Losing receipts and missing warranty windows on stuff you bought
“My headphones died 13 months in — 1-year warranty, and I couldn't find the receipt anyway. This happens to me constantly with appliances and electronics.”— Hacker News ↗
Receipt apps (Expensify, Smart Receipts) are built for expense reports and taxes, not warranty lifecycles — and warranty startups keep launching on HN because none has stuck. The 'snap receipt → know when the warranty expires → get warned first' loop is a distinct, underserved job.
Anyone who buys electronics/appliances
Build a warranty + receipt vault in Next.js. User snaps a receipt photo; a vision model extracts item, price, store, purchase date. User sets a warranty length; the app computes the expiry and shows items sorted by 'warranty ending soonest' with a warning badge. First 3 steps: (1) receipt upload + vision extraction to structured fields, (2) item store with computed warranty-expiry date, (3) dashboard sorted by expiry + a daily cron that flags items expiring within 30 days.
