reverscan

The application creates a local index of text, images, PDFs, and document files on a Mac, allowing users to retrieve items by entering keywords, typing file names, or providing a visual query such as a screenshot or dropped file. By comparing the visual content of the supplied image with the indexed material, it can surface original, similar, or related files without requiring the exact filename.

It targets professionals who frequently handle large collections of visual and textual assets—designers, marketers, and photographers—who may need to locate a file based on its appearance, a low‑resolution copy, or an unknown name. The tool is positioned as a way to reduce the time spent searching for assets, especially in workflows where files are renamed, archived, or only partially remembered.

The software runs entirely on the local machine, keeping all indexed data private and avoiding any network transmission. It is distributed as a free macOS download, requires no signup, and is listed as experimental.
