Support for SI Finder

Q: What is SI Finder?

A: SI Finder (Similar Image Finder) is a desktop application designed to find visually similar images using Perceptual Hashing (pHash). It helps you find duplicates or variations of images regardless of their filename or resolution.

Q: Windows says the app is "Unknown" or "Protected my PC". How do I run it?

A: Because SI Finder is a new, independent application, Windows SmartScreen may show a warning the first time you run it. This is normal for apps without an expensive commercial signature.

To run the app:

1. Click "More info" in the blue warning box.
2. Click the "Run anyway" button that appears.

SI Finder works entirely locally and never uploads your images to the cloud.

Q: How do I install SI Finder?

A: Download the bundle for your OS from Gumroad. These are standalone executables:

• Windows: Run the .exe file.
• Linux: Run the provided binary or AppImage.

Q: How does the sensitivity slider work?

A: The slider adjusts the threshold for "similarity". Lower numbers (0-5) are best for finding exact or near-exact duplicates. Higher numbers (10+) allow for looser variations (similar composition or colors).

Q: Where is the database stored?

A: The application stores its index in a local SQLite database within the user's application data folder, ensuring fast searches without re-scanning your folders every time.
