AI-Assisted TXT | MD | RTF Capture & Knowledge Management System

AI-powered note capture, structured knowledge management, and document organization system. Built with privacy-first architecture and modular extensibility for enterprise knowledge workflows.

Problem Context

Organizations needed a unified system to capture, organize, and retrieve knowledge across multiple document formats (TXT, Markdown, RTF) while maintaining privacy and supporting team collaboration.

Key challenges included:

  • Fragmented knowledge across different file formats and storage locations
  • Lack of structured organization and ownership boundaries
  • Manual document management without AI-assisted capture capabilities
  • Need for modular, installable architecture within larger platform ecosystems

System Architecture

The system follows a modular, installable-app architecture with clear ownership boundaries and metadata-driven rendering. The architecture separates document lifecycle management from presentation logic, enabling extensibility without core system changes.

Core components include:

  • Folder-based organization with hierarchical structure and ownership scoping
  • Metadata-driven rendering engine supporting multiple document formats
  • AI-assisted capture workflows integrated into document creation pipeline
  • Privacy-first data isolation ensuring user data remains secure and private
