The short version
Designers have a specific problem with most AI builders: the output looks AI-generated. Generic gradients, identical layouts, Inter on Inter on Inter, the same hero pattern with a laptop mockup. The designer can spot a templated site in 2 seconds — and so can the designer's clients and peers.
Website Killer is built around 52 distinct design systems (Linear Clean, Stripe Flow, Raycast Glass, Editorial Magazine, Swiss Grid, Neo-Brutalist Light, Anthropic Warm, Brutalist Dev, Cinematic Showcase, Agency Portfolio Dark, etc.). Each has its own typography pairing, surface treatment, motion vocabulary, and design references. The AI picks per the prompt; the designer chat-edits from there.
What this is for designers: a 90% finished site in 10 minutes, then 30 minutes of taste-editing. What it isn't: a Figma replacement. The polish-the-last-10% workflow stays in your tools — export the code if you want to drop tokens, run motion experiments, or hand off to a build team.
The job to be done
I can spec a great site in my head — I just don't want to spend a week translating it into builder blocks. Get me to 90% in 10 minutes; I'll polish from there.
Why other AI builders fall short for this job
- A visual canvas takes the full week even when you know what you want
- Per-site pricing on canvas tools adds up fast
- Component-only AI tools give you parts, but typography and rhythm are inconsistent
- Most AI tools output design that screams 'AI-generated'
- Template-builder defaults aged out of taste five years ago
What Website Killer ships for designers
- A design system tuned by designers — not a generic Bootstrap clone
- 52 distinct design systems with their own typography, surface, and motion vocabularies
- Real motion primitives baked into templates for hover, scroll, and section transitions
- Source-code export so you can hand off a clean repo to your dev team
- Live chat-editing on the rendered site, not in a code editor
- Per-month pricing instead of per-site
- Bold typography pairings (not Inter)
Where this fits
Real-world scenarios
Personal portfolio refresh
Your portfolio is dated 2022. You've procrastinated for 18 months because it's a week of work. Generate the new version in 20 minutes, taste-edit for an hour, swap your project images, ship.
Pitch a client
You're pitching a series-B SaaS on a marketing-site rebuild. Instead of mocking up Figma frames, generate a credible v1 from the brief during the discovery call. Walk away with a deal closed and a head start on delivery.
Side-project landing
You're shipping a side project (Chrome extension, indie tool, weekend app). The landing page used to take a weekend; now it takes 30 minutes and looks like a brand designer made it.
Hand-off-ready deliverable for the client
Client wants a final deliverable they can host themselves. Export clean Next.js source code, hand it off, walk away. The client deploys to Vercel, you invoice for the work, no ongoing infrastructure dependency.
Worked examples
Prompts that work
Three prompts you can adapt for your work. The more concrete the prompt, the less editing afterward.
Editorial portfolio
Portfolio site for a senior product designer (7 yrs, currently at a fintech series-B, looking for staff role). Style: editorial magazine, restrained, lots of whitespace, big type. Four case studies with metrics: banking app redesign (24% conversion lift), billing flow rebuild (40% support ticket cut), design-system overhaul (8 designers + 30 engineers), open-source plant-care app. About: skills, location (Brooklyn). CTA: Cal.com 30-min call.
Why this works · Designer portfolio prompts should specify the design system (editorial-magazine). The AI biases template + typography accordingly.
Agency-grade marketing site
Marketing site for Field Studio, a 4-person product design agency in Portland. Style: swiss grid, bold type, restrained color (off-black + ember accent). Hero: 'We build the marketing site engineering hates building.' 5 case studies. Pricing bands. Team. CTA: book a 30-min project call.
Why this works · Agency prompts can specify swiss-grid or brutalist-dev for restrained, type-driven layouts. The AI uses the named design system as a template hint.
Brand-led DTC site
Site for Lumi, a smart lamp ($249). Style: cinematic showcase, image-dominant hero, product-photography-led. Three feature blocks. Email capture for restock. Buy CTA routes to Shopify Buy Button. Reviews with photos. Mobile-first.
Why this works · DTC brand prompts should specify cinematic-showcase. The AI biases toward full-bleed imagery and suppresses chrome.

FAQ
Frequently asked questions
Can I bring my own design system?
Right now Website Killer applies one of its 52 tuned design systems per project, picked from your prompt. Override colors, typography, and spacing via chat-edit. For strict per-client brand systems, export the code and drop your tokens in — the export is clean enough for that.
Is the output as polished as a hand-built site?
For 90% of marketing sites, yes — and it's the 90% you don't want to spend a week on. The remaining 10% is what you polish in the hand-off (custom motion, micro-interactions, brand-specific illustrations). Export the code, polish in your tools.
Can I use specific typefaces (Söhne, Tiempos, GT America)?
Google Fonts pairings are baked into the 52 design systems. For licensed typefaces (Söhne, Tiempos, GT America), export the code and swap @font-face declarations — typography customization is a 10-minute change in the export.
Does the site include built-in motion primitives?
Yes — animation primitives are baked in for hover, scroll, and section-transition animations. The AI applies motion conservatively by default (designer sites overdo motion, that's the trap). Chat-edit to dial up if your brief calls for it.
Can each project use a different design system?
Yes — each project picks one of 52 design systems per the prompt. A portfolio can be editorial-magazine; a client agency site can be swiss-grid; a DTC brand can be cinematic-showcase. The AI re-picks per-project.
What about exporting clean code for a developer hand-off?
Export ships as a clean Next.js + Tailwind project. No proprietary build system, no opinionated state management — just Next.js app router, server components where appropriate, Tailwind classes, shadcn-style primitives. A senior developer can read and modify it in an hour.
