C3 · Plain words
One of the 18 tests every grill uses. Clarity is 35% of the score.
The test, as the critic reads it
Is the headline free of invented nouns, category jargon and adjectives doing the work of facts? ("Seamless", "powerful", "AI-driven", "next-gen" fail this on sight.)
It is scored pass, partial or fail, and it can be marked as not applying. Every finding filed under it quotes the page. The whole checklist is on one page.
How real pages did
Of the 23 public launches judged on it, as of 1 Oct 2026: 20 passed, 1 partly passed, 2 failed. That is a small sample, from the record, not a survey.
