- Show HN: I built a free app for New Yorkers to save money on groceries
A free app for New Yorkers to save money on groceries by automating savings through card cashback, weekly coupons, and CPG rebates. The app, powered by an AI tool using a trained LLama model, is NYC-only with coverage of ~690 stores and offers no-login access. The creator seeks feedback on prioritizing data coverage or freshness when working with messy, multi-source retail data.
