JASS Windows Power Centre

A collection of lightweight, practical Windows desktop utilities built with Python + PySide6.

The JASS Windows Power Centre is designed as a growing personal toolkit for file management, document inspection, data exploration, system diagnostics, creative work, and everyday Windows productivity.

The applications are intentionally modular: each utility can be run independently and most tools require only Python and PySide6, with additional packages used only where a particular format requires them.

✨ Toolkit Highlights

Standalone Python applications
Windows-focused
Local-first and privacy-friendly
Read-only design wherever practical
Background scanning for larger operations
SQLite-based local catalogs where useful
CSV / JSON / TXT export in many tools
No cloud account required
No central server required
Lightweight dependencies
Each application can be used independently

🔒 Design Philosophy

The JASS Windows Toolkit follows a few simple principles:

Local First

Applications operate on the user's own Windows machine whenever possible.

Privacy First

There is no requirement to upload personal documents, databases, photographs or stories to a cloud service.

Lightweight

The toolkit avoids unnecessary heavyweight frameworks and dependencies.

Independent Utilities

Each application should remain useful on its own rather than requiring the entire toolkit.

Read-Only Where Practical

Inspection and cataloging applications avoid modifying the source material.

Explicit Actions

Operations that can change system state or user data use explicit controls and, where appropriate, confirmation dialogs.

Practical Over Complex

The goal is to solve real everyday problems without turning every utility into a large software platform.

🧪 Development

Applications are developed and tested incrementally.

Typical development workflow:

Define the utility's purpose
Keep dependencies minimal
Build the PySide6 interface
Implement the core operation
Add safety checks
Add export/persistence where useful
Syntax-check the Python source
Test on Windows
Freeze a stable version
Add the next independent utility

🚀 Roadmap

Possible future additions include:

More document and ebook tools
Archive Explorer
Markdown Library Manager
Subtitle Library Manager
Image Duplicate Finder
Video Metadata Explorer
Font Explorer
Windows Environment Variable Explorer
Local Application Launcher improvements
JASS Toolkit packaging
Portable toolkit distribution
Optional integration with local AI through Ollama / LM Studio

AI integration, where added, will remain optional rather than being a requirement for the basic utilities.

📜 License

Choose and add the repository's preferred license before public distribution.
