
Book 1 · Chapter 6
Similarity Threshold Calibrator
Too low and you retrieve junk. Too high and you retrieve nothing. Drag the cosine similarity cutoff and instantly see which queries pass or get filtered — find the number that works for your data.

Prompt Injection Guard
A user who types “ignore all previous instructions” is testing your system right now. Paste any message and see whether your guard catches it before it reaches the model.
Each tool is from a chapter in Book 1 — The AI Engineer, which is completely free to read.
