The problem is mundane but universal: adults accumulate legal and financial papers (insurance policies, tax forms, medical bills, warranties, kids' records) and dump them into folders or camera rolls where they become unfindable. Scanning tools like Genius Scan solve capture but not organization, so the pile just moves from paper to a digital mess. DocVault Organizer is a mobile app that auto-categorizes and names incoming personal documents so nothing gets lost in a folder dump. The core solution: on ingest (photo, share-sheet import, or email forward), the app classifies the document type, extracts key fields (dates, amounts, parties), and applies a consistent naming and folder scheme automatically, so the vault stays searchable without manual filing. An MVP would focus on three steps: fast capture, reliable auto-naming for a handful of common document categories (tax, insurance, medical, bills, IDs), and search. Revenue is a simple B2C subscription: a free tier limited by document count, and a paid tier (comparable utility apps here run in the five-figure monthly MRR range) unlocking unlimited storage, bulk import, and family sharing. Go-to-market starts where the pain is voiced: the HN 'family data warehouse' thread shows people actively seeking a system for tracking documents across themselves, spouses, kids, and parents. Growth loops come from family sharing (one organizer invites a household) and from tax/renewal season urgency driving seasonal installs and word of mouth.
