About MindGems
Professional File Management Software for Over 25 Years
MindGems develops professional Windows software focused on file management, data analysis, and system optimization. We have been on the market for over 25 years and are trusted by professionals, home users, and large organizations worldwide.
Our software is used by governments, space agencies, international banks, libraries, game studios, laboratories, and many major companies whose products and services you use every day. We build tools for environments where accuracy, performance, and stability matter.
Our products are designed to handle real-world data - large file collections, mixed formats, network storage, and long-term archives. We focus on engineering quality rather than short product cycles or cloud dependency. Every tool runs locally, giving users full control over their data and privacy.
MindGems is best known for advanced duplicate file and duplicate photo detection technologies. Unlike basic file comparison tools, our software analyzes actual content, not just file names or metadata. This allows accurate detection of exact duplicates, similar images, and redundant data even in complex libraries.

MindGems sets the standard for reliable duplicate detection and does not rely on CRC, MD5, checksums, or similar methods. Those often produce false results and unfortunately are still used by many amateur tools on the market. We introduced the term “Visual Similarity” with our Duplicate Image Finder to clearly distinguish it from the basic duplicate finder tools available on the market.
We maintain long-term support for our software. Many of our tools remain actively used and updated decades after their initial release. This commitment reflects our focus on reliability, backward compatibility, and consistent performance.
Unlike many competitors, we do not publicly list our clients by name. Protecting customer privacy is one of our core values, and we take it seriously. We do not bundle adware, tracking, or third-party components, and we do not upload user data to the cloud.
MindGems remains an independent software developer. Our goal is simple - build dependable tools that solve specific problems and continue to work reliably for years.
