Challenge

The Client's Challenge

Online school China Campus Network created courses with a team of 7 methodologists. Developing one short course took a month. This became a growth bottleneck: scaling the product line at that pace was impossible.

The project was initiated by the CEO: the company needed both an innovative AI product to support Skolkovo residency applications and a real tool to optimize internal processes. The service users are methodologists who previously built everything by hand.

Solution

What We Built

We built a web service with a methodologist's personal account where course generation starts by configuring 15+ parameters. The school's proven methodology — module, lesson, and exercise structure — is baked into the system. Under the hood: a mix of LLMs (OpenAI + Chinese neural networks) for the optimal balance of quality and inference cost.

Key Features

  • Configure target audience, topics, and difficulty level
  • Upload additional materials to enrich the course
  • 15+ customization parameters for structure and content
  • Built-in school methodology: modules → units → lessons → tasks
  • LLM mix (OpenAI + Chinese neural networks) for cost optimization
  • Edit and refine generated content

We weren't sure it was even feasible — we had no AI expertise ourselves. From the very first meetings, Frog Studios showed what was possible and how to get there, offering multiple solution options. Even when we hit dead ends, a way forward always emerged that we were fully satisfied with. We got exactly the product we wanted and continue working together on support and development.
