Blobs are what a generator draws when asked for a picture and given none. They cost nothing, mean nothing and look like every other page in the category. A strong tell because it is rarely anyone’s request; it is what fills a hero that has no picture.
Builders whose defaults include this one
An entry names a builder only when its fingerprints are visible; this tell is one of them for Bolt.
Other tells in visual style
- Glass panels: Semi-transparent panels with a backdrop blur and a thin light border, stacked over a gradient so there is something to blur.
- Gradient text: A headline, or one word in it, filled with a colour gradient and clipped to the letters.
- Inter or Poppins, untouched: The page is set in Inter, Poppins or the framework default at the default sizes, with no type decision visible anywhere.
- Permanent dark mode: A near-black page for a business that has no reason to be in the dark: a bakery, a physiotherapist, a tax advisor.
- Rounded corners on everything: Cards, buttons, images, inputs and badges all share one large corner radius, usually the framework's largest preset.
- Second-generation tasteful defaults: Cream with terracotta, or near-black with acid green, applied as the automatic answer to "don't make it look like AI".
- The italic serif accent word: One word of the headline set in an italic serif, the rest in a sans, as the single "designed" touch on the page.
- The purple gradient: A hero background or button that fades from indigo to violet to pink, the house colour of the 2024 to 2026 AI builder generation.
