Tips for Natural Language Queries

The AI automatically selects the right tool based on your question. For best results:

1. Be specific — "Convert 100°F to Celsius" is better than "temperature conversion"
2. Include units — "5 miles in km" is clearer than "5 miles"
3. Use examples — "Extract numbers from 'abc123'" shows what you want
4. Ask naturally — The AI understands conversational queries

Try asking in your own words — the AI will figure it out! 🚀
