GRADE C
BAND 56–76

What their homepage claims

“Sketch · Design, prototype, collaborate and handoff”

What that means

Sketch is a design tool for creating UI designs, building interactive prototypes, collaborating with teammates, and delivering assets to developers.

Verdict

Overall, the page communicates what it sells clearly enough to justify a mid-level clarity score, driven by concrete numeric claims and strong CTAs, but relies on abstract phrasing in the headline.

What to fix first

Ranked by what each change is worth on the composite — the gap to the next rung of the ladder times the dimension’s weight. Computed from the scores, not written by the model; the model’s sentence under each is the action.

  1. 1Clarity quick win 50 → 65+4.5

    Use a concrete product noun in the headline, e.g., "Sketch: UI design software" or similar.

  2. 2Call to action quick win 80 → 95+2.3

    Place a single explicit CTA under the measurable claim.

  3. 3Proof needs a fact 5 → 20+2.3

    Include a verifiable metric or named customer logos with numbers.

All three together: 66 → 75. Every dimension one rung up: 75 (grade B). Ceiling is 95.

“Sketch: a design tool for designing UI, prototyping, collaborating, and handing off to developers.”

Built only from facts already on the page — not the company’s words. Shown so the gap between what was written and what could have been written is concrete rather than a number.

I owe a tremendous debt of gratitude to Sketch. It is easy and wonderful and graceful enough that I can use it easily in my workflow with Ben. Legitimately a really wonderful utility.

The foundational features of Sketch have been indispensable. I also like using it while flying and traveling, and the fact it’s a native app makes designing more enjoyable overall.

Sketch allows me to design with little limitation. The plethora of features it offers and quality of life improvements in recent updates make working with it a delight.

I’ve been a Sketch user since version 1.0. I love the simplicity of Sketch’s UI and its robustness. Making it our own makes designing a pleasure and saves tons of time.

Strongest: Specificity 95. Weakest: Proof 5. The 4 passes agreed within 20 points. The band 56–76 is where a re-score of this unchanged page would most likely land: on 42 dry re-scores (12 Oct 2026) the median move was 6 points and one in four moved more than 10. A grade only changes when a new score clears the boundary by 5.

Nothing struck

No word in the headline itself was judged empty. That is rare: 12 of 128 companies in the index manage it.
