Your teen is using ChatGPT for homework. Now what?
Start with the teacher's rule, then check whether they can do a similar problem with the chat closed. A blanket ban often moves the behavior out of sight. For a grades 6–12 household, a guided tutor the student cannot switch off is a stronger default than hoping they pick Study Mode.
Name the situation without panic
You found a ChatGPT tab, a pasted essay, or work that arrived fluent from a student who cannot start the same problem at the kitchen table. That is a common grades 6–12 problem. It is not a character verdict, and it is not a reason to skip the teacher's rule.
ChatGPT is a general assistant. It will answer the question in front of it. A teen in a hurry will use the tool that finishes the night. The useful parent question is not "how do I catch them." It is "what is the household default when they are stuck."
The teacher's rule is the first line
Teacher and school policies vary, and they are getting more specific. Some permit a chatbot only after the student has attempted the work. Others ban it on anything graded. Using ChatGPT against class rules, or pasting its answer onto graded work, is cheating. The syllabus wins over this page.
Ask the teacher directly. Most appreciate the question. Do not take a product page, including this one, as permission.
Why a blanket ban often leaks
A house rule that says "no ChatGPT" is clear. It is also easy to break on a phone, in a bedroom, or on a friend's device. A ban with no replacement still leaves the student stuck at 9 p.m. with a problem they cannot start. That is when the chat comes back.
This page is not a detection guide. We will not tell you how to conceal use or how to police every prompt. The check that belongs at home is whether they can reproduce the method with the chat closed.
The closed-chat check
Pick a problem like the one they just finished. Close the laptop. Ask them to start on paper and talk through the first step. If they struggle to choose a method, they may need more practice or support. Starting the first step and explaining why provides useful evidence of understanding.
That check is also the house rule that tends to survive contact with a teenager: the teacher's policy wins, attempt the work first, and be able to do a similar problem with the chat closed. It does not require you to become a forensics lab.
A guided default, not another answer box
Replacing ChatGPT with another tool that finishes the problem repeats the same night. The replacement that changes the default is a tutor that guides, hands the step back, and stays on. Lumi is built for that job in grades 6–12. It does not give the answer. A parent sets the student up. Students have no email, password, or login.
A parent sees a practice report: the skill, the minutes, and the exit result. Not the full chat thread. That is how you know the time was practice rather than an answer dump. It is a guided alternative, not a faster way to finish tonight's packet.
We cannot lock every browser on every phone. We can make the schoolwork product the one that teaches. Compare Lumi with Khanmigo and ChatGPT Study Mode if those names are already in the house. Then try the demo.
Questions parents ask
Should I ban ChatGPT at home?
A blanket ban often moves the behavior out of sight. The rule that tends to last: the teacher's policy wins, attempt the work first, and be able to do a similar problem with the chat closed. Put a guided tutor in the default seat for schoolwork so the chat is less tempting as the finish button.
Is using ChatGPT on homework always cheating?
Using it against a teacher's rules, or pasting its answer onto graded work, is cheating. Even when a chat is allowed for studying, it leaves you guessing whether they can do the next problem alone. Read the longer cheating page for the house-rule version of that question.
What should I put in ChatGPT's place?
A guided tutor the student cannot switch off, with a practice report a parent can see. We recommend SmartScroll for a grades 6–12 student. Lumi guides and does not give the answer. It is not an answer app for the packet.
Won't they just use ChatGPT on their phone anyway?
They might. Parent-managed setup does not lock every device. It does mean the product you set up is not the escape hatch, and you can see whether a session was practice. The closed-chat check still belongs at the table.
