AI homework helper: explains the step, checks your work, keeps no transcript

November 7, 2026

Type the problem into nixm and say what you have so far: "I got 14, show me where I went wrong" or "explain the first step only". It walks the step, checks your answer, and asks you the next one back. No account to start, one chat credit a message, and no transcript of what you typed is kept, so the half-finished essay and the wrong answers are not on a server somewhere.

What a homework helper should do

There are two things people mean by "AI homework helper": a machine that produces the finished answer, and a tutor that gets you to the finished answer. The first gets the assignment in, and gets you nothing on the test. The second is slower on the night and faster by the exam. Every tool below can do both; the difference is in how you ask, and this page is mostly about that.

The apps, and what each is built for

Photomath and Gauth are camera-first: point the phone at the problem and get worked steps; Photomath sticks to maths, while Gauth covers every subject. Brainly is an AI study companion built on a large question-and-answer community, good when someone has already asked your exact question. Chegg is a subscription with textbook solutions and expert answers, built for college courses. Khanmigo is Khan Academy's tutor, deliberately refusing to give answers outright and nudging you instead; families pay a subscription, teachers use it free. The general chatbots do all of it with no structure at all. The AI-for-school picture is in AI for students.

Where nixm sits

nixm is a chat, not a camera app: type or paste the problem. What it is built for is the tutor mode. Say what you have, not just what you want: "here is my working, where does it go wrong", "explain why step two is allowed", "give me a similar problem and check my answer". It explains, checks, and can quiz you on it afterwards; a quiz drawn in the chat with clickable answers and right/wrong feedback is how the quiz generator works, and the same chat does it for the chapter you are stuck on.

You can start without an account. Each message costs one chat credit. A free account (email link or Google, no card) comes with starter credits; after that you buy a pack once, with no subscription. No transcript of what you type is kept. The wrong answers, the essay draft and the question you were embarrassed to ask live in a signal that dissolves seven days after it was made unless you extend it, and nothing of it remains once the signal dissolves. Why that matters for school work is in private AI chat with no account.

How to ask so it teaches instead of answers

  1. Paste the problem and your attempt. "I got x = 3" gives it something to correct; "solve this" gives it nothing to teach.
  2. Ask for one step. "Just the first step, then stop" keeps the thinking yours.
  3. Ask why, not what. "Why can I divide both sides here?" is the question the test will ask in another form.
  4. Have it check, then quiz. "Check my answer, then give me two more like it."
  5. For essays, ask for questions, not sentences. "What is my argument missing?" keeps the writing yours; the line between help and ghostwriting is in the best AI for essays.

Free AI homework helper: what free means here

The camera apps have free tiers and a subscription: Photomath's steps are free and Plus adds animated explanations, while Gauth caps free answers. Chegg is a subscription; Khanmigo is a subscription for families and free for teachers. The chatbots have free tiers with daily caps. On nixm you start without an account, a free account comes with starter credits, and a pack is bought once when they run out; no monthly plan.

What it is bad at

Reading a photo of a worksheet: an attached picture reaches the chat as a description, not the exact numbers, so type or paste the problem. Long multi-page assignments in one go: give it one problem at a time. Dates, quotations and figures from memory: it can be wrong, and a chapter pasted in is more reliable than a chapter remembered. And it will write the whole thing if you ask it to; whether that was homework is between you and the teacher.

frequently asked

Is there an AI homework helper that does not need an account?

Yes. On nixm you can start without an account; a free account with no card comes with starter credits, and after that a pack is bought once with no subscription.

Does the AI homework helper just give the answer?

It will if you ask for the answer. Ask for the first step, or paste your attempt and ask where it goes wrong, and it teaches instead.

Can I take a photo of the problem?

Camera-first apps such as Photomath and Gauth are built for that. On nixm, type or paste the problem so every number is read exactly.

Is my homework kept on a server?

On nixm no transcript of what you type is kept, and the conversation lives in a signal that dissolves seven days after it was made unless you extend it.

What subjects does it help with?

Anything that can be typed: maths, science, history, languages, essay structure. For maths, paste the working, not just the question.

Can it quiz me afterwards?

Yes. Ask for a quiz on what you just worked through and it is drawn in the chat with clickable answers and feedback on what you missed.
