How a tier is earned
Transparent by design
01
Pick the use case
Every ranking answers one job - the best AI for blog writing, for cold email, for product photos.
02
Score five dimensions
Output quality, reliability, pricing, and two job-specific factors, weighted into a single 0-to-10 score.
03
Land in a tier
The score maps to S, A, B, or C. Below the bar, a tool stays out of the public ranking.
Funded by affiliate links. Never by placement. Every tier is earned by the score, and the score alone.
