Reading level

How hard a text is to read, based on word and sentence difficulty; it should match the reader's age and background.

Say it to an AI

Explain compound interest to a 12-year-old who just got £50 for her birthday and wants to spend it all. Use her £50 as the example, no formulas or jargon, and keep it to a few short paragraphs she can read herself.

How an expert would ask for the stronger version of “Explaining compound interest”.

A parent asks an AI assistant to explain compound interest so they can pass it on to their daughter.

Study A · the stronger one
Study B · the weaker one

Why: A's reply uses short sentences and '£50 in a savings account'; B's uses 'the principal', '5% AER' and 'compounding periods per year'.
