Designers waste time recreating UI changes across Figma and live products. A browser extension or plugin could let them tweak live components directly in the product while generating clean CSS/React diffs for developers.
Target design teams at mid-size SaaS companies who already use design systems but struggle with handoff. The first version could be a Chrome extension that overlays edit controls on production sites.
The biggest risk is adoption - designers might prefer sticking to their existing Figma workflow.
