The concept is straightforward: every day at 3:00 AM, an automated workflow triggers in n8n. It uses Apify to scrape daily prices and promotional flyers from major retailers like Othaim, Panda, Sary, Amazon, and Noon. It then passes this raw, messy data through GPT-4o-mini to clean and standardize it (since every store formats its data differently), and finally saves it into Supabase, ready for the WhatsApp assistant to query in real-time.
