Screenshot filenames are mostly dates. They do not tell me which error, sentence, product, or webpage made the image worth saving.
Screen Index is a local Mac search app for that pile. It watches the screenshot folder, extracts readable text, stores local search data, and suggests useful names and folders. After the first pass, a full-text index makes recall fast. New screenshots join it without rebuilding the whole library.
Search lives in a small floating panel with a global keyboard shortcut. I can search a phrase, open a match, copy it, reveal it in Finder, or return to the source. For supported browser captures, Screen Index can keep the exact webpage URL. macOS requires explicit permission, so the app explains that request first.
The controls stay familiar: click, Shift-click, Command-click, and Command-A. Batch actions can move files, add tags, open Preview, reveal files, or send screenshots to the system Trash. It does not permanently delete them.
Screenshots can hold passwords, private messages, health records, and unfinished work. The index stays local because search only helps when people trust where the data went.
Screen Index is preparing for release. Read the first-hand guide to the best screenshot tool for Mac for the current feature boundaries, pricing model, and who should choose something else, or visit the official Screen Index site for availability.
