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 binary file. You may need to right-click it, go to Properties > Permissions, and check "Allow executing file as program".

Q: Why did it create a folder when I unzipped it?

A: Some systems automatically create a folder named after the ZIP. Since SI Finder is a single standalone file, you can move it anywhere you like after extraction (e.g. to your Desktop) for easy access.

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 standard system locations ensuring your data is not lost even if you move the executable:

• Windows: %APPDATA%\SI-Finder
• Linux: ~/.local/share/SI-Finder

Q: How do I uninstall SI Finder?

A: Since SI Finder is a portable application, the process depends on your OS:

• Windows: Simply delete the SI-Finder.exe file. You can also remove the database folder at %APPDATA%\SI-Finder.
• Linux: If you used the automatic setup, run these commands in a terminal:
  rm ~/.local/share/applications/si_finder.desktop
rm -rf ~/.local/share/SI-Finder/
