Over 1,000 high school students: Les Écoles Progress rebuilds Pascal into an AI maths teacher that adapts to each student
The AI Sisters Lab rebuilt Pascal’s assistants into one “Maths teacher” agent: lessons, quizzes and corrections, for over 1,000 high school students.



Les Écoles Progress created Pascal, a learning platform focused on mathematics. Pascal had piled up several hundred AI assistants with largely duplicated instructions: heavy maintenance and declining performance.
With the PASCALE project, launched on 13 November 2024, the AI Sisters Lab pooled those instructions and built a “Maths teacher” agent that follows the student’s conversation. Pascal is now used by over 1,000 high school students.
Hundreds of assistants to maintain
Pascal relied on several hundred AI assistants, whose instructions were largely repeated from one assistant to the next.
The brief for AI Sisters: simplify without losing teaching quality, with a starting target of cutting duplicated instructions by more than 70%.
Heavy maintenance
The same instructions, copied across hundreds of assistants, made every change costly.
Declining performance
Pascal’s performance was getting worse.
One student, one pace
The maths teacher had to follow each student through their conversation.
Is your platform piling up AI assistants?
The AI Sisters Lab merges them into one agent that is easier to maintain.






The PASCALE project: one maths teacher
Launched on 13 November 2024, the project was shared between the AI Sisters Lab and the Progress teams.
Pooling the instructions
The AI Sisters Lab merged the assistants’ duplicated instructions.
A dynamic “Maths teacher” agent
It follows the conversation, teaches, offers quizzes and corrects.
On the Progress side
The Progress teams rebuilt the interface, the backend and technical monitoring.
A completed project
The PASCALE project has been delivered. Pascal is used by over 1,000 high school students.

We design with you the agent that follows each student.






What Pascal’s Maths teacher does
One agent that adapts to each student’s conversation.
Teaching
→ Explains the concept as the conversation goes
→ Keeps track of what the student has already covered in the exchange
Offering quizzes
→ Questions to check what has been learned
Correcting
→ Corrects the student’s answers
Results of the PASCALE project
The project is complete. The number of users is reported by Les Écoles Progress.
