02 / OUR APPROACH
Our next step for Jubbo is to explore
Claude as part of our content workflow.
We plan to test the Claude API for English practice activities, example sentences, and explanations. We’ll review the content and evaluate its quality before deciding what belongs in the product.
Start with a vocabulary topic, learning level, and a focused content task.
Explore Claude-generated drafts, with developer review for accuracy and clarity.
Evaluate learning value, reliability, and API cost before a wider integration.
Jubbo is in development. The Claude API integration is planned; it is not a live product feature.
03 / THE STUDIO
Ezada Labs is an independent software studio founded by Erhan and Derya. We build across games, learning, and security, with the same attention to the people who will use our work.
Curious about what’s possible.
Careful about what we put into the world.
