The classic mistake when choosing an AI homework tutor is that parents want their child to learn, but buy a photo machine that spits out answers in seconds. Split the need into three kinds first: stuck on one problem and needing to see the steps, needing to be questioned step by step until it clicks, or self-studying for exams to find gaps. The product logic behind each is entirely different, and mixing them up only builds dependence.
Match the tool to the person
| Who | Real need | Start with | Why |
|---|---|---|---|
| Upper primary to middle school, stuck on math | Photograph the problem, see the steps, understand it now | Photomath | Math-only specialist; camera input and step breakdowns are the most mature, and the free tier covers daily stuck points |
| Wants to understand, not copy, across subjects | Be guided by questions toward the answer | Khanmigo | From Khan Academy; by design it does not hand over answers, it asks questions and follows the curriculum |
| Many subjects, wants a human backup | Photo solving plus essay and English help | Gauth | Broad subject coverage and, beyond AI answers, a live tutor channel when something is urgent |
| Advanced high school and university STEM | Calculations that survive checking | WolframAlpha | Built as a computation engine; calculus and linear algebra results are the most reliable, not chat-style guessing |
| Mostly writing assignments | Fix grammar and structure without ghostwriting | Grammarly plus a general LLM | One handles expression, the other ideas; keep the line that the student writes first |
On price, paid tiers in this category mostly sit around ten US dollars a month, WolframAlpha Pro is cheaper, and Khanmigo has a free tier plus arrangements for teachers and parents; check the current official pages before paying. Run the free tier for two weeks first; it beats subscribing and letting it gather dust.
Three questions before buying
First, is the child unable, or unwilling to think? If unable, a step-by-step tool like Photomath is a proper rescue. If unwilling, an instant-answer tool makes the problem bigger; a prompt-first design like Khanmigo fits better, and its slowness is the design, not a flaw.
Second, what is the school's line on AI? Many schools allow AI for explanation and checking, but not for producing the submitted work itself. However good the tool, the risk of crossing that line is yours, so prefer products that show process and steps you can point to if questions come.
Third, data and accounts. Photo solvers upload pictures of problems; when a child's information or school materials are involved, read the privacy terms first, and do not trade personal data for convenience. With products that include human tutors, like Gauth, also check where tutoring records live and whether they can be deleted.
Who should not buy
Anyone expecting a tool to replace parental or teacher supervision should buy none of them: they can answer questions but cannot build habits, and the usual outcome of hands-off use is better-looking homework and unchanged exam results. Anyone wanting one app for every subject should also skip photo solvers; Photomath weakens quickly outside math, and forcing it yields half-baked answers. Finally, very young children without basic self-control should not get unlimited answer-type tools; start with guided products used together with a parent.
If only one purchase is allowed: Photomath for middle-school math emergencies, Khanmigo for building independent problem solving, WolframAlpha kept at hand for advanced STEM, and Gauth filling the gaps in other subjects.
