### Common Workflows
1. **Document Analysis**: Convert contracts, reports, or papers → paste Markdown into ChatGPT → ask for summaries, insights, or action items
2. **Knowledge Base Creation**: Convert document libraries → use Markdown for RAG systems → power AI chatbots with accurate retrieval
3. **Content Repurposing**: Convert slides or PDFs → ask Claude to create blog posts, FAQs, or training materials
4. **Research Assistance**: Convert academic papers → ask AI to explain concepts, compare findings, or identify gaps

### Best Practices
- Convert to Markdown first, then paste into AI assistants
- For long documents, convert sections separately to stay within context limits
- Use AI Vision (Premium) for scanned documents before uploading to AI
- Verify table conversion accuracy for financial or data-heavy documents
