Technical Approach: Architecture and Automated Workflow

Technical Architecture

  • Frontend: Next.js15 + React Server Components
  • Language: TypeScript for end-to-end type safety
  • Database: PostgreSQL (hosted on Neon) for handling metadata relationships
  • ORM: Prisma for type-safe migrations
  • AI Engine: GPT-4o for visual analysis and semantic summarization

Processing Workflow

  1. File ingestion → 2. AI asynchronous analysis → 3. Metadata storage in PostgreSQL → 4. Zero-refresh UI update The entire workflow is automated with no manual intervention.

Core Features and Application Evidence

Core Features

  • Semantic search: Directly search content (e.g., "last month's dining receipts")
  • Automatic classification: Categorize into medical/financial etc. based on content
  • Mobile-first: Shoot with phone and upload/save instantly
  • Security isolation: User data is independent

Application Evidence

  • Personal: Quickly find "2025 invoices" when filing taxes
  • Enterprise: Improve collaboration efficiency when processing contracts
  • Researchers: Build knowledge graphs for in-depth retrieval Verifies the system's effectiveness in solving real pain points.
