Overview
The extension helps designers, QA, and indie devs quickly evaluate live interfaces using standardised heuristics, combining manually flagged issues with AI-detected problems in a single, structured view. It uses the Claude Vision API to scan the current page, surface potential UX issues, and sit alongside human judgment instead of trying to replace it.
Outcome
Occhio Builder is now a tool I use on every UX audit, and at least a handful of other designers use it on a semi-regular basis in their own workflows. It reduces the overhead of running heuristic evaluations, surfaces higher quality issues by pairing human judgment with AI assistance, and makes it faster to produce clean, shareable reports.
Positioning it as part of the broader Occhio suite has clarified its role: Occhio Builder focuses on structured audits, while future tools in the suite support continuous, AI-assisted design review.
What I learned
Building and evolving Occhio Builder reminded me why I enjoy working at the intersection of design, product, and engineering. Treating it as a serious, paid product rather than a weekend experiment pushed me to think more deeply about reliability, pricing, and how AI can support designers without getting in their way.
Shipping the Claude Vision-powered flow reinforced a core principle for me: the best AI tools amplify expert judgment instead of replacing it. That mindset now shapes how I approach future Occhio tools and other products I design.
