AI tools for students have a bad reputation — because people think they’re just about cheating. The genuinely useful ones do something different: they help you understand material faster, catch errors in your work, and organise information better. Here are the tools worth your time.
Studying and Understanding Material
Google NotebookLM (Free)
Upload your lecture slides, textbook chapters, or study notes and ask NotebookLM questions about them. It summarises key concepts, generates practice quiz questions from your notes, and creates audio overviews you can listen to while commuting. For exam prep, it’s genuinely transformative — you can quiz yourself on your own materials rather than generic content.
Try this: Upload your lecture notes and ask “Generate 10 practice exam questions based on these notes with answers.”
Anki + AI (Free)
Anki is the gold standard for spaced repetition revision. The AI angle: use ChatGPT or Claude to generate Anki flashcard decks from your notes. Prompt: “Convert these notes into Anki flashcard format (front/back) for spaced repetition revision.” Then import the CSV into Anki. Dramatically faster than making cards manually.
Writing and Essays
Grammarly Free
Grammarly catches grammar, spelling, and clarity issues — better than any spell-checker. The free tier is genuinely useful. The paid tier adds tone detection and plagiarism checking. For non-native English speakers, even the free version significantly improves written work quality.
Using Claude or ChatGPT Ethically for Essays
The ethical use of AI for essay writing: use it to understand the topic better, generate an outline, identify counterarguments to your thesis, and proofread your own writing. Do not use it to write paragraphs you’ll submit as your own — beyond academic integrity issues, the writing won’t reflect your understanding and you’ll struggle in exams.
Good prompt: “I’m writing an essay arguing [position]. What are the three strongest counterarguments I should address, and what evidence would support each?”
Maths and Science
Photomath (Free)
Point your phone camera at a maths problem and Photomath solves it step by step. More importantly, it explains why each step works — making it a teaching tool, not just an answer machine. For algebra, calculus, and statistics problems, it’s remarkably accurate.
Wolfram Alpha (Free tier)
More powerful than Photomath for complex maths and science. Solves differential equations, plots functions, and handles chemistry and physics problems with full working. Essential for STEM students.
Lecture Notes
Otter.ai (Free — 300 minutes/month)
Record your lectures and Otter transcribes them automatically with speaker labels. You can highlight key moments during the recording and the AI generates a summary at the end. For long lectures where note-taking breaks your concentration, this is genuinely valuable.
Research
Perplexity AI (Free)
For research papers and essays, Perplexity is safer than general ChatGPT because it cites sources — you can verify each claim and follow links to primary sources. Always verify citations directly (AI sometimes gets details wrong) but it’s a far better starting point than uncited AI answers.
