1. Room-by-room organization where users photograph and catalog belongings.
2. AI photo analysis that suggests item name, category, and estimated value range from a single photo.
3. Receipt and warranty photo upload with AI extraction of purchase price, date, store, and warranty expiration.
4. Serial number and model capture for electronics and appliances.
5. A searchable catalog with filters by room, category, and value.
6. Estimated total home value with a per-room and per-category breakdown.
7. An insurance-ready report: a formatted PDF with photos, values, and serial numbers an adjuster can use after a claim.
8. Warranty expiration reminders and a renewal calendar.
9. Cloud backup with export to CSV or PDF so users are never locked in.
10. Privacy-first storage: items stay private to the account, with optional PIN lock for app access.
