What these text tools cover
Work with plain text and subtitle files in the browser: count words and characters (including CJK), change letter case and naming styles, clean messy whitespace or HTML tags, remove duplicate lines, sort lists, convert between list formats, compare two texts, preview Markdown, test regular expressions, pick random items from a list, or shift and convert SRT/WebVTT subtitles.
How to choose a text tool
Start from the task: counting or cleaning uses Word Counter or Text Cleaner; renaming-style output uses Case Converter or Slug Generator; side-by-side differences use Text Compare; structured lists use List Converter or Text Sorter; patterns use Regex Tester; subtitle timing uses Subtitle Toolbox.
