Best Free AI Tools: Honest Picks by Task
The best free AI tools organised by task: writing, research, images, transcription, coding and presentations, with what free plans include and privacy tips.
How students can use AI to learn: explaining topics, quizzing, feedback on drafts and study plans, plus school rules, citing AI, privacy and mistakes to avoid.

AI chatbots can make studying faster and less lonely: they explain a topic five different ways, test you at midnight before an exam and point out where an essay argument is weak. They can also do your homework for you, which feels like a shortcut until the exam, when you’re on your own. The difference lies in who does the thinking. Here’s how to use AI as a tutor, not a ghostwriter.
Policies vary hugely between schools, universities, courses and even individual assignments. Some ban AI entirely, some allow it for brainstorming or feedback, and some expect it and ask you to show how you used it. Before you start:
Submitting AI-generated work as your own where it isn’t allowed is usually treated as academic misconduct, with the same consequences as plagiarism.
Ask for a concept explained simply, then with an analogy, then at exam level. Follow up with “Why?” until it clicks. If a textbook paragraph confuses you, paste it in and ask what each sentence means.
Testing yourself is one of the most effective ways to learn. Ask AI to write practice questions from your notes, mark your answers and explain mistakes. Ask for harder questions as you improve.
Tell the chatbot not to give you the answer:
I’m studying [topic] for [course/level]. Act as a tutor.
Don’t give me the answer. Ask me one question at a time,
give hints if I’m stuck, and tell me when I’ve got it right.
Share a draft you wrote and ask for feedback on structure, clarity and whether your argument is supported, without rewriting it for you. You stay the author; AI acts like a critical reader.
Give it your deadlines and exam dates and ask for a realistic revision timetable with breaks. Then adjust it to how you actually work.
After studying a topic, explain it back to the chatbot in your own words and ask it to point out gaps or mistakes. Teaching something is a powerful test of whether you really understand it, and it shows you exactly what to review before the exam. Ask for one follow-up question on each weak spot.
Hold a simple conversation in the language you’re learning, ask for corrections and request vocabulary lists on topics you find hard.

If your course allows AI use, you may need to acknowledge it. Major style guides, including APA and MLA, publish guidance on citing generative AI, usually naming the tool, the version or date and what you asked. Some instructors also want an appendix with your prompts. When in doubt, disclose.
Some institutions use tools that claim to detect AI writing. They are unreliable: they can flag human writing, especially from non-native English speakers, and miss edited AI text. If you’re wrongly accused, your drafts, notes and version history are your best evidence. Our article on why AI text detectors fail explains the problem.
General chatbots handle most study tasks; see our ChatGPT vs Claude vs Gemini comparison. For reading heavy material, tools that answer from your own uploaded notes or papers reduce made-up answers; see how to summarise PDFs safely. Many useful options are free; see our best free AI tools.
It depends on your school’s rules and how you use it. Getting explanations or practice questions is usually fine; submitting AI-written answers as your own usually isn’t.
Detectors are unreliable, but teachers often notice writing that doesn’t match your usual voice, lacks specific course material or cites sources that don’t exist.
Follow the style guide your course uses. APA and MLA both publish formats for citing generative AI, typically including the tool, the date and your prompt.
