Code Riff
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. no scripts. no safety net.
we talk through our prompts, we show you the mess, and we explain everything along the way. sometimes it works beautifully. sometimes it breaks. either way, you'll know enough to try it yourself.
messy real-world problems, solved with AI - so you can too.

Code Riff
Using Claude Cowork To Streamline Wet Market Operations (Live)
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
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.
