REQUEST

The client asked us to strengthen the existing platform and expand it with new learning and assessment features focused on exam preparation. Our task was to improve stability, introduce AI-assisted study tools, and give teachers better ways to evaluate student progress within the same system.

CHAllENGE

We had to audit the existing platform, identify stability and performance gaps, and define a clear roadmap. Our team needed to introduce AI-powered study features that support exam preparation and fit into the current learning workflows for both students and teachers.

OUR SOLUTION

Yojji experts strengthened the platform by improving code validation and core workflows to make everyday use more reliable. We introduced Deep Reader for AI-assisted reading and added grammar exercises and teacher-created quizzes. Students got better study tools and educators - clearer ways to assess progress.

Core Features

Stabilization of Current Functionality

Our team reviewed critical workflows across the platform and tightened validation at key points where errors previously occurred. By improving code quality and enforcing business rules at the system level, we reduced unexpected failures and made everyday learning and assessment flows more predictable.

Deep Reader

A new feature, Deep Reader, helps students work with complex texts more effectively during exam preparation. It lets students and teachers analyze chapters together, add notes, and ask AI for explanations or clarifications. Reading activity became an active, guided process instead of a passive task.

Grammar Exercises

We added a structured grammar exercise module that helps students practice spelling, punctuation, and sentence structure in short, focused sessions. The exercises reinforce core language skills and give teachers a clear view of where students have problems and what to improve over time.

Quizzes

A quiz system allows teachers to create topic-specific assessments and assign them directly to students. Results appear immediately. It helps educators identify knowledge gaps and give timely, targeted feedback without manual grading.

Results

  • 10 months to stabilize the platform and deliver new AI-powered learning features on web and mobile.
  • 3 major features released: Deep Reader, grammar exercises, and teacher-driven quizzes.
  • Up to 30% faster content comprehension, based on student interaction with AI-assisted reading sessions in Deep Reader.
  • Teachers can create quizzes in minutes, replacing manual preparation that previously took hours.
  • Hundreds of concurrent learning sessions supported without performance drops after stability improvements.
