1. ChatGPT — Best All-Purpose Study Assistant
ChatGPT is the most versatile tool on this list. Students can use it to explain a difficult topic at a chosen level, create a revision timetable, generate practice questions, compare theories, improve an outline, or turn course materials into a study guide.
It is especially useful when the student gives it reliable course material and a precise instruction. For example: “Use these lecture notes to create 20 practice questions. Explain every answer and do not add information that is not in the notes.”
Best uses for students
- Explaining complicated concepts in simpler language
- Creating study plans and revision schedules
- Generating quizzes, flashcards, and practice questions
- Brainstorming essay outlines and presentation structures
- Reviewing a draft for clarity and logical gaps
Important limitation: ChatGPT can make mistakes or invent facts and citations. Students should verify important claims against textbooks, lecture materials, academic papers, or other reliable sources. It should not write an assignment that the student submits as their own work.
2. Grammarly — Best for Grammar and Writing Feedback
Grammarly helps students identify problems with grammar, spelling, punctuation, sentence clarity, and tone. It can be useful during the editing stage of an essay, report, email, scholarship application, or presentation.
The strongest way to use Grammarly is to review each suggestion instead of accepting every change automatically. A technically correct rewrite can still weaken the writer’s meaning, academic voice, or subject-specific terminology.
Best uses for students
- Finding grammar and punctuation errors
- Improving clarity and sentence structure
- Checking tone and consistency
- Polishing emails, essays, and applications
- Documenting AI assistance when required
Important limitation: Grammarly improves writing; it does not verify whether an argument or factual claim is correct. Students must also follow their institution’s rules on AI-assisted writing.
3. Perplexity — Best for Source-Based Web Research
Perplexity searches the web and produces answers with linked sources. This makes it useful for discovering reports, finding background information, exploring a new topic, and creating an initial research map.
Its citations are helpful, but their presence does not guarantee accuracy. Open every important source, check whether it actually supports the sentence, examine the author and publication date, and prefer primary or peer-reviewed sources for academic work.
Best uses for students
- Finding sources and keywords for further research
- Getting an overview of an unfamiliar topic
- Comparing information from several web sources
- Uploading papers for explanation or summarization
- Following citations back to their original pages
Important limitation: Perplexity is a research starting point, not a replacement for academic databases, peer review, or the student’s own evaluation of evidence.
4. Notion — Best for Organizing Notes and Coursework
Notion is an all-in-one workspace for class notes, databases, reading lists, project deadlines, and study schedules. Students can create a page for each course, connect assignments to a calendar, and keep research materials in one structured system.
Notion’s AI features can help summarize content, draft or edit text, and answer questions using information stored in a workspace. However, plan eligibility and access to AI features can vary.
Best uses for students
- Organizing courses and lecture notes
- Tracking assignments and deadlines
- Building weekly study schedules
- Creating reading lists and research databases
- Summarizing notes already stored in a workspace
Important limitation: Notion can become a distraction if students spend more time designing the system than studying. Start with a simple course dashboard and add complexity only when needed.
5. QuillBot — Best for Paraphrasing and Summarizing
QuillBot offers tools for paraphrasing, grammar checking, summarizing, and citations. It can help a student explore clearer ways to express an idea or condense a long passage into key points.
Paraphrasing is not a way to hide copied work. The student must understand the source, rewrite it accurately in their own voice, and cite the original author whenever the idea is not their own.
Best uses for students
- Rewriting unclear sentences
- Comparing alternative wording
- Summarizing long passages
- Checking grammar and fluency
- Creating citations that are then manually checked
Important limitation: Automated paraphrasing can change the meaning or produce unnatural language. Always compare the result with the original source.
6. Khanmigo — Best for Guided Tutoring
Khanmigo is Khan Academy’s AI-powered tutor. Instead of simply giving an answer, it is designed to guide learners through questions and help them reason toward a solution. It works with Khan Academy content across subjects such as mathematics, science, humanities, and coding.
Best uses for students
- Receiving step-by-step guidance
- Practising mathematics and science concepts
- Getting feedback while learning to code
- Identifying gaps in understanding
- Learning through questions instead of answer copying
Important limitation: Direct learner access is not universally available. It can depend on the student’s country, age, parent or guardian, school partnership, and payment eligibility. Students should check the official access requirements before choosing it.
7. Otter.ai — Best for Lecture Transcription
Otter.ai can record speech and turn it into searchable transcripts and notes. It is useful for lectures, online classes, study groups, and interviews, especially when students need to revisit what was said.
Best uses for students
- Transcribing in-person and virtual lectures
- Reviewing searchable class notes
- Capturing study-group discussions
- Finding key points after a class
- Supporting students who benefit from captions
Important limitation: Transcripts can contain errors, especially with noise, accents, or technical vocabulary. Always ask for permission before recording a lecturer, classmate, meeting, or private conversation.
8. Canva AI — Best for Presentations and Visual Projects
Canva combines templates with AI-assisted design tools. Students can use it to create presentations, posters, infographics, videos, and visual reports. Features such as Magic Design and Magic Write can speed up early drafts, but the student still needs to check facts, edit the text, and make the design appropriate for the assignment.
Best uses for students
- Creating presentation slides
- Designing posters and infographics
- Turning ideas into visual layouts
- Creating diagrams and social content for projects
- Improving the visual consistency of group work
Important limitation: A polished design cannot compensate for weak research. Students should also confirm that images, templates, and AI-generated assets are allowed for their intended use.
9. Wolfram|Alpha — Best for Math and Science
Wolfram|Alpha is a computational knowledge engine for mathematics, physics, chemistry, statistics, engineering, and other quantitative subjects. It can calculate results, graph equations, analyze data, and provide step-by-step solutions for many topics.
Best uses for students
- Checking equations and calculations
- Exploring graphs and functions
- Working with calculus, algebra, and statistics
- Solving selected physics and chemistry problems
- Studying a worked solution step by step
Important limitation: Some step-by-step features require a paid Pro plan. Students should use the steps to understand the method, not copy the final answer without learning the process.
10. NotebookLM — Best for Studying from Your Own Sources
NotebookLM lets students create a notebook from selected sources such as PDFs, documents, web pages, audio files, and supported public YouTube URLs. Students can ask questions about those sources, request summaries, and create study material grounded in the uploaded content.
This is more useful than an unnamed “YouTube summary tool” because the student can keep a video together with lecture notes, readings, and other course sources in one notebook.
Best uses for students
- Summarizing course readings and public educational videos
- Comparing information across several selected sources
- Creating study guides from uploaded material
- Asking questions tied to course documents
- Reviewing long source collections more efficiently
Important limitation: The output is only as reliable as the sources provided. A summary may omit context, so students should return to the original material before quoting or making an important claim.

How to Use AI Responsibly at School or University
- Check your institution’s policy. Some assignments allow AI for brainstorming or editing, while others prohibit it.
- Protect private information. Do not upload confidential student records, unpublished research, exam papers, or personal data without permission.
- Verify every important claim. AI-generated answers and citations can be wrong.
- Cite original sources. An AI tool is not a substitute for citing the book, paper, dataset, or website that supports the claim.
- Keep your own voice. Use AI to support thinking and editing, not to replace your understanding.
- Never rely on AI alone for medical, legal, financial, or safety decisions. Use qualified professionals and authoritative sources.
