Dataset Tools: An AI Metadata Viewer

Dataset Tools is a desktop application for browsing and managing AI image datasets with comprehensive metadata extraction. Whether you're organizing generations from A1111, ComfyUI, Civitai, or other tools - or just curious what parameters were used to create that cool image - Dataset Tools has you covered.

Built with Python and PyQt6, it provides an intuitive interface for viewing embedded generation parameters, ComfyUI workflows, model metadata, and even camera EXIF data from non-AI images.

Future Forward We're looking into re-developing the front end with Electron, if you have concerns, suggestions or anything feel free to join our discord, pull an issue or use the github discussions. We'll always provide bug catching and error support for any PYQT6 branches. We validate that users don't always like stark changes, and we want to make the future transition as smooth as possible.

Community-Driven Development: This project is inspired by stable-diffusion-prompt-reader and thrives on community contributions. Found a bug? Have a workflow that won't parse? Want to add support for a new tool? We welcome forks, fixes, and pull requests! This is a community tool built by the community, for the community.

Features

Lightweight & Fast: Designed for quick loading and efficient metadata display with intelligent caching.
Cross-Platform: Built with Python and PyQt6 (compatible with Windows, macOS, Linux).
Flexible View Modes:
- Thumbnail Grid View: Browse images visually with thumbnail previews.
- File Tree View: Navigate folders hierarchically with expandable tree structure.
- Resizable Windows: Adjust window size to your preference - all layouts adapt dynamically.
Comprehensive Metadata Viewing:
- Clearly displays prompt information (positive, negative, SDXL-specific).
- Shows detailed generation parameters from various AI tools.
- Metadata Editing: Modify and save image metadata directly in the application.
- Non-AI Images: View EXIF/XMP data from cameras and software (privacy note: we don't extract GPS coordinates - no one needs to know about your Bluetooth spam on macOS 😄).
Intuitive File Handling:
- Drag and Drop: Easily load single image files or entire folders. Dropped files are auto-selected.
- Folder browsing and file list navigation.
Image Preview: Clear, rescalable preview for selected images.
Copy Metadata: One-click copy of parsed metadata to the clipboard.

- Bulletproof Unicode Handling: Eliminates mojibake issues with comprehensive fallback chains and robust encoding detection.
- Intelligent Caching: Smart metadata caching reduces redundant parsing for faster browsing.
- Intelligent Fallback System: When specialized parsers can't handle a file, the system gracefully falls back to vendored parsers ensuring maximum compatibility.
- 25+ Specialized Parsers: Dedicated parsers for various AI tools and platforms with ongoing expansion.
- Model File Support: Enhanced metadata viewing capabilities (Safetensors and GGUF support in progress!).
Configurable Logging: Control application log verbosity for debugging (see Debug Mode).

Known Issues

UI Limitations (v0.x)

PyQt6 Layout Issues: The current PyQt6 UI has known limitations with viewport resizing and button centering across different screen resolutions. While functional, some layout elements may appear inconsistent when resizing windows or using non-standard display configurations (4K, 5K Retina, etc.).
Material Theme Compatibility: The integrated qt-material themes, while visually appealing, are not 100% compatible with all PyQt6/Qt6 elements. Some minor visual inconsistencies may be present.
Future UI Direction: We are actively exploring a migration to Electron for v1.0 to address these UI limitations and provide better theming flexibility, improved cross-platform consistency, and easier headless/CLI integration. The Python parser core will remain unchanged - only the UI layer would be rewritten. This is under consideration - if you have concerns about Chromium/Electron (privacy, resource usage, etc.) or alternative suggestions, please join the discussion in Issues or Discord.

Parser Status

Advanced Parsers: Advanced parsing is about 75% of the way there. We're continuously working to iron out edge cases and improve extraction accuracy. Currently we are struggling to get a lot of the T5 style models to parse in ComfyUI. If you or someone you know use ComfyUI and can pass any information about workflows, or what nodes you're currently using that'd be amazing.
Draw Things: The XMP Extractor MIGHT be working, but with limited data on DrawThings and the original vendored code not working at the moment we're unsure of how this is working.

