Mobile web

68Fair

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture123
  1. Get a Demo button — Primary CTA sits well below the first viewport, pushed down by the badge, three-line headline, and four-line paragraph.
  2. YC badge pill — Oversized badge occupies a full band above the headline, spending prime fold space before the value statement.
  3. Body paragraph — Four long lines of copy delay the CTA; low-contrast text over the busy grid background hurts readability.

CTA

72Fair

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

Mentlio

Problems

  • demo = sales call, costly click
  • no self-serve or trial path
  • generic label, ignores headline promise

Value props

72Fair

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

Mentlio’s headline undersellsTake command of your AI velocitySee what AI costs, what it produces, and prove AI ROI. Mentlio measures locally, cuts token waste, and keeps prompts and source code on-device.

Working

  • Subhead names three concrete jobs
  • Hero dashboard shows real $ figures
  • On-device privacy claim is specific

Could improve

  • 'AI velocity' is a vague buzzword
  • Headline needs the subhead to parse
  • No number in headline or subhead copy

Information hierarchy

76Fair

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

Information hierarchy annotations on the desktop capture1234
  1. Research announcement banner — Top-of-page banner with a bold 'Read the research' link pulls the first click away from the demo path before the headline is read.
  2. Six-item nav row — Platform, Token Savers, Docs, Security, Blog, and Integrations sit at equal weight, giving six exit paths before the primary CTA.
  3. Get a Demo duplicate — The nav 'Get a Demo' duplicates the hero button at identical blue weight, splitting the single primary action into two competing targets.
  4. Dashboard preview cropped — The product screenshot enters the fold as a thin sliver, showing partial stat cards that add visual noise without communicating the outcome.
