Chuyi quit her corporate job to help manage a wet market vegetable store at Marine Terrace. She tracks competitor prices and supplier orders through WhatsApp and spreadsheets — all by hand.

So we used Claude Cowork to build her a competitor pricing guide and supplier management dashboard in one hour, having fun while doing it together.

What you'll hear in this episode:
- A wet market store operator walking through her daily pricing and supplier workflow
- Using Claude Cowork to scrape and compare prices across FairPrice, Sheng Siong, Cold Storage, and more
- Building a supplier management tracker with price logging, margin calculations, and trend analysis
- AI "hallucinating" wet market prices — and Yaohong catching it live
- Honest conversation about scraping ethics, data accuracy, and why "your data will never be clean"
- Why not everything needs code — sometimes a spreadsheet is the real unlock

Hosts: Eric Tan (non-technical builder) & Yaohong Ch'ng (engineer, Superuser HQ, ex-Stashaway head of Data)
Guest: Chuyi (Le Fresco, 50 Marine Terrace)

LEARN ALONG — Glossary:
- Claude Cowork: A browser-based AI assistant from Anthropic that can control your files and browse the web. Costs ~$30 SGD/month on the Pro plan.
- Scraping: Automatically collecting data from websites using a bot instead of copying it by hand. Some websites block this.
- Tokens: The units AI models use to process text. More tokens = more cost. Like minutes on a phone plan.
- Hallucination: When AI confidently makes up information that isn't real. In this episode, it estimated wet market prices at "20-40% cheaper than supermarkets" — a guess, not data.
- MCP (Model Context Protocol): A way for AI agents to connect to external tools like Notion or Google Sheets. Think of it as a universal adapter plug for AI.
- Network egress: A security setting that controls which websites an AI tool can access from your computer. Like a bouncer checking IDs.

ABOUT:
Code Riff — messy real-world problems, solved with AI, so you can too.

One of us can't code. The other's been coding since he was 13. Every episode, someone brings us a real problem and we try to solve it with AI in one hour live.
