10 common design mistakes on AI-generated sites

The design mistakes that recur on AI-made screens, and how to fix each one.

AI-generated UI is fast but repeats predictable mistakes. These 10 patterns make a site look mass-produced — and most take minutes to fix.

  • Overusing purple→indigo gradients — swap for brand color
  • Centering everything — mix in asymmetric/left-aligned
  • Leaving the default font — set at least one custom font
  • Uniform radius/shadow — vary by hierarchy
  • Emoji-heavy headings — restrain; they cut professionalism
  • Overusing gradient text — one headline only
  • Too many hero effects (Beams + Spotlight + Aurora) — keep one
  • Meaningless stats/badges — numbers with no basis hurt trust
  • Neglected empty/error states — polish the screens users actually hit
  • Missing meta/favicon/OG — directly affects sharing and search

The order to fix them

If you can't change everything at once, start with the highest-impact. Color (1) and layout (2) alone shift half the impression. Then font (3), effect restraint (6, 7), and finally metadata (10) to lift search and share quality.