Note: This is active development software (v0.x). We're still ironing out bugs and refining functionality. Expect rough edges, but the core parsing is solid!

Supported Formats

Dataset-Tools aims to read metadata from a wide array of sources. Current capabilities include:

AI Image Metadata:

AI Image Generation Tools:
- Automatic1111 WebUI / Forge: PNG (parameters chunk), JPEG/WEBP (UserComment EXIF).

  - Standard workflows (PNG "prompt"/"workflow" chunks)
  - FLUX workflows (UNETLoader, ModelSamplingFlux, FluxGuidance)
  - SD3, SDXL, SD1.5 workflows
  - Efficiency Nodes (Efficient Loader, KSampler Efficient)

  - QuadMoon custom nodes (Thank you to Joel Traugdor for breaking the app, AND for supervising the code!)
  - HiDream workflows
  - ComfyRoll ecosystem
  - Griptape workflows
  - PixArt/T5-based models
  - AuraFlow, Lumina, Kolors
  - Advanced samplers (SamplerCustomAdvanced, BasicGuider)
  - Text combiners and prompt manipulation nodes
  - And many more custom node ecosystems!
- CivitAI Images:

Non-AI Images:

Camera/Photo Metadata: EXIF, IPTC, XMP data from cameras and photo editing software
Privacy Note: We deliberately don't extract GPS coordinates - your location data stays private! (This is also because on MacOS Pyqt6 requires bluetooth)

Model File Metadata (Header Information):

.safetensors - Lora (And related types) Only
.gguf (unknown)

Other File Types:

.txt: Displays content.
.json: Displays content.

Note: Non-image files may not display thumbnails in grid view yet - we're adding SVG icons for better file type visualization!

Dependencies

Dataset-Tools relies on several excellent open-source libraries:

Core Dependencies:

PyQt6 - GUI framework (cross-platform desktop interface)
Pillow (PIL) - Image processing and metadata extraction
pyexiv2 - Advanced EXIF/IPTC/XMP metadata reading (enhanced with pypng integration)
pypng - PNG chunk reading for large ComfyUI workflows
piexif - Additional EXIF manipulation
pydantic - Data validation and settings management
rich - Beautiful terminal output and logging system.
toml - Configuration file parsing
requests - HTTP requests for Civitai API integration
cryptography - Fernet encryption for CivitaiAPI keys.
NumPy - Workflow enhanced NumPy system.
defusedxml Secure metadata extraction.
jsonpath-ng Json Path Enabled ComfyUI Workflow support.

All dependencies are automatically installed via pip.

Installation

Installation is easy and is cross platform, there are no executables as those can create issues down the track when the developer isn't sure how that works. At the moment while we're still under heavy development the idea of having executables is months if not nearly a year down the track. However plans to push to package management systems beyond PYPI are entirely on track. Brew requirements will be the next push we work towards, as well as Windows and Linux compatible package managers!

Custom themes - Add your own QSS stylesheets to the themes folder!

Access themes via View > Themes menu or the Settings button. Our theme collection ranges from beautiful to... questionable. No judgment - use what makes you happy!

Theme Credits:

GTRONICK - QSS themes Inspiration (Neon Button Styling)
Unreal Stylesheet - Unreal Engine-inspired themes
Dunderlab Qt-Material - Material Design inspiration (we created custom compatible themes inspired by their brilliant work)
QSS Themes Repository - Our custom collection (Which hasn't been updated in months on the repository)

Note on Material Themes: We previously used the qt-material dependency from Dunderlab, but found its overstyled QSS caused some UI glitches and compatibility issues with PyQt6 widgets. We've replaced it with our own Material Design-inspired themes that maintain the aesthetic while ensuring better compatibility with our application. Full credit to the Dunderlab qt-material project for the inspiration - their work is brilliant, we just needed themes specifically tailored to our widget structure. Screencaps from our local insallation still show MATERIAL themes installed, that's because one of us forgot to do a re-install.
