What It Does

Hawker Oracle scrapes live food data from Burpple, Google Maps, and Reddit across Singapore's hawker centres, then uses OpenAI to rank and recommend the best stalls based on your query, budget, and location.

No more stale 2022 reviews. No more scrolling 10 Reddit threads. Just ask the Oracle.

Features

• 🎰 Food Roulette — Feeling adventurous? Let the Oracle pick a hidden gem for you
• 🗺️ Map View — See all recommendations on an interactive map
• 📊 Cross-Source Confidence — Stalls mentioned on both Reddit AND Burpple get a higher confidence score
