Code Explainer is not built yet

We publish the whole catalogue before we build it, so you can see where this is going and tell us what to prioritise. This page will become the working tool - the URL will not change, so a bookmark now still works later.

What happens to your data

Your text is redacted before it reaches any AI model: name, email, phone, address and date of birth are replaced with tokens first. The model reads your document and writes the explanations; it never chooses a number - every score is arithmetic over a fixed rubric in our own code. One input to that arithmetic is the model's reading of which skills you evidence, so we store your result and re-running the same input returns it rather than a fresh one. We never invent a figure your own material does not contain.

Credits are a licence to use these tools - not money, not transferable. Full detail in our privacy policy and AI policy.

While you wait

A person can explain the codebase, not just the snippet
