From screenshot to code without a spec document
Paste a screenshot, a Figma export, or even a rough sketch into Onevium and describe what you want built. The agent generates the component code, applies your project's design system, and can open the result in your browser for immediate visual verification.
This is not a one-shot generator that hands you a blob of HTML. It is an iterative loop: you see the result, say 'make the spacing tighter' or 'swap the icon', and the agent updates the code and refreshes the preview.
Visual checks close the feedback loop
The hardest part of front-end development is not writing the code — it is knowing whether the code produces the right pixels. Onevium's browser integration lets the agent take screenshots of the rendered output and compare them against the original reference.
- The agent captures the current state of the component in the browser.
- It compares layout, spacing, and color against the reference image you provided.
- Discrepancies are flagged and fixed in the same session — no manual QA step.
Responsive by default
Use the resize tool to switch the browser viewport between mobile, tablet, and desktop breakpoints. The agent checks each size, flags layout issues, and adjusts the CSS until the component works across all three. You end up with responsive code that was actually tested, not just written with responsive intent.
