AI Homework Help: Answers or Understanding? App Comparison

Maybe you know this moment: your child is sitting in front of a math problem, you're right in the middle of cooking dinner, and someone mentions that there are apps that "simply explain" homework. Sounds good. At the same time, a quiet voice pipes up: will my child actually learn anything, or will they just let the AI do it?

That worry is valid. But it doesn't apply equally to all apps. Behind the label "AI learning help" hide two fundamentally different approaches, and the difference decides whether your child gets smarter or just gets done faster.

Answer AI vs. explainer AI: the crucial difference

Picture two tutors. One looks at the problem, writes down the answer, and leaves. The other asks: "What does it say here? What do you already know? What could the first step be?" Both "help." But your child only learns something with one of them.

AI apps come in exactly these two types:

Answer AI works on a simple principle: photo in, solution out. Your child photographs the problem, the app shows the result, often with the working steps to copy. That's handy when an adult wants to check a solution. For an elementary school child, it's an invitation to copy. The homework gets done, but nothing gets understood.

Explainer AI doesn't just write down the finished solution. It explains what the problem is asking, breaks it into small steps, and lets the child answer for themselves. Only once the child gives their own answer do they get feedback: correct, almost correct, or take a closer look here. The thinking stays with the child.

The difference sounds subtle, but it's fundamental. With one approach, the AI does the homework. With the other, it does what a patient adult with a bit of time would do: guide instead of giving answers.

Why the fear of cheating is justified

Parents who are skeptical of AI apps aren't wrong. With answer apps, the risk of cheating is real, for a simple reason: children of elementary school age take the path of least resistance. That's not a character flaw, it's completely normal. If the app shows the solution, an eight-year-old will copy it. Period.

You're not alone with this worry: in a Forsa survey commissioned by Raabe Verlag (in German) from 2023, 73% of the parents surveyed feared that AI tools make it easier to cheat on tests and homework.

The problem shows up later: the homework is done, but on the test your child is on their own, without the app and without the understanding the homework was supposed to build. The teacher wonders about the gap between the notebook and the test, and your child has learned: when it gets hard, there's a shortcut.

A study with teenagers supports this concern. In an experiment with about 1,000 students in grades 9 to 11 in Turkey, described by the OECD Digital Education Outlook 2026, teenagers who used a general chatbot while practicing did worse on an unaided test than students who studied on their own. Those who practiced with a guiding learning chatbot did about as well as the self-study group, but not better. The study wasn't run with elementary school children, and it doesn't show any learning advantage from AI either.

By the way, many of these apps aren't built specifically for elementary school children. Photomath, for example, covers everything from elementary school to university according to its own website (photomath.com) and shows the solution along with the working steps, and ChatGPT isn't a children's product either. We took a detailed look at why a general chatbot is problematic for elementary school children in the article ChatGPT and Homework: What Parents Should Know.

The good news: when choosing an app, you can pay attention to how it's built. An app that explains the path first and lets the child answer on their own invites them to think along. Gennady also helps with the solution when your child gets stuck: after a wrong answer and in the last hint. That is why it pays to practice together at the start: think first, then let it check.

The 4-point checklist: how to check an AI learning app

Before you let an app onto your child's tablet, it's worth a quick check. You can answer these four questions yourself in ten minutes, ideally by trying the app on your own first.

1. Does the app explain, or does it solve?

The most important point. Try the test: photograph a problem and see what happens. Does the app show the result right away? Then it's an answer app, no matter how childlike the design looks. Does it guide your child to their own answer with questions and intermediate steps? Then it's working the right way.

It's also a good sign if the app doesn't just correct a wrong answer from your child, but explains where the thinking went off track and offers a new attempt.

2. Is it built for elementary school children?

"Ages 4+" in the App Store doesn't say much. What matters is whether the app was really made for six to eleven year olds:

• Does it speak the language of a second grader, or does it sound like an encyclopedia?
• Can it read problems aloud? Beginning readers can't read long explanations themselves.
• Can your child answer by voice, instead of having to type?
• Are the explanations short and broken into small steps, or walls of text?

3. What about data privacy and child safety?

With an app like this, your child photographs worksheets, records spoken answers, and maybe their name is written in the notebook. So take a close look:

• Is there an understandable privacy policy that says what happens to photos and voice recordings?
• Is there a parental gate, so your child can't make purchases or change settings on their own?
• Is data used for advertising or sold to third parties? For children's apps, that's a clear dealbreaker.

You can read how Gennady handles these points on our safety page.

