Overview
Synapic automates image catalog tagging using vision-language models running entirely on your local machine. It generates categories, keywords, and plain-language descriptions without relying on cloud services.
How It Works
Synapic consists of two processes that communicate over a local HTTP connection:
- Avalonia UI (C#) – handles the wizard interface, Daminion server integration, and the processing loop that writes metadata back to files or the catalog.
- Python sidecar – responsible solely for model loading and inference. It never touches the filesystem except to read the image it is asked to tag.
The sidecar launches automatically with the application, waits until the model is ready, and tags images on demand. When the app closes, the sidecar shuts down cleanly — nothing lingers in the background.
Key Features
- Local models only – runs on Hugging Face vision-language models (LFM2.5-VL-1.6B and similar). CPU or CUDA supported, with automatic fallback.
- Two data sources – tag a local folder recursively, or connect directly to a Daminion server to tag items within a catalog or scope.
- Probability scoring – tier-annotated confidence scores accompany each plain-language description, allowing you to trust or re-tag results as needed.
- Bulk processing – includes a progress view with ETA, live colorized logging, pause, abort, and per-item retry capabilities.
- Metadata writing – writes EXIF/IPTC for JPEG, tEXt/iTXt for PNG and TIFF, plus direct writes back to Daminion.
- Deduplication – perceptual hashing (pHash/dHash/aHash/color-moment) identifies near-duplicates, with side-by-side comparison and bulk tag/move/delete actions.
- Results & export – review results in a grid and export to CSV for further analysis.
Cross-Platform Support
Windows builds are available now. macOS and Linux are in development, planned for 2027 if there is demand. Windows installers ship now, and model weights can either be baked into the installer or downloaded on first run. A lite installer is available if you prefer to download the model yourself.
