How can I tell if my child is using AI for homework?

You usually can't prove a piece of homework was written by AI, but you can tell whether your child understands it, which is what actually matters. AI homework help is now common: in a 2025 Internet Matters survey of UK 9 to 17-year-olds, help with schoolwork or homework was the most common reason children gave for using AI chatbots (42% of users).

Signs to look for

None of these proves anything on its own. Several together are worth a conversation.

• A sudden change in voice. Writing that sounds older, flatter or more polished than your child usually sounds.
• Vocabulary they can't explain. Ask what "juxtaposition" means in their essay. A blank look tells you a lot.
• Answers without working. Correct maths answers with no steps, or steps that don't match how their class is taught.
• Generic examples. Essays full of balanced, safe points and no personal detail, opinion or reference to what was covered in class.
• Speed that doesn't fit. An hour-long task done in ten minutes.
• Confident errors. Made-up quotes, wrong dates or invented sources stated with total confidence.

The conversation test

The best check is friendly curiosity, not interrogation.

• "Talk me through how you got this answer."
• "Which bit was hardest?"
• "If you had to explain this to your little brother, what would you say?"
• "What would change if the number was 12 instead of 8?"

A child who used AI to understand a topic can explain it. A child who copied an answer usually can't, and you've learned that without an accusation.

Why AI detectors aren't the answer

AI-writing detectors give probabilities, not proof, and they can flag genuine work. OpenAI withdrew its own AI text classifier in 2023 because of its low accuracy. Our post on whether AI detection in schools works covers the evidence.

Is it cheating?

It depends on the task and the school. Using AI to explain photosynthesis before writing about it is very different from pasting in an AI essay. For graded coursework the rules can be strict: in England, the exam boards' JCQ guidance treats submitting AI work as your own as malpractice. See how to find out if your child's school allows AI.

The learning cost matters as much as the rules. A 2025 study in PNAS found that high school students who practised maths with unrestricted ChatGPT did 17% worse on exams once access was removed, while a version that gave hints instead of answers largely avoided that harm.

Set family rules instead of policing

Agree what AI is for at home:

Tools that explain rather than hand over answers make this easier. Askie's homework support is designed to explain rather than simply give answers, and parents can review conversation transcripts. Our post AI homework help: does it work or is it cheating? goes deeper.
