About

Launched in March 2024, Complement aims to improve the digital learning experience for all, with a digital twin of the trainer.

Our observation

At Complement, we start with a simple observation: e-learning isn't living up to its potential .
Static videos, disconnected quizzes, limited interaction… The result is an often passive, unengaging, and frustrating experience for both learners and instructors.
Our conviction: online learning can be dynamic, oral, and interactive—as seamless as a video call with a live instructor.

👋 Why Supplement?

Because you never learn better than in a one-on-one oral conversation with an expert in the subject, the Complement solution aims to reproduce the experience of private lessons via video conferencing using artificial intelligence technologies.

🧠 A new way to learn

With Complement, an AI avatar presents the course orally, learners' questions assesses them orally , and adapts to their pace.

Students learn by speaking , ask all their questions, rephrase, and progress—as if they were interacting with an expert instructor. It's a conversational e-learning experience designed to captivate those who disengage from traditional formats.

⚙️ Simple to create, designed for trainers

No studio, video equipment, or technical skills are needed.
Simply import a PowerPoint presentation, add text, or dictate verbally—and Complement generates the module, quizzes, and avatar.
In just a few hours, you can publish an engaging, personalized training course, ready for distribution.

"The goal is to create a digital learning experience that is as good as a video call with an expert trainer in the subject, thanks to AI and photorealistic avatars. And for those suffering from ADHD like me, the only way to stay focused during e-learning is a human oral exchange format."
