Tips for Using AI Tools Effectively
- Don't copy-paste blindly — AI can make mistakes. Always verify facts and understand the code or content it generates.
- Learn prompt engineering — Better prompts = better outputs. Be specific about what you want.
- Check your college's AI policy — Some assignments may have rules about AI use. When in doubt, disclose.
- Use AI as a learning accelerator — Ask it to explain concepts, not just give answers.
- Combine tools — Use Perplexity for research, ChatGPT for writing, and Grammarly for polishing.
