Prompts to build a landing page with AI
Asking an AI to "make me a landing page" gets you a landing page that looks like all the others. These prompts come with the art direction, the rhythm and the motion already decided, with their numbers, so what's left to decide is your product. Obsidiana and Cardumen are free.
4 prompts
More than "make me a landing page"
Each prompt pins down the section structure, the motion, the palette and the typography. Your AI doesn't improvise the design: it builds it.
For studios, SaaS and apps
Obsidiana is a studio site in near-absolute black; Cardumen, a SaaS with a particle school that dodges the pointer; Cumbre, an app with a phone that rotates in 3D; Fresco, a launch told room by room.
In the agent you already use
Paste the prompt into Claude, ChatGPT, Cursor or v0, or let your agent fetch it on its own through the MCP server.
What each prompt includes
- The page structure, section by section, and the motion of each one with its numbers.
- The palette by role and the typography, so you can change them to the brand knowing what you're touching.
- The copy in blocks per section, to swap for the business's own before pasting.
- Acceptance criteria to check that what your AI built is what you asked for.
How to use it
- Open the layer and copy the prompt.
- Paste it into Claude, ChatGPT, Cursor or v0, or let your agent fetch it with the MCP server.
- Swap the copy, the photos and the brand for the business's own. The docs explain how to bring it into Next.js, Astro or WordPress.
FAQ
Before you start
You can, but without clear direction the model fills the gaps with the most common choices, and the result looks like any other landing page. The prompt gives it the decisions a designer usually makes: which sections, in what order, how each one moves and with what numbers.
Every generation is different: your AI makes its own version, not a pixel copy. What the prompt pins down is the structure, the rhythm and the motion, with their numbers and acceptance criteria; what changes are the visual details, the images and the copy you put in.
Written and checked with Claude Opus 5, and the Obsidiana prompt has also been tested with ChatGPT. Any agent that accepts a long prompt can use them, but we haven't measured them against others.
With any paid plan: a commercial license for your own and your clients' projects, no attribution and no limit on sites. It doesn't allow reselling or redistributing the prompts or the code as they are.
Unlimited: $79 a year or $139 for life (one-time payment). It unlocks the whole library, not just these. Obsidiana, Cardumen, Vermell and Laocoonte are free so you can try the flow before paying.
