How we test AI at ZDNET
ZDNET's AI reviews use real-world tests, not vendor benchmarks, to ensure fairness.
ZDNET's AI testing philosophy centers on hands-on, real-world evaluation with zero vendor influence. Products never get pre-publication review access, and the team prioritizes practical performance over synthetic benchmarks. Reviews come in two flavors: 'Best of' comparative lists that objectively rank top performers using documented standardized tests, and deep-dive personal stories that share long-term user experiences. This dual approach provides both broad category insights and granular product familiarity.
For comparative reviews, ZDNET follows a three-stage process: constructing evaluation criteria (covering performance, value, accuracy, safety, privacy), selecting candidate products (typically 5–10 from obvious leaders, reader requests, and community buzz), and running test-by-test comparisons. Each 'Best of' list includes a full test methodology appendix. Vendors pitching fee-based products are excluded from free lists, ensuring honest curation.

- Comparative 'Best of' lists use standardized test methodologies documented in each review for objective comparisons.
