Slicer Website Audit Audit entire websites and recorded user flows in one pass, instead of reviewing page by page. Slicer automatically surfaces UI/UX patterns and issues across a whole product, saving teams hours of manual review. From any audit, extract the components behind the patterns you find and turn them directly into buildable code or prompts - so insights don't just sit in a report, they become shippable work.

Slicer Components Copy Extract any live component from any website - including its styles, interactions, animations, states, and responsive behavior - and turn it into clean React code or an AI-ready prompt. No more screenshotting or manually recreating UI from scratch. Remix components on the Canvas before exporting, so what you extract is ready to build with immediately.

Questions & Answers

As answered by people managing GNU Emacs and Slicer.dev.

What makes your product unique?

Slicer.dev's answer:

Slicer audits entire websites and recorded user flows, giving teams a structured way to evaluate UI and UX across a whole product rather than page by page. On top of that, it can extract any individual component it finds into a ready-to-use AI prompt or React code, so insights from an audit turn directly into buildable output.

Why should a person choose your product over its competitors?

Slicer.dev's answer:

Most tools only do one half of the job - either auditing a site's UX or helping you copy a component. Slicer does both: it audits full websites and recorded flows to surface UI/UX issues and patterns at scale, then lets you extract any component from that audit straight into an AI prompt or React code. That combination means audit findings don't just sit in a report - they become usable output immediately.

How would you describe the primary audience of your product?

Slicer.dev's answer:

Anyone from individuals to companies with in-house design/AI experts who need to audit their own, customers or competitors' websites and user flows, along with product designers and frontend developers who use Slicer's component extraction to act on what those audits find.

What's the story behind your product?

Slicer.dev's answer:

Slicer began around the idea that auditing websites and user flows shouldn't be a purely manual, report-based exercise. It grew into a platform that lets teams systematically review entire sites or recorded flows, with the ability to extract any specific UI component discovered along the way into an AI prompt or React code - turning audit work directly into action.

Which are the primary technologies used for building your product?

Slicer.dev's answer:

Slicer is built as a Chrome extension that inspects and audits live websites and recorded user flows, using web technologies to analyze DOM/UI structure and convert findings into structured outputs like AI prompts or React code.

Who are some of the biggest customers of your product?

Slicer.dev's answer:

Well-known Lithuanian tech businesses
