- User provides a business name/idea and wants a deployable web page
- User sends an HTML template and wants it adapted with new content/branding
- User asks for a "one-pager" or "single-page site"
DON'T USE WHEN:
- User wants a multi-page website (use a web framework instead)
- User wants an email template or newsletter (different format/constraints)
- User wants a blog, documentation site, or wiki
- User wants to edit an existing live site (this builds new pages, not patches)
- User wants a web app with backend logic, auth, or databases
OUTPUTS: Single self-contained .html file (no external dependencies except Google Fonts). Ready to open in browser, deploy to any static host, or deliver to a client.
INPUTS: Business name, what it does, target audience, desired tone. Optionally: a reference HTML template to adapt.

Landing Page Builder
Generate polished, conversion-optimized landing pages from natural language descriptions.
Workflow
If user provides a reference HTML template:
- Read the provided template
- Identify all text content, branding, and copy
- Modify the existing template — do NOT rewrite from scratch
- Replace copy, brand name, colors, and content to match the user's brief
- Preserve ALL CSS, animations, layout structure, SVG filters, and JavaScript exactly
- Output the adapted
.html file
If no template provided:
- Ask the user (if not provided): product/service name, what it does, target audience, desired tone
- Read the base template at
assets/template.html
- Replace all
{{PLACEHOLDER}} tokens with content tailored to the user's request
- Customize colors, copy, sections — add or remove sections as needed
- Output a single self-contained
.html file

Design Principles
- Mobile-first responsive design
- Clean typography with Inter font
- Subtle shadows, rounded corners, generous whitespace
- Conversion-focused: clear hierarchy, single primary CTA repeated
- Fast: no JS frameworks, no external dependencies beyond Google Fonts
- Accessible: semantic HTML, good contrast ratios
Common Mistakes to Avoid
- Don't rewrite templates from scratch — when adapting a reference, modify in place. Rewriting loses the design quality.
- Don't use generic stock copy — every line should feel specific to the business, not "lorem ipsum with nouns swapped in"
- Don't add sections the user didn't ask for — less is more. A tight 3-section page beats a bloated 8-section page.
- Don't break responsive behavior — test mentally that your changes work at mobile widths
Customization
Feel free to:
- Add/remove entire sections (not all pages need pricing or testimonials)
- Change the grid layouts, add animations with CSS
- Swap the font via the Google Fonts link
- Add custom CSS variables for additional theming
- Embed forms, videos, or other interactive elements as needed
Output
Save the final HTML file to the user's workspace or specified path. Suggest deployment options:
- Quick: Open locally or share the file
- Free hosting: GitHub Pages, Netlify, Vercel, Cloudflare Pages
- Custom domain: Pair with any of the above
