Proof Finder: AI File Finder

Proof Finder is a secure document vault and AI file finder that helps you store, organize, and instantly find any receipt, bill, warranty card, invoice, prescription, ID, or recording — in seconds. No more digging through messy folders, buried emails, or thousands of gallery photos. Your private, searchable, paperless filing cabinet for every important document you own.

🛡️ SECURE VAULT — LOCAL-FIRST & ENCRYPTED

A privacy-first document organizer, file locker, and vault — we never see, collect, or store your files or keys on our servers.

• On-device encryption secures every file directly on your phone — no cloud upload required
• Your 12-character master key is the only way to unlock your encrypted vault — store it somewhere safe
• Password-protected biometric app lock (Fingerprint / Face ID) adds a second layer of protection
• True secure offline storage and file locker: documents, receipts, IDs stay under your control

🧠 AI SEMANTIC SEARCH — FINDS FILES BY MEANING

Most file managers search exact filenames. Proof Finder's AI understands meaning.

• Combines fast keyword search (BM25) with a local, on-device AI model (MiniLM ONNX) for smarter results
• Search naturally — try "Toyota brake pads invoice" or "doctor bill for knee surgery" — no exact filename needed
• 100% offline AI processing — no internet required, nothing ever leaves your phone
• When exact keywords come up empty, semantic AI scoring kicks in — smart search always finds something relevant

☁️ ENCRYPTED GOOGLE DRIVE BACKUP

Bring your own cloud instead of trusting a third-party server.

• Connect your Google Drive — Proof Finder creates a private folder to sync your fully encrypted vault
• Lost your phone? Install on a new device, enter your master key, and restore your entire archive in minutes
