Build my landing page — but I could not preview it

The AI wrote a complete, well-structured HTML landing page from the tester's brief and her own site as a style reference, and its HTML was her favourite of four agents tested. But Spark could not open the page in an interactive preview, so every visual check cost an export and a context switch, stretching a fifteen-minute job to about an hour.

This only partly worked. Read what happened before you try it.

How it works

  1. Provide one-sentence goal, section list and own website URL as style reference
  2. Agent presents plan
  3. User approves
  4. Agent writes complete HTML file
  5. User exports and opens it separately to check the design
  6. Describe each change back in words

Why it’s worth knowing

The code was the best of four agents, yet the missing preview loop quadrupled the time the job took.
