Prototype a Website with AI in Minutes
A good prototype answers one question quickly: does this idea feel right on a real page? With SiteSim you can type the idea, watch the page appear, and decide in minutes instead of days. Here is a practical way to work.
Start with one sentence
Open SiteSim and describe the page in a single sentence. Name the audience, the main action, and the mood. For example: "A landing page for a neighbourhood bike repair shop with a booking button, a price list and a friendly, sunny look." That gives the AI enough to choose a layout, colours and copy.
Read the result like a visitor
The preview updates live beside the code. Scroll it the way a visitor would. Ask yourself three things: what is the page about, what should I click, and does it feel trustworthy? Write down what you would change before you touch anything.
Iterate in small steps
Use the agent chat for one change at a time. Short requests keep the edits focused and easy to compare:
- "Make the hero headline larger and move the booking button above the fold."
- "Swap the colour scheme to deep green and cream."
- "Add a three column section for services with simple icons."
Each step is quick to judge. If you like it, continue. If not, ask for a variation or edit the code directly.
Edit the code when you want control
SiteSim gives you the real HTML, CSS and JavaScript in an editor. Tweak a spacing value, rename a heading, or paste in your own copy. The AI and your hands work on the same files, so you can mix both whenever it is faster.
Test on a phone sized screen
Most visitors arrive on mobile. Resize the preview to a narrow width and check that text wraps, buttons are easy to tap and images fit. Ask the AI to "make this layout work well on small screens" and review the update.
Share one link for feedback
Every sim has its own link. Send it to a teammate, a client or a friend and collect reactions while the idea is fresh. Real comments on a real page are far more useful than a description in a meeting. Browse the gallery for inspiration on what other people have shared.
Bring your own references
With a Pro plan, the AI can browse an existing site so you can say "build something with this structure for my business." You can also generate images for hero sections without leaving the editor, then export the finished project when you are ready to host it.
A simple prototyping checklist
- Write the one sentence brief.
- Generate the first version.
- List three improvements.
- Apply them one at a time.
- Check the narrow mobile view.
- Share the link and gather feedback.
Following this loop, many ideas reach a shareable state in a single sitting, and the ones that need more work show it early, when changes are cheap.
Try it now
Type your idea into SiteSim and see your first page appear. Creating is free, and Pro adds unlimited AI messages, browsing and deep export. If you want to share and tinker with small code snippets afterwards, WebFiddle is a handy companion.