4. No ads, no open chat

Two things have no place in a children's app: advertising, because children can't reliably tell ads from content, and an open chat, where the AI chats about any topic at all. Check this yourself while testing: ask the app something that has nothing to do with the homework, and see how it reacts.

Here's an overview comparing the two app types:

ChatGPT, Gemini, KIDZCOOL and Gennady compared

What does this look like with actual products? Here are four AI helpers at a glance: two large general-purpose AIs with a learning mode, and two products built for elementary school children. Transparency note: Gennady is our own product.

ChatGPT is allowed from age 13 according to the provider (in German), teenagers aged 13 to 17 need parental consent. In a normal chat, ChatGPT answers directly. Since July 2025 there's been a study mode (in German) that holds back direct answers and guides step by step with questions. But it can be switched off again at any time during a chat, and which elementary school child turns it on by themselves?

Gemini from Google also requires users to be at least 13 years old (in German) for a personal account. For child accounts with parental supervision, the Gemini apps are not available (in German) in the European Economic Area and Switzerland, so not in Germany or Austria either. Since August 2025, Gemini has had its own learning mode called Guided Learning, which according to Google is meant to foster deeper understanding rather than just answers.

KIDZCOOL from Detmold, Germany targets grades 1 through 4 (in German): the child photographs the worksheet, the AI recognizes the problems, and helps in four stages. According to the website, the solution is only revealed once a parent unlocks it with their PIN.

Gennady is built for children ages 6 to 11. How it works and when the solution becomes visible is in the table and further below in the section "Where does Gennady stand?".

How we compared: as of September 2026. Based on the providers' own statements on their websites and help pages, as well as the reports linked above. We did not run our own long-term test; "not checked" means we did not verify that point ourselves.

Guiding AI use at home: how to make it work

Even the best app doesn't replace your guidance, especially at the start. The US organization Common Sense Media recommends that children ages 6 to 12 only use AI chatbots under adult supervision. A few things have worked well:

Introduce the app together. Sit with your child during the first week. Not to supervise, but so your child understands what the app is meant to be: an explaining helper, not an answer machine. Feel free to say openly: "The app explains the path to you. Try it yourself first, then it shows you if it's right."

Agree on clear rules. For example: try it yourself first, then ask the app. The app is the second stop, not the first. That trains exactly the persistence your child will need later on tests.

Keep talking about it. Ask now and then: "What did the app explain to you today?" If your child can tell you in their own words, they understood it. If not, that's a good reason to take another look together. You'll find more ideas for relaxed afternoons in our guide Homework Without Stress.

Ask at school. What does the teacher think about AI for homework, and are there school rules about it? If you follow the same approach at home, your child won't have to switch between two different rulebooks.

Observe, don't monitor. You don't have to track every session. But check in regularly on how your child is using the app, and whether they're improving or just staying busy.

Honest limits: what AI can't do

To be clear: even a well-built explainer AI is no miracle cure.

• AI makes mistakes. Even modern models sometimes calculate something wrong or misread a handwritten worksheet. Google itself writes about Gemini that it can produce AI hallucinations and present false information as fact. Mistakes like this can happen with any AI tool, including Gennady. If an explanation sounds off, take a look at the school notebook together or ask the teacher.
• AI doesn't replace a teacher. It doesn't see what was discussed in class, doesn't always know the class's method, and doesn't notice when your child is having a bad day. If difficulties persist, the way forward leads to the teacher, not the App Store.
• AI doesn't replace you. Attention, encouragement and celebrating a solved problem together: no app can do that.

A good AI learning tool is there for the moments when you can't help right now, or when the third explanation of the same problem tests your patience. No more, but no less either.

Where does Gennady stand?

We deliberately built Gennady as an explainer AI for elementary school children. Your child scans the worksheet, gets the method explained step by step in a kid-friendly way (read aloud on request, with word highlighting for beginning readers), and then answers themselves, by voice, text or photo. Gennady checks your child's answer and, if it is wrong, shows the correct solution for comparison. If your child can't get any further, the last hint shows the solution, so they don't stay stuck. Correct answers earn stars. There are no ads, and signing out, deleting the account and redeeming vouchers are protected by a math problem for parents.

The best way to find out if this approach fits your family is to try it yourself. And if you want to know specifically how Gennady differs from a general chatbot, take a look at our Gennady vs. ChatGPT comparison.

AI for homework is neither a curse nor a magic trick. What matters is which kind of AI you bring into your home: one that gives the answers, or one that helps your child understand. With the checklist above, you can make that decision with confidence.
