Side by side

Pretty is not ready.

The picture can look as good, or better. It still has to be the ad.

Easy to see

Transparent Labs · Protein Coffee

The tub is blank. No logo.

Easy to miss

Asarai · Earth Tones

The logo and the button sit outside the safe zone.

Every ad

The checks

What ready means

Miss one check, and the ad is not ready.

  • Product

    The real product, in the pack you sell. A lookalike fails.

  • Logo

    The brand's logo, copied exactly. A redraw fails.

  • Font

    The brand's typeface, not a similar font.

  • Safe zone

    Logo, copy, and product stay clear of the edges, where buttons and captions sit.

  • Language

    The words are in the language of the request.

  • Claims

    No claim the brand did not make.

  • Gibberish

    Text is real words, not garbled letters.

  • Text

    The ad has the text it was supposed to have.

  • Anatomy

    People and objects are drawn correctly.

How it's judged

Three anonymous judges. Same bar for every app, including Omneky.

The ChatGPT and Gemini runs used their APIs with the same tools the apps use (web search and image generation). Spot-checks in the ChatGPT and Gemini apps gave similar results.
