The Best AI Tools for Students
The AI tools students use to study smarter — essays, math, coding, research and language — with honest guidance on free tiers and academic policy.
Most students only need three tools: one general assistant, one research engine with citations, and one subject-specific tutor.
ChatGPT and Claude both offer strong free tiers. Perplexity is the fastest way to a cited answer for research assignments. Khanmigo remains the safest math tutor.
Always check your institution's AI policy before submitting AI-assisted work. Most universities now allow AI as a study aid; few allow undisclosed AI-written submissions.
For coding students, Cursor's free tier is enough for most coursework. For writing, Grammarly plus one LLM covers editing and drafting.
