Complete Student AI Tools Overview

Using AI Ethically as a Student

What's allowed (generally):

• Using AI to understand concepts
• Generating practice problems for yourself
• Using AI to brainstorm essay ideas
• Spell-checking and grammar tools
• Using AI to debug your code

What's not allowed (generally):

• Submitting AI-written work as your own
• Using AI to write entire essays/assignments
• Not disclosing AI usage when required
• Using AI on proctored exams (unless permitted)

Always check your school's AI policy. Most now distinguish between using AI as a tool (okay) and submitting AI-generated work (not okay).

"The students winning in 2026 aren't avoiding AI: they're using it strategically to learn faster while others catch up. The edge comes from better understanding, not just better tools."
