Do students need to pay for AI tools?
Not for most use cases. ChatGPT Free, Claude Free, and Perplexity Free cover the majority of student AI needs — writing assistance, research, concept explanation, and coding help — at zero cost. Pay only after consistently hitting rate limits during real work.
Is using AI for studying or writing academically dishonest?
Policies vary by institution. Using AI to learn concepts, get feedback on drafts, or check your understanding is generally acceptable. Submitting AI-generated content as your own work without disclosure is widely prohibited. Check your university's specific AI policy.
What is the best AI for research papers?
Perplexity Free — it provides cited sources for every answer, which helps you find real sources rather than hallucinated ones. Always verify AI-suggested references against the actual source before citing them.
