Homework AI, Subject by Subject
What to ask for in each subject, and where a dedicated page goes further.
Ask for the method, not only the result: "solve step by step and explain why each step is allowed". Paste your own working and ask where it went wrong. For a problem on paper, attach a photo with a free account.
The AI math solver page is built around exactly this: typed problems, solved step by step.
Physics, chemistry and biology questions are often about understanding a process. Ask for an explanation with an everyday example, a labelled list of steps, or the formula with what each letter means and its units.
For lab reports, ask what a result means and what could explain an error, then write the conclusion in your own words.
Ask for causes and effects, a timeline, or two sides of a debate. For facts you will cite, turn on web search in the chat so the answer can point to sources, and check them.
Reading a long primary source? With a free account, attach it as a PDF and ask what the author argues and what evidence they give.
Write a few sentences in the language you are learning and ask for corrections with the grammar rule behind each one. Ask for vocabulary lists, conjugation drills or a short dialogue to practise.
Use the AI for an outline, a thesis check or feedback on a draft paragraph. Keep the writing yours: ask "what is weak here?" rather than "write it for me".
The AI writer page has more on planning and editing longer texts.
Paste the code and the error, and ask what the error means and how to find the bug. The AI reads and explains code; it does not run it, so test the fix yourself.
Ask for a hint toward the fix before the full answer, so you can spot the same bug yourself next time.
Use It to Learn, Not to Copy
Any AI answer generator can hand you a finished answer. That feels fast, but it does not help on the test, where there is no chat window. The students who get the most from an AI helper use it like a patient tutor: they ask for a hint first, try the next step themselves, and only then compare with the full solution.
A few prompts make this easy. "Give me a hint, not the answer." "Ask me questions until I get there myself." "Explain it again with a different example." "Check my answer and tell me only whether it is right." Each one keeps you doing the thinking, which is the part that sticks.
It also helps to use the AI after you finish, not only when you are stuck. Paste your finished answer and ask "what would a teacher take marks off for?" or "what did I miss?". That turns homework AI into feedback on your own work, which is the fastest way to find the gaps before a test does.
Follow your school's rules on AI. Many teachers allow it for explanations and feedback but not for work you hand in as your own, and N33 has no tool that hides AI writing. For essays, the AI writer helps you plan and edit a draft you write yourself. When you take notes from a source, a paraphrasing tool can show other ways to put an idea, but the sentences in your notes should end up in your own words.
For math, ask for one step at a time and question each one instead of copying the result. The AI math solver works through a typed problem that way, and photo math does the same from a picture of your worksheet, attached with a free account.
How to Get Homework Help in Four Steps
Works in the browser on a laptop or a phone.
Choose a quick prompt above, such as Science or Give me a hint, or just type your question.
Paste the exact question, your level (for example 8th grade or first-year college) and what you already tried.
Read the explanation and ask follow-ups until each step makes sense. Ask for a simpler version if needed.
Ask for a similar question and solve it alone, then have the AI check your answer.
Better Questions, Better Help
- • Copy the question word for word, including what it asks you to find.
- • Say what you do not understand, not just "help".
- • With a free account, attach a photo of a worksheet or a PDF of the reading.
- • Turn on web search for questions about current events or facts you will cite.
- • Check any answer you rely on: AI can be wrong.

AI Homework Helper: Common Questions
What students and parents ask before they start.
Yes. GPT-5.6 Luna, Claude Haiku 4.5 and Grok 4.5 are free to use without an account, up to a daily limit. Larger models cost energy per message.
Any subject you can describe in words: math, physics, chemistry, biology, history, geography, literature, languages, economics and programming, among others.
Yes, with a free account. Attach up to 5 images or PDFs per message. For PDFs choose a Claude or Grok model; the photo math page has tips for clear photos.
No. AI can make mistakes, especially with long calculations or niche facts. Check important answers, ask the AI to verify its work, or compare with a second model.
That depends on your school's rules. Using it to understand, practise and get feedback is usually fine; handing in AI-written work as your own usually is not.
