Project Overview

Occhio Builder is part of my Occhio suite of AI tools for design: a Chrome extension that turns heuristic evaluations into a fast, focused workflow instead of a chore. I was frustrated by how clunky existing audit tools felt – heavy, outdated, or locked behind subscriptions – so I designed Occhio Builder as a clean, modern alternative for real-world product teams.

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.

Occhio Builder now includes a paid AI plan, evolving from a hobby project into a tool that people rely on in their day-to-day workflow. Reports can be exported to share with teams, and upcoming updates focus on tighter integrations with existing design and product stacks.

My Work

I led the product from idea to shipped Chrome extension as a solo designer–builder, covering product strategy, UX, UI, and implementation.

I designed a focused interface for running heuristic audits that keeps the reviewer in flow: fast issue capture, clear categorisation, and no unnecessary steps.

I integrated the Claude Vision API so the extension can automatically flag potential issues on the page being reviewed, merging AI suggestions with human findings in one place.

I implemented export and reporting flows so issues can be shared or archived quickly, and introduced a paid AI plan to support sustainable development of the product.

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.

Learnings

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.
