Designed, or just defaulted?
Paste a link to a page or upload an image of your design. You get a score from 0 to 100 for how generic it looks, and a fix for each sign we find.

A look inside the critique
Example
An example result
fieldwork, a made-up studio · landing page
Example slop score 38out of 100
Mostly deliberate
A few default choices are left.
Medium impact · Above the headline, top left
The small capital letters say nothing that the headline does not already say. Templates have a label here, so the page starts to look like a template.
How to fix: Remove the label, or give it a real job, such as the studio's city or the year it opened.
High impact · Under the intro text
The only button is small and pale green on cream. The next step is hard to find, and its white text is hard to read.
How to fix: Make the button larger and give it one strong colour that the page uses only for actions.
Low impact · Caption on the illustration, bottom left
“Space to belong” could sit on a hotel, a bank or a gym. It says nothing about this studio.
How to fix: Replace it with one specific line about the studio's work, such as a real project and its place.
This is a made-up page that we drew to show how a result reads. Slop Check did not score it.
Defaults aren’t the problem. Unconsidered ones are.
A gradient can be the right choice. So can one font. What matters is whether the choice suits your product. Slop Check looks for choices that repeat across many AI-made screens. It explains why each one looks generic and how to fix it.
Learn to see the defaults
The Slop Index names the 12 signs Slop Check looks for, with a fix for each one. Here are three.
01 · Typography
One default font for everything
The logo, headline and buttons all use the same plain sans-serif font.
What to look for
The logo, headline, body text and buttons all use one plain sans-serif font, often Inter or the system font, usually bold and tightly spaced. It is never wrong, and that is the problem: the type says nothing about the product.
How to fix: Use a font with more character for headlines, such as a serif or a sans-serif with unusual shapes. Keep the plain font for small text. Use two fonts, each with one job.
02 · Composition
Three cards with icons in coloured circles
Three identical cards, each with an icon in a pale coloured circle.
What to look for
Three identical cards with rounded corners. Each has an icon in a pale circle, a short bold title and a line of grey text. People see "a list of features" before they read any of the text.
How to fix: Let the content decide the layout. Try one large feature with two small ones, a simple list, or a real image of the feature working.
03 · Colour
Purple-to-blue gradient
A gradient does the job a brand colour should do, often with a round button on top.
What to look for
A purple-to-blue gradient sits behind centred white text and a round button. It became common because it looks finished without anyone choosing a colour.
How to fix: Choose one brand colour that comes from the product or its subject, and use it to point at what matters. To set a mood, use a real photo or a strong layout instead of a gradient.

A starting point.
Save the designs you like. blends adds tags to each one. Then it turns any group of them into a DESIGN.md file that your AI coding tool can read, so your next screen starts from your taste, not from a default.
We will send one email when it launches. Nothing else.
Common questions
Is it free?
Yes. You do not need an account. Each visitor can do 3 checks in any 24 hours. Checks that fail also count. This keeps the tool free to run.
What can I check?
One public page from a website link, or one image of a screen: PNG, JPG or WebP, up to 4 MB. A landing page, an app screen, a poster or a slide. For a link, we check only that one page.
Is the score a verdict on my design?
No. It is a reason to look again. A lower score is better. A choice that looks generic can still be right for your product, so read the reasons, not only the number.
- 0–19
- Clearly designed. Every choice looks intentional.
- 20–39
- Mostly deliberate. A few default choices are left.
- 40–59
- Some defaults showing. The template shows in some places.
- 60–79
- Mostly template. More copied than chosen.
- 80–100
- Pure autopilot. Nothing looks chosen on purpose.
What happens to my image or website link?
For a website link, Cloudflare opens the page for us and sends back an image of it. We send the image to Claude, an AI model made by Anthropic, to produce the score. Then we store the image with its result, and for a link, the link without anything after a ? or #. Anyone with the result link can open it. Results are not listed on the site and do not appear in search engines. To have a check removed, email hello@blends.design with the result link. We delete it within 7 days.
How is the score calculated?
Claude, an AI model made by Anthropic, looks at your image for the signs in the Slop Index. It explains every sign it finds. The score is an opinion, not a fact.
What does it not check?
It does not check whether the product works, whether the code is accessible, or whether the design suits your brand and users. It only checks how deliberate the screen looks.
Can I check a whole site?
Not yet. A website link checks one page, from the top down to the first 6 screens (5,400px at desktop width). A long image is checked down to the same 6 screens. If a page is longer, the result says so. We plan to add a way to check several pages together and show the signs they share.
