Scanned 12 October 2026. 3 samples from Perplexity, round 9. 19 products recommended. Methodology v2026-09-29.1.

Counts, not percentages: with three samples a percentage would imply a precision the sample size cannot carry. “2 of 3” means the assistant recommended that product in two of its three answers to this question.
