Case Study: OneClass achieves faster e-learning content creation and 30% lower tutor workload with Looker

OneClass Maximizing learning outcomes and efficiency with AI

OneClass, an e-learning company, was looking to improve learning outcomes and operational efficiency while reducing the workload on its counselors and tutors. Using Looker alongside Google Cloud AI capabilities, including Vertex AI and Gemini, the company needed a faster way to create study materials, respond to students, and support more personalized guidance.

Looker and Google Cloud helped OneClass automate content and report generation, enabling counselors to focus on reviewing and editing rather than drafting from scratch. The results were strong: tutor workload dropped by 30%, image creation for vocabulary flashcards became five times faster, and more than 90% of images generated by Imagen 3 were usable, compared with 30% from similar tools.
