CleanIt is a command line tool that helps you to keep your subtitles clean. You can specify your own rules to detect entries to be removed or patterns to be replaced. Simple text matching or complex regex can be used. It comes with standard rules out of the box:

• ocr: Fix common OCR errors
• tidy: Fix common formatting issues (e.g.: extra/missing spaces after punctuation)
• no-sdh: Remove SDH descriptions
• no-lyrics: Remove lyrics
• no-spam: Remove ads and spams
• no-style: Remove font style tags like <i> and <b>
• minimal: includes only ocr and tidy rules
• default: includes all rules except no-style
