Frequently Asked Questions
Is it OK for students to use AI tools?
AI tools are permitted for many academic tasks — research, note-taking, grammar checking and study planning. Always check your institution's AI policy before using AI for written assignments. Using AI to cheat or submit AI-generated work as your own violates most academic integrity policies.
What is the best free AI tool for students?
ChatGPT is the most versatile free AI tool for students — it explains concepts, helps with research, gives feedback on writing and assists with problem-solving. Perplexity AI is better for sourced research. Grammarly is the best free proofreading tool.
Can AI help with essay writing?
AI tools like ChatGPT and Grammarly can help students improve their writing — suggesting better phrasing, catching errors and explaining how to structure arguments. Using AI to write an entire essay and submitting it as your own work is academic dishonesty. Use AI as a tool to improve your writing, not replace it.
