Text Tools
Count, compare, clean and transform text (word count, diff, regex, case, duplicates)
Count words and characters, compare two texts, test regular expressions, change letter case, remove duplicate lines, sort or clean text, and check readability or keyword density. There are also Unicode style generators for bold, italic, small-caps and upside-down text. To compare two versions use the diff checker; for search patterns use the regex tester.
