AI Use Policy

AI never decides your numbers

Every tax, benefit, property, and finance figure on this site is produced by a deterministic rules engine - defined formulas and thresholds evaluated the same way every time. AI is not used to calculate an amount or to decide whether you qualify for anything. See our Methodology.

Where AI is used

• Practice question generation - the Math Quiz feature can use a large language model (Groq) to generate practice arithmetic questions. If the model is unavailable, a deterministic generator is used instead. This feature does not affect any calculator result.
• Plain-language help and translation (where offered) - AI may be used to rephrase or translate an explanation. It never changes the underlying figure.

Human oversight

Editorial content and calculator rules are written and reviewed by people against official sources. AI-assisted helper output is clearly secondary to the deterministic result.
