AI-powered course creation

NOLEJ, a French AI startup, is transforming education by automating content creation for teachers and instructional designers. Their goal is to make learning more accessible and impactful for students and trainees. Using AI, NOLEJ generates interactive content tailored to individual abilities and preferences, helping thousands achieve their educational goals. In their first year, NOLEJ attracted 2,500 users and won prestigious awards, including the ASU GSV Cup final, TechCrunch Battlefield Top 20, and GESAwards.

Our collaboration with NOLEJ started in 2023 when they approached us to test a new language model for content creation. Our solution significantly enhanced the quality and effectiveness of their educational content, leading to a lasting partnership. Today, we support NOLEJ with AI, DevOps, and cloud infrastructure solutions, helping them continue to revolutionise education.

01. Scaling up

NOLEJ set out to upgrade their platform in nine months to handle more users without added costs or complexity. This required a full overhaul of the frontend, backend, cloud architecture, AI integration, and the creation of a secure, cost-effective database.

02. Using AI for personalisation

NOLEJ’s AI-powered courses rely on expert-created content. To personalise learning, they needed an AI solution using large language models to process queries and source materials efficiently, creating tailored, engaging content for each user.

03. Building in-house AI expertise

To maintain quality and safety, NOLEJ opted to build a custom AI solution instead of using standard libraries. They sought a technology partner with deep expertise in generative AI to develop bespoke tools and train their team in AI development.

01. Flexible cloud framework

We built a cloud framework using Kubernetes, Knative, and serverless architecture for efficient scaling, cost control, and cross-cloud flexibility. Kubernetes manages scaling and apps, while Knative simplifies serverless workflows for reliability and efficiency.

02. Serverless architecture

Our serverless components work across any cloud, enabling auto-scaling and pay-as-you-go efficiency. This reduces server management, cuts costs, and streamlines operations.

03. AI Kickstarter

We used our proprietary AI Kickstarter framework for secure, production-ready tools.

• RAG architecture: Combines retrieval and generation for faster, accurate content creation.
• Vector database: Ensures fast, secure data processing with advanced filtering and ranking.
• Prompt engineering: Precise, tested prompts for performance, security, and functionality.

04. Collaborative partnership

From the start, we worked closely with NOLEJ, beginning with a GPT-3.5 proof of concept to improve content quality. Strategy workshops aligned goals, while educational sessions deepened their understanding of AI architecture.

01. Versatile AI engine for eLearning

NOLEJ’s AI engine is scalable and adaptable, integrating user data with language models like GPT-4, Mistral, Gemini, and Claude. It supports multimodal technologies for video, audio, and images, ensuring flexibility and innovation without vendor lock-in.

02. Improved user satisfaction

Creators save an average of 10 hours per project thanks to tailored content generation. By using creators’ source materials as “ground truth,” NOLEJ delivers precise outputs across formats like quizzes, flashcards, and glossaries, earning high satisfaction ratings and eliminating manual corrections.

03. Dynamic product growth

NOLEJ has quickly gained recognition, serving top training organizations and diverse needs. Partnerships with Bpifrance, Hodéfi, and EdTech France bolster their credibility, making them a top choice for training departments, teachers, and educational content creators.
