How to Get Started with AI as a Student

1. Use AI to understand, not just produce: Before asking AI to write something, ask it to explain the topic. Understanding first, writing second.
2. Research smarter with Perplexity: Instead of Google for academic research, use Perplexity — it gives cited answers from academic sources, not just blogs.
3. Turn lecture notes into study guides: Paste your notes into Assisters and ask it to generate a summary, key terms list, and practice questions.
4. Use AI for essay structure, not essay writing: Ask Assisters or ChatGPT to outline your argument given your thesis and sources. Write the essay yourself from the outline.
5. Get GitHub Copilot free: If you're a CS student, verify your student status at GitHub Education and get Copilot free — it's $10/mo otherwise.

FAQs

Q: Is using AI tools for essays considered cheating?

A: It depends on your institution's policy. Using AI to generate text you submit as your own without disclosure is academic dishonesty at most universities. Using AI for brainstorming, outlining, grammar checking, and research is generally permitted. Always check your institution's AI policy.

Q: What is the best free AI tool for students?

A: Perplexity for research (cited answers), ChatGPT for concept explanation and brainstorming, and Assisters for writing assistance are the top free options. All have usable free tiers.

Q: Are there AI tools for Indian students in Hindi?

A: Yes — Assisters and ChatGPT both support Hindi. Khanmigo has Hindi content on Khan Academy India. Perplexity also returns answers in Hindi when queried in Hindi.

Q: Can AI help with STEM subjects like math and physics?

A: Yes. Wolfram Alpha is purpose-built for mathematical and scientific computation with step-by-step solutions. ChatGPT is strong for conceptual explanations and working through problem sets. Always verify numerical answers independently.

Q: Does Notion AI work for students on a budget?

A: Notion offers a free Education plan for students with their .edu email. Notion AI is a paid add-on ($10/mo), but the free Notion workspace is excellent for organizing notes and coursework even without AI features.

Q: How do I avoid AI dependency that hurts learning?

A: Use the "explain first, ask AI second" rule. Struggle with a problem or concept for 10–15 minutes before turning to AI. This struggle is where learning actually happens. Use AI to check your understanding, not bypass it.

Q: What is the best AI tool for research papers?

A: Elicit and Perplexity together form a powerful research stack: Perplexity for quick answers with citations, Elicit for deep literature review and paper extraction. Assisters is best for drafting and editing once you have your sources.
