About this line counter
A line counter answers a deceptively simple question — how many lines does this text have? The subtle part is the last line: by the rule used here (and by most editors), a single trailing newline ends the final line rather than starting an empty new one, so one⏎two⏎ is two lines, not three. Blank lines in the middle do count, and the non-empty tile excludes them.
The unique count collapses exact duplicates, which makes this a fast sanity check on exports and lists before deduplicating for real. Counting happens entirely in your browser — paste log files or customer lists without anything leaving your machine. Word and character totals come along for free.
