Screenshot-to-code tools have a fundamental problem: they only see one moment. Interfaces exist in time. Here's why that gap matters.
A screenshot captures a user interface at a single point in time. It's a frozen moment— useful for documentation, but fundamentally incomplete for reconstruction.
A screenshot shows what an interface looks like.
It does not show how it works.
When an AI analyzes a screenshot, it sees shapes, colors, and text. It does not see:
Consider a dashboard with a sidebar. A screenshot shows:
The screenshot tool will generate a static page. The video tool will generate a working multi-page app.
| UI Element | Screenshot captures | Video captures |
|---|---|---|
| Navigation | List of links | Full routing + page transitions |
| Buttons | Visual appearance | Hover + click + response |
| Forms | Input fields | Validation + error states |
| Modals | May not appear at all | Trigger + animation + content |
| Dropdowns | Closed state only | Open state + options + selection |
| Tabs | One tab visible | All tabs + content switching |
When AI tools only have a screenshot, they have to guess what happens next. Sometimes they guess correctly. Often they don't.
When you record a video of the interface working, you create an unambiguous record of actual behavior. The AI doesn't need to guess—it watches.
What you show is what you get.
If you navigate to three pages, you get three pages. If you only show one, you only get one. No hallucinations, no guessing.
This is the principle behind behavior-driven UI reconstruction— treating observed behavior as the specification, not static images or written descriptions.
Stop guessing. Start recording. Replay rebuilds what you actually show.
