You need a landing page and your designer is unavailable. Hiring a freelancer would take a week and cost $500. Here's the honest version of how to create a landing page with AI — not the "AI is magical" version, the one that describes what actually happens.
I've run this workflow probably 40 times. Not every output is great. But the good ones come out faster than anything else I've tried, and the workflow matters as much as the prompt.
Why AI Works for This
The old way: write a brief, hand it to a designer, wait three days, give feedback, wait again. Total time: one to two weeks. Cost: $500-2,000 for a competent freelancer.
The AI version: write the brief yourself, paste it into Claude or ChatGPT, get back a working page in 90 seconds. The AI handles the HTML, the CSS, the layout, and a first draft of the copy. You iterate from there.
The output isn't perfect. The AI doesn't know your brand voice, your customers, or which specific phrases convert for your audience. What it gives you is a working starting point that takes 5 minutes to refine rather than 5 days to build from scratch.
What a Good Landing Page Actually Needs
Before writing a prompt, it helps to know what you're asking for. A functional landing page needs:
- A specific headline that names who the page is for and what they get
- A subheadline that handles the obvious objection or adds one more detail
- A single CTA — one action, not three options
- Proof or specifics — a number, a result, or a fact that builds credibility
- A footer with a way to contact you or find you
That's it. The AI will try to add testimonials, feature comparisons, and pricing tables. Keep what's useful. A simpler page with a clear CTA generally outperforms a longer page with everything on it.
The Prompt
Create a landing page for [product or service].
What it is: [one sentence]
Who it's for: [specific person — their role, their situation]
What you want them to do: [one action]
One specific result this delivers: [be concrete — "saves 2 hours/week", "cut churn by 30%"]
Tone: [direct and confident / warm and friendly / minimal / bold]
Build it as:
- Single HTML file with embedded CSS
- Hero: headline, subheadline, CTA button
- 3 benefit sections focused on user outcomes, not feature descriptions
- Social proof placeholder (I will fill this in)
- Footer with contact info
- Mobile responsive
- Output only the HTML
The "specific result" field matters most. It forces the AI to write outcome-focused copy instead of feature descriptions. "Saves 2 hours per week on reporting" beats "automated reports" every time.
The Result
What you get back is a complete .html file. Open it in a browser. Check:
- Does the headline name your audience and their outcome?
- Does the CTA button say something specific?
- Do the three benefit sections describe results, not features?
First drafts are usually 80% there. The headline is the most common thing to fix. Tell the AI: "Rewrite the headline for a [specific role] who is struggling with [specific problem]. Lead with the outcome." One follow-up message handles it.
Making It Live
You have the HTML. Now what?
Go to HTMLPub. Paste the HTML into the editor. Your page is live with a shareable URL in about 30 seconds. The free tier includes publishing — no credit card, no server setup required.
If you're running paid traffic to the page, connect a custom domain on the $10/month plan. The default subdomain URL is fine for sharing and testing.
Three Tweaks That Make It Work Harder
1. Replace the headline yourself. Write it based on what actually converts for your audience. The AI's headline is a strong draft; yours should be based on what you know about your customers.
2. Fill in the social proof section. The AI leaves a placeholder. Put your best number, result, or quote there. "Used by 4,000+ teams" or "Helped [client] cut onboarding time in half" — real specifics, not filler.
3. Fix the CTA copy. "Get Started" is weak. "Start Your Free Trial" or "Book a 15-Minute Demo" is specific. Specific CTAs convert better. Takes 10 seconds to change.
A Few Examples
SaaS trial page: I prompted Claude with a specific persona and outcome for a project management tool. First output took 90 seconds. The headline needed one rewrite. Page was live on HTMLPub in under 5 minutes.
Freelancer portfolio: Asked Claude to build a portfolio page for a UX designer with three case study sections. Output was clean, mobile-responsive, and had better copy structure than the brief I started with.
Event registration: Webinar registration page with a form embed. Three minutes total. The AI built the structure; I swapped in a Jotform embed code for the form. Done.
