How clearly do AI assistants understand a category? Every Friday we measure one — whether the answers it gives are settled, accurate, and anchored to the real market. One locked method, all year.
The Index asks whether AI assistants give a coherent account of a whole category — settled, accurate, and anchored to the real market. One category a week, the same instrument every time.
Whether it answers the same way twice, whether what it says is true, and whether its ranking matches the real category. Those three roll into one number from 0 to 100, and a word for which kind of clarity it is.
Where each brand lands is how we read the category. How clear the category is then decides whether that position can be moved, which is why the verdict matters more than the row.
Fifty-three symbols, one a week. The symbol belongs to the category, not to us — assigned when the category is scheduled, unique across the season, unchanged if we run it again.
Nearly every answer said the same thing: the bag dies at the wheels, the handle or the zipper, so the only question worth asking is who pays. That makes warranty fine print the deciding factor in this category.
