Introduction
Sujet Grand Oral sells written subjects for the Grand Oral, the oral exam every French student takes at the end of high school. A student picks a subject in their speciality and gets a complete text: €9.99 for a ready-made subject, €39.99 for one written to order.
Its customers are teenagers, and teenagers no longer start with Google. They ask ChatGPT.
The context: students ask ChatGPT first
Every year, hundreds of thousands of French students prepare the Grand Oral. More and more, their first reflex is ChatGPT: where can I find a written subject, which subject should I pick in economics and social sciences (SES)?
“Our customers are 17. They don't search Google anymore, they ask ChatGPT. If we're not in the answer, we don't exist.”
The result: first in ChatGPT, ahead of the publishers
Ask ChatGPT the question a student would ask, « Tu sais où je peux trouver des sujets de grand oral en SES rédigés ? » (do you know where I can find written Grand Oral subjects in SES?), and Sujet Grand Oral comes first, with the badge « Le plus adapté à ta recherche », the best match for the search.

It comes ahead of Terminale Révisions, Hatier's Actu-SES and Le Robert's Grand Oral guide: established names of French education. ChatGPT even says why it picks it: SES subjects written in full, with an introduction, a development and a conclusion, some over 1,000 words.
Why it works
There is no trick here. The site gives AI assistants exactly what a good answer to the student needs:
- Pages that answer the students' exact question. A student looking for a written SES subject lands on a page about written SES subjects, not on a generic homepage.
- Complete subjects. Each subject is written out in full: introduction, development and conclusion, some over 1,000 words. An AI assistant can see at once that the page holds what the student asked for.
- A clear offer by subject. Ready-made subjects at €9.99 and custom ones at €39.99, sorted by speciality. The answer to "where can I find…" is one click away.
The lesson holds well beyond the bac: the question your customers ask an AI assistant is the page you need to have, written so that it answers that question better than anyone else.
