Nine principles, applied to your page
Focus, human units over specs, experience before technology, one decision, showing the product, and craft in the details nobody would have checked. Every finding has to point at something really on the page.
Get the verdict and what to cut
Most findings make the page smaller. You get the list of what to remove, the claim to lead with, and the one button worth keeping.
Landing pages rarely get worse in one decision. They get worse the way a desk gets messy: a section for the new feature, a badge for the award, a banner for the webinar, a second button because two teams each wanted their own. Every addition was reasonable and nobody is ever assigned to take something away.
Focus is the discipline of subtraction, and it is the hardest thing to do to your own page because you know why each piece is there. An outside reader does not, and simply asks what all of this is for.
The famous version is a hard disk described as a thousand songs in your pocket. The principle underneath is that a specification is an answer to a question the reader did not ask. They do not want five gigabytes, ninety-nine point nine nine percent uptime, or unlimited seats — those are facts about your system. What they want is what those facts do for them, and most pages leave that translation as an exercise.
This review reads the styles your browser actually resolved, not just a screenshot. When it says your page renders five heading sizes with no system, that is counted from what shipped. A model looking at an image can only guess at that, and a guessed measurement stated as a finding is worse than no finding, because it is indistinguishable from a real one.
The Paul Graham review asks whether the page is clear, honest and built for someone specific. This one asks whether it decided what to be. They disagree often, and where they disagree is usually the most interesting thing anyone will tell you about your page.
No, and the tool will not claim otherwise. He published no body of writing, so this lens is assembled from the public record — keynotes, on-stage interviews, and Apple's own published design copy. It is an interpretation of a documented approach to products, made by us. It never writes as him, never states what he would have said, and never invents quotations. If you want a lens built from someone's own prose, the Paul Graham review is exactly that.
