Drop a file straight onto the window, pick one from Finder, or paste your list into the built-in editor with live line numbers.
Blazing fast
Runs entirely on your Mac and chews through thousands of entries per second — no servers, no waiting, no rate limits.
Filter & review
Instantly split the results into valid and invalid entries, scan through them and spot exactly which lines need fixing.
