Quality Checker for AI-Generated Homework is a startup idea for parents, school administrators, and teachers. A parent who teaches college notices their elementary kid's homework packet looks AI-generated and contains factual errors, but doesn't know how to raise it with the teacher. A thread in r/Teachers drew 55 upvotes and 50 comments between Sep 14, 2026 – Oct 14, 2026. People get by with Manual review and GPTZero, and that still leaves this job open. Hotness is 3.05, Warm. Real but moderate pain. Price-sensitive audience. The thread drew 55 upvotes and 50 comments. Only clumsy or enterprise-only options. A 1-2 week mvp. A first version is a moderate amount of work, about 2 weeks, priced under $10 a month and charged as a free tier and a paid upgrade. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

A way through
A tool that scans homework and worksheets for signs of AI generation and factual mistakes, helping parents and school leaders control the quality of AI-made materials.
MVP scope
- Give parents, school administrators, and teachers a way to do this in one sitting: Scan worksheets for AI-generation tells and factual errors, so parents and admins can flag bad materials.
- Persist the result and show it again after a reload.
- State the empty case when there is nothing to show yet, with one next step.
- Charge later with a free tier and a paid upgrade, under $10 a month. The free path must finish the core job once.

Questions
Is this idea already taken?
People already use Manual review, GPTZero. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Moderate. A tight MVP is about 2 weeks (2 weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is parents, school administrators, and teachers. Charge a free tier and a paid upgrade, and test a price under $10 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
