HOW IT WORKS

What it checks, and how to read the result.

WHAT IT CHECKS

  • Blu, our AI, reads what a first-time visitor takes in: the page title and description, the headings, the navigation, the button labels and the start of the visible text.
  • It answers four questions: what it noticed first, what it understood, what it never saw, and the one fix to make first. Then it rates clarity from 1 to 10.

HOW TO USE IT

  1. 1Enter the page you want judged. Your homepage, or a landing page for a campaign.
  2. 2Read the four answers and the clarity score.
  3. 3Change the page, then run it again to compare. You get three glances a day.

READING THE RESULT

  • If what Blu “understood” isn't what you sell, the page has a message problem, not a design problem.
  • “I never saw” usually points at something important placed too low or worded too vaguely.

WHAT IT DOESN'T DO

  • Blu reads the structure and the words, not pixels. It doesn't see your images, colours or layout.
  • Content added later by JavaScript isn't seen.
  • It is one simulated visitor with no context about your market. Real users can see it differently.

AN HONEST NOTE

Blu is one visitor, not your users.

A five-second test — human or AI — measures first impressions, nothing deeper. Blu won't know your market, your traffic source or your brand history. What Blu is good at: saying the thing your team stopped seeing two years ago, in about five seconds.
