AdsWebAI, which brands itself Motion Web, lists 24 prompts split twelve free and twelve premium, and all 24 of them render in full to anybody who loads the page. The premium ones are not blurred or truncated. They are just there, with a copy button.
The site's own source declares the whole prompt set CC0, a dedication to the public domain. So the honest summary is that this is a free resource with a price tag drawn on the front of it, and the useful thing on this page is the method for spotting the next one.
What is actually there#
| Catalogue | 24 prompts, 12 listed free and 12 listed premium |
| Length | around 500 characters each, so 70 to 90 words |
| Categories | hero and landing lead, then SaaS, portfolio, app, ecommerce, web3 |
| Listed price | $19 a month |
| Licence | the prompt set is declared CC0 in the project source |
The front end is better than the catalogue behind it. There is a left sidebar, category filters, a coherent dark theme and a command palette that searches the whole set, which is a nicer way to browse 24 items than most of the libraries selling hundreds manage.
The previews are hand-built CSS animation loops rather than video, so the gallery loads instantly and costs nothing to serve. The limit is in the same breath: the loops are drawn from a small set of shared styles and reused across items, so a preview shows you a mood rather than the page you will get.
One practical note before you go looking. The domain and the brand printed on the page are two different names, so searching for either will not surface the other, and neither will lead you to much written about the site anywhere else.
The catch#
The $19 a month plan has no way to pay it. There is no processor behind the button, no external storefront, and no field anywhere on the site that accepts a card. The maximum anybody can spend there is nothing, which is also the correct price given that every prompt is already readable.
That combination is not rare in this category, and it is the reason to read this page even if you never visit that site. Three checks, three minutes, and they work anywhere:
- Click the upgrade button before you fill in anything. If it opens no checkout, there is no product behind it.
- Open a premium item while logged out. If the text is already in the page, you are being asked to pay for a copy button.
- Read the licence. A prompt dedicated to the public domain cannot also be the thing you are buying a commercial licence for. The same question, asked of a catalogue that repackages free components, gets the same answer.
None of that is an accusation about anyone. It is a description of what a storefront looks like when the shop was built in a day and never opened, and it is worth being able to recognise on sight.
What 24 paragraphs buy you#
Length is not quality, and a short prompt is not automatically a bad one. But it is worth knowing what you are holding.
An AdsWebAI prompt is about 500 characters, and it divides like this:
- Roughly 25 words are a shared stack instruction repeated on all 24, naming React, TypeScript, Tailwind and Framer Motion, ruling out external UI kits and asking for
prefers-reduced-motionto be respected. - That leaves about fifty words specific to the design being described.
- Eleven of the 24 carry an unfilled
{product}or{brand}token the site never substitutes, so fill those in before you paste.
Fifty words is a paragraph. A paragraph can carry a concept and a mood, and it cannot carry a palette, a type scale, a rhythm and a motion system, so the model supplies those instead. It supplies them the same way every time, which is the mechanism behind every page that looks like every other page built that week.
What a short prompt is good for#
Fifty words is not useless. It is the wrong tool for one job and a good tool for another, and knowing which is which will save you an argument with a model.
- Good: a section brief, once the page already has a palette, a type scale and a rhythm. The prompt names the effect and the existing system constrains everything else.
- Good: a structure to react against, when what you want is something to rewrite rather than something to keep.
- Poor: the first instruction on an empty project, where nothing constrains the model and it reaches for its defaults on every axis at once.
Order matters more than length. Paste a full specification first and a short prompt afterwards for one band of the page, and the short prompt inherits every decision above it. Paste the short prompt into an empty project and it invents them.
What a prompt has to decide#
The question worth asking of any library, at any price, is how much of the design is settled in the file before the model gets a say.
Thanor writes every prompt to the same fixed shape:
- Four to six hex values, each with a named role, and the neutral's hue bias stated, because a pure mid-grey is the clearest tell of a generated design.
- Two named faces with the fallback stack written out, a scale in px, the weight at each size, line heights and letter-spacing.
- A grid, a gutter, page margins and a vertical rhythm as real numbers, in the shape of
160 / 96 / 48. - Named curves with real values such as
cubic-bezier(.16,1,.3,1), durations in ms, and which moves run off scroll progress rather than firing once. - Numbered sections, each buildable without having read the one before it.
- A never list written against that design, naming the defaults it must avoid.
- Acceptance checks a person can run by eye.
Every file clears a 1,200 word floor before it enters the library, and an automatic gate rejects it for a missing block, fewer than four colours, or motion described with no curve and no duration.
If you are choosing today#
| If you want | Take |
|---|---|
| Two dozen short prompts at no cost | AdsWebAI, all of them readable now |
| A fast way to browse a small catalogue | AdsWebAI, the command palette is good |
| Depth inside a single file | Thanor |
| The design decisions themselves, as exact values | Thanor |
Take the free ones. They cost nothing, the licence is unambiguous, and a paragraph is a perfectly good starting point when you already know what the page should look like.
When you do not, no number of paragraphs will tell you, and that is the whole difference between a prompt and a specification.
Go and look at Thanor, and see how much of a design can be settled before anybody opens a builder.
Questions this raises
Is AdsWebAI free to use?
In practice yes. All 24 prompts, the premium ones included, render in full to a logged-out visitor with a working copy button, and the project's own source declares the prompt set CC0, which is a dedication to the public domain.
Why is AdsWebAI also called Motion Web?
The domain and the brand on the page are different names for the same site. Searching for either one will not surface the other, which is worth knowing if you are trying to find it again.
How long is an AdsWebAI prompt?
Roughly 500 characters, which is 70 to 90 words. About 25 of those words are a shared stack instruction repeated on all 24, so the part unique to any one prompt is around 50 words.
How do I tell whether a prompt library is maintained?
Click the upgrade button before you enter a card, open a premium item while logged out and see whether the text is already on the page, and read the licence. Three minutes, and they answer more than the marketing copy does.
What makes a website prompt reproducible?
Named values. Hex codes with a role each, a type scale in px, a vertical rhythm in real numbers, an easing curve with its cubic-bezier written out and a duration in ms. A prompt that names none of those gets a different page every time it runs.
