## Mobile web — 58, Fair

The mobile review treats the phone experience as a first-class citizen.

![Mobile web annotations on the mobile capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/paperinstruments.com-mobile.jpg?v=2026-09-23T00%3A43%3A06.935%2B00%3A00)

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 — 62, Fair

This category asks whether the title, subtitle, and hero sell the product’s true value.

### Headline

> **Open-source frontier models for knowledge work**

The report says the headline **undersells** the offer.

**Working:**

- Names the category and audience plainly
- Open-source is a real differentiator
- Uses no buzzword stack and reads credibly

**Could improve:**

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

6. [AI21 Labs — 38](https://www.lazyweb.com/growth-score/site/ai21.com)

## Information hierarchy — 68, Fair

This category asks whether the design helps or inhibits what the page is trying to say.

![Information hierarchy annotations on the desktop capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/paperinstruments.com.jpg?v=2026-09-23T00%3A43%3A06.935%2B00%3A00)

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.
