Our AI answer product relies on publishers' content, and they want to be paid. Flat licence, per-use payment, revenue share, or nothing?

Pay for content that measurably improves answers, in the form that matches how you use it: per use for grounding, flat licences for unique training data, and nothing for sources that don't move quality.

Updated Nov 2026 · Original practice questions with worked answers and teaching rubrics. Our editorial policy explains the sources, review process and limits.
