      Shared Capabilities

      • Browser-local: file reading, parsing, and processing happen locally — sensitive data stays on your machine
      • Batch input: multi-document paste and multi-file upload throughout
      • Custom Replacement Rules: Chinese Conversion and Novel Processor let you mark "do-not-process" terms (iPhone, OpenAI, custom names)
      • Chainable: split a huge doc → run regex cleanup → convert to Traditional

      Common Combinations

      • Web-novel reading prep: Novel Processor strips ads + fixes chapter headings → Chinese Conversion to TW Traditional → export
      • Machine-translation prep: Text Splitter chunks a long doc at 5000 characters (the Google / DeepL free-tier cap) → Text Toolbox regex-cleans each chunk → export segment files
      • Multilingual archive cleanup: Text Toolbox filters out Japanese lines → Chinese Conversion to Simplified → Text Splitter by paragraph
      • Spreadsheet data into a database: paste Excel columns into Text Joiner → SQL VALUES preset builds the INSERT → verify against production with Text Diff
      • Revision review: drop the before/after drafts into Text Diff → export a .patch for the record
