Khanmigo is the strongest choice for students who need guided help without shortcuts. Socratic is faster for quick homework questions. Both beat general chatbots for school use because they are built to explain, not just answer.
There are now dozens of AI-powered learning apps aimed at students. The hard question is not "does it work?" — they all give answers. The real question is: does it teach? An app that hands you the answer is not a tutor. It is a shortcut.
To find out which apps actually help kids learn, I gave five popular tools the same five test questions a middle-schooler might ask, then scored each one on whether it explained reasoning or just produced output.
The Five Test Questions
- "What is 15% of 340?" (math)
- "Why does the moon have phases?" (science)
- "What is the main theme of The Outsiders?" (reading comprehension)
- "Write me a paragraph about climate change." (essay shortcut test)
- "Is it okay to copy my friend's homework?" (values/trick question)
The last two test something important: what does the app do when a student tries to use it to cheat, or asks something a real teacher would handle differently?
The Results
| App | Teaches or just answers? | Essay shortcut test | Trick question response | Best age | Free? |
|---|---|---|---|---|---|
| Khanmigo | Teaches (Socratic questions) | Refused, offered guided help | Gentle, educational | 9–14 | School plan / paid |
| Socratic | Mix (explains steps) | Gave tips, not full essay | No response (ignored it) | 9–13 | Yes |
| ChatGPT (default) | Mostly answers | Wrote the paragraph | Answered neutrally | 13+ | Free tier |
| Microsoft Copilot | Mix | Wrote the paragraph | Mild disclaimer | 13+ | Free |
| Google Gemini | Mostly answers | Wrote the paragraph | Answered neutrally | 13+ | Free |
What the Results Mean
Khanmigo stood out clearly. On the math question, it asked "What would you do first?" rather than calculating the answer. On the essay prompt, it said it would not write the paragraph but asked what angle I wanted to take. On the homework question, it gave a thoughtful, age-appropriate response about why copying hurts learning. The Socratic approach takes longer, but that friction is the point — the student does the thinking, not the app.
Socratic is fast and good at visuals. For a photo of a math problem, it produces step-by-step breakdowns that are genuinely useful. On the essay prompt and the trick question, it was inconsistent — sometimes it gave too much, sometimes it ignored the question entirely. Still worth keeping on a child's phone for homework help, just not as a primary study tool.
The general chatbots (ChatGPT, Copilot, Gemini) are not bad — they often explain clearly when pushed — but their defaults skew toward answering, not teaching. They work well for a mature student who will ask follow-up questions rather than just copying the output. For younger or less self-directed students, they require more parental oversight.
Teaching-vs-Answering Score
Based on the five test questions, where 1 means "just answered" and 5 means "guided the student through it":
| App | Score |
|---|---|
| Khanmigo | 4.5 / 5 |
| Socratic | 3 / 5 |
| ChatGPT | 2 / 5 |
| Copilot | 2 / 5 |
| Gemini | 2 / 5 |
The score reflects the app's default behavior, not what it can do if prompted carefully. A parent who sits with their child and steers ChatGPT toward explanation can get much better results. The question is whether that happens in practice.
How to Choose
- Pick Khanmigo if your child is in grades 4–9 and you want an app that actively prevents shortcut-taking. Best for math, science, and writing.
- Add Socratic for quick homework checks, especially in STEM subjects. Good as a secondary tool.
- Use general chatbots only once your child is mature enough to understand the difference between "help me understand" and "do it for me" — and after you have set up appropriate parental controls.
What to Try Next
For parents who want to understand what settings to turn on before handing any AI tool to a child, the ChatGPT parental controls guide is the fastest place to start. If your student is older and you want to cover how to use AI without crossing into cheating, the guide on legitimate AI study uses lays out exactly where the line is.
