• Real-time editing: Edit results before saving
• Format preservation: Maintains document structure when possible
• Grammar highlighting: Visual feedback for corrections
• Independent tools: Use each tool separately or chain them manually

Dependencies

The app uses several optional libraries:

• python-docx for DOCX support
• PyMuPDF for PDF processing
• language-tool-python for grammar checking
• textblob for spell checking
• spacy for NLP processing
• transformers for advanced paraphrasing
• nltk for WordNet synonyms

• DOCX/PDF format preservation is best-effort
• Tools work independently - no automatic chaining
• Supports undo functionality for easy experimentation
