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.
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.
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.
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."
