Win Grep is a lightweight visual text filter for Windows that replaces complex terminal commands with an intuitive 3-pane UI (INPUT ➔ FILTER ➔ OUTPUT). Easily filter log files, perform multi-keyword searches in a single pass, clean text noise with Invert mode, and run set operations (merge/intersect/subtract) line-by-line. Features live Regex preview and Unicode support. 100% local, free on Microsoft Store, no background bloat.
