The four exact prompts I gave Claude Fable 5 and Claude Opus 4.8
in the build video — a landing page, a pitch deck, an animated site, and a mobile booking flow.
Copy them free and run the same head-to-head yourself.
Same prompt, two models, side by side. That is the whole test.
STEP 1
Copy a prompt
Pick one of the four below and press Copy. They are reproduced word for word from the video.
STEP 2
Paste it into your builder
Drop it into Claude, Lovable, v0 or any model you want to test. For a real comparison, run the same prompt in two.
STEP 3
Compare the results
Judge each output against the brief — pricing tiers, edge cases, motion — and keep the one that actually fits.

The four prompts
Each one stresses a different skill — layout, data storytelling, motion, and a full multi-screen flow.
01Tempo — landing pageMarketing site
Pricing tiers with monthly / annual billing, three testimonials of deliberately uneven length, an FAQ and a signup form — responsive on desktop and mobile.
Design a marketing landing page for Tempo, a time tracking app for creative teams — designers, video editors, copywriters. Include: a hero section, a product overview, pricing with monthly and annual billing (Free / Studio $12 per user / Agency $29 per user), testimonials from three customers, an FAQ, and a signup form. One testimonial is only four words long, another is three sentences. The audience is creative leads who hate corporate tools. Works on desktop and mobile.
02Ferrow — pitch deck10-slide deck
Real startup metrics turned into visuals instead of bullet lists — a full seed narrative meant to be skimmed in two minutes.
Create a 10-slide seed pitch deck for Ferrow, a marketplace connecting independent coffee roasters with cafes. Cover: problem, solution, how the product works, market size (European coffee wholesale is roughly 9B EUR), traction (GMV grew from 40K to 310K EUR in 12 months; 85 roasters, 640 cafes), business model (8% take rate), competition, unit economics (CAC 120 EUR, LTV 2,900 EUR, payback 4 months), the team of three, and the ask: 1.5M EUR. Turn the numbers into visuals, not bullet lists. Investors will skim this in two minutes.
03Halftone — animated siteMotion-first
Motion as the medium, not effects layered on top: a fixed dark brand palette, a supplied seven-image kit, and two moments of surprise.
Design the website for Halftone, a three-person design studio working mostly with music labels and cultural institutions. Motion is the studio's signature, so the site itself must feel like a piece of motion design, not a static page with effects on top. Every section should move with intention: how elements enter, how they react to the visitor, how one section hands over to the next. The opening screen should already be in motion before any scrolling happens. Surprise me at least twice.
Sections: intro, six selected projects, how the studio works, the team, contact.
Brand kit attached: one hero visual and six project covers. Use them as the visual core of the site. Palette: background #0A0A0F, surface #14141C, text #F2F0EA, secondary text #8A8A96, primary accent #D9FF3D, secondary accent #FF3DA6. Typography and all other design decisions are yours. It should not look like a template.
Image prompts for the brand kit
The Halftone brief expects one hero visual and six covers. These are the exact generation prompts used to make them — start with the master block, then append one line per image.
MAbstract cinematic brand artwork for a motion design studio. Epic scale and depth, gallery-poster quality. A blend of long-exposure light photography and refined 3D render. Near-black background (#0A0A0F). The only strong colors are acid green (#D9FF3D) and magenta (#FF3DA6) rendered as light, with warm off-white highlights. Fine film grain, high contrast. No text, no letters, no logos, no people, no faces, no recognizable brands.
1HERO (16:9, landscape): A vast dark space crossed by one sweeping ribbon of acid-green light, faint magenta reflections on a barely visible floor. Feels like the opening frame of a film title sequence.
2COVER, record label (4:5, portrait): A black vinyl record mid-spin in darkness, its edge catching acid-green light, subtle motion blur.
3COVER, concert hall (4:5): Long-exposure light trails shaped like sound waves flowing through a dark concert hall, green fading into magenta.
4COVER, museum (4:5): A monolithic dark sculptural form lit only by a thin magenta edge light, deep museum darkness around it.
5COVER, festival (4:5): Volumetric stage light beams cutting through haze over an empty night field, green and magenta, no people.
6COVER, album campaign (4:5): Liquid chrome form frozen mid-splash, reflecting acid green and magenta, floating in black.
7COVER, digital gallery (4:5): A glowing green wireframe ring half-submerged in still black liquid, magenta glow beneath the surface.
04Ferry — mobile flowFull booking flow
Every screen of a real booking flow, including the hard edge cases: sold-out sailings, weather cancellations, and one wheelchair space per sailing.
Design the full mobile booking flow for a small ferry company: choose one of three routes, pick a date, add passengers (adults, children, bicycles — and there is one wheelchair space per sailing), pick a seat class, review, pay, get confirmation. Sailings can sell out, and departures are sometimes cancelled because of weather. Design every screen of the flow.

Questions
What tools do these prompts run in?
Anything that turns a prompt into a design or an app — Claude (Claude Design / Artifacts), Lovable, v0, and similar. In the video each prompt was run through Claude Fable 5 and Claude Opus 4.8 and the results compared side by side.
Which model is better, Fable or Opus?
It depends on the prompt — which is exactly what the video is about, and why the prompts are here for you to run yourself. Rather than take one verdict, paste them into both models and judge the outputs against your own taste.
Can I use these prompts for my own projects?
Yes. They are free to copy, adapt, and use commercially. The brand names, prices and numbers inside them are fictional placeholders — swap in your own.
Why are the prompts so specific?
Specific constraints — exact prices, a four-word testimonial, one wheelchair space per sailing, “surprise me twice” — are what actually separate models. Vague prompts produce vague, look-alike output; edge cases expose how each model handles detail.
Do I need images for the Halftone prompt?
The Halftone brief references a brand kit of one hero visual and six covers. The exact image-generation prompts used to create that kit are included right under the main prompt — generate your own set, or supply your own images.
