1. ChatGPT — Best All-Round AI Study Assistant
ChatGPT is the most versatile AI tool for students. You can use it to explain complex concepts in simple terms, summarise long readings, generate essay outlines, brainstorm ideas, solve problems step by step, and answer questions on virtually any subject.
The free plan (GPT-3.5) is sufficient for most study tasks. ChatGPT Plus at $20/month unlocks GPT-4 which is significantly better at complex reasoning, maths, and nuanced writing tasks.
Best for: Understanding difficult concepts, essay planning, summarising readings, general Q&A
Student tip: Instead of asking ChatGPT to write your essay, ask it to explain the topic, give you an outline, and suggest arguments. You learn more and produce better work.
2. Grammarly — Best for Writing and Essays
Grammarly is essential for any student who writes essays, reports, or research papers. It catches grammar errors, improves sentence structure, suggests better word choices, and checks for clarity — going far beyond basic spell-check.
The free plan catches basic grammar and spelling errors. Grammarly Premium adds advanced suggestions, tone detection, and a plagiarism checker — worth it for students who write frequently.
Best for: Essays, research papers, emails to professors, any written assignments
Student tip: Use Grammarly’s tone detector before submitting academic work — it flags if your writing sounds too informal for a university submission.
3. Notion AI — Best for Notes and Organisation
Notion is the best tool for organising your student life — lecture notes, assignment deadlines, reading lists, project planning. Notion AI adds an intelligent layer on top: it can summarise your notes, generate study guides from your content, and help you structure complex projects.
The free plan is generous for individual students. Notion AI adds $10/month but pays for itself if you use Notion heavily.
Best for: Lecture notes, assignment tracking, study planning, research organisation
Student tip: Create a Notion database for each subject with lecture notes, key concepts, and exam prep. Then ask Notion AI to generate a summary or quiz questions from your notes before exams.
4. Perplexity AI — Best for Research
Perplexity AI is like a research-focused search engine that gives you cited answers instead of a list of links. For students who spend hours researching papers and assignments, Perplexity dramatically speeds up the process.
Unlike ChatGPT, Perplexity cites its sources — meaning you can verify information and use proper academic references. This makes it significantly more useful for academic research than general chatbots.
Best for: Research papers, finding credible sources, understanding complex topics quickly
Student tip: Use Perplexity to get an overview of a topic with sources, then go to those original sources for your actual citations. Never cite Perplexity itself in academic work.
5. Quillbot — Best for Paraphrasing and Rewriting
Quillbot helps students rewrite sentences and paragraphs in their own words — useful for avoiding accidental plagiarism when taking notes from sources and for improving the clarity of your own writing.
The free plan includes paraphrasing up to 125 words at a time. The paid plan at $9.95/month removes word limits and adds more paraphrasing modes.
Best for: Paraphrasing sources, rewriting unclear sentences, improving writing flow
Student tip: Use Quillbot to rephrase your notes from textbooks — it forces you to engage with the material differently which improves retention.
6. Otter.ai — Best for Lecture Transcription
Otter.ai automatically transcribes spoken audio into text in real time. For students who struggle to take notes fast enough during lectures, Otter.ai is a game changer — it captures everything so you can focus on understanding rather than frantic note-taking.
The free plan gives 300 minutes of transcription per month which covers most students’ lecture loads.
Best for: Lecture transcription, meeting notes, recording study group discussions
Student tip: Record your lectures with Otter.ai and review the transcript the same evening. Highlight key points and add them to your Notion notes for a complete, organised study system.
7. Wolfram Alpha — Best for Maths and Science
Wolfram Alpha is the gold standard for STEM students. It solves mathematical equations step by step, visualises data, explains scientific concepts, and handles everything from basic algebra to advanced calculus and statistics.
Unlike AI chatbots that sometimes make mathematical errors, Wolfram Alpha is a computational engine that gives reliable, accurate answers with full working shown.
Best for: Maths, physics, chemistry, statistics, any quantitative subject
Student tip: Don’t just copy the answer — study the step-by-step working that Wolfram Alpha shows. Understanding the process is what helps you in exams.
How to Use AI Tools Ethically as a Student
AI tools are powerful study aids but using them to submit work that isn’t yours is academic misconduct. Most universities have clear policies on AI use in assessments.
The ethical approach: use AI to understand concepts faster, improve your writing, organise your notes, and research more efficiently — not to generate content you submit as your own work. The students who use AI ethically learn more and produce genuinely better work.
Which AI Tools Should Students Get First?
Start with these three — all have free plans and cover the most common student needs:
- ChatGPT — for understanding concepts and planning
- Grammarly — for improving all written work
- Perplexity AI — for research with citations
Add Notion AI once you have a note-taking system, and Otter.ai if you attend lectures regularly.
