SKINT LABS

Change

AI-powered tools for the next generation of e-commerce.

WHAT WE BUILD

Two products. One mission. Making AI accessible, secure, and useful for businesses of every size.

AI Customer Service

JERRY

The Customer Service Bot for Shopify. Jerry connects to your store's data to answer customer questions 24/7 with real, accurate information.

  • Semantic product search in natural language
  • Real-time order tracking via Shopify API
  • Automated returns and refunds handling
  • Voice chat in 50+ languages
  • Revenue attribution and analytics
LLM Security

WONDERWALL AI

An AI firewall SDK and hosted API that protects LLM-powered applications from prompt injection, data exfiltration, and off-topic abuse.

  • 4-layer protection pipeline
  • Under 2ms local scan latency
  • Canary token leak detection
  • MIT open-source SDK on PyPI
  • Hosted API for zero-config setup

BUILT FROM SCRATCH

Skint is Australian slang for broke. Six months ago, the founder of Skint Labs didn't know how to write a line of code. No funding. No team. No technical background. Just a simple observation: small Shopify store owners were spending hours every day answering the same customer questions that already had answers in their data.

That observation became Jerry. Then, when real users started trying to jailbreak the AI, the security module built to protect Jerry became its own product: WonderwallAi. Two commercial AI products, built from scratch by a self-taught solo founder turning 40 into a fresh start.

AI tools were the equaliser that made it possible. But there's a ceiling to vibe coding. The tools got the work started. Understanding is what got it finished.

"Skint is a reminder of where this started and a commitment to building tools that are accessible — not just for companies with enterprise budgets."
