CTA

44Poor

Copy, size, verb, cost-feel — does the primary CTA earn the click?

Problems

  • no button or in-product action
  • nav cards are nouns, not actions
  • bare arrow icons, no payoff promised
  • one card says 'Coming soon'

Mobile web

58Fair

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture12
  1. Headline pushes cards down — The hero headline starts halfway down the viewport, leaving no room for a tappable action in the first fold.
  2. Arrow-only tap targets — Each section's action is a small thin arrow glyph, far below thumb-friendly size and easy to miss or mis-tap.

Value props

62Fair

Title, subtitle, hero — do they sell the product's true value?

Paper Instruments’s headline undersellsOpen-source frontier models for knowledge work

Working

  • Names category and audience plainly
  • Open-source is a real differentiator
  • No buzzword stack; reads credible

Could improve

  • No subhead or proof under the H1
  • Zero numbers or benchmarks in fold
  • Hero art decorates, shows nothing

Information hierarchy

68Fair

Does the design help or inhibit what the page is trying to say?

Information hierarchy annotations on the desktop capture123
  1. Four equal-weight cards — Four identical arrow links share the same visual weight, so no primary action exists and attention splits four ways.
  2. Feather/Ultramarine row cropped — The second card row is cut by the fold with its descriptions hidden, leaving two half-legible destinations.
  3. Ultramarine underline accent — The blue scribble makes Ultramarine the only accented element without explaining why it deserves priority.
