KALBA Boost: Adaptive AI Platform for Continuous Language Practice
Idea Link partnered with KALBA to conceptualize and develop KALBA Boost, an educational web platform that seamlessly blends teacher guidance with adaptive AI-driven practice. The platform functions as a smart, continuous learning ecosystem, designed to support students and teachers across all language proficiency levels (A1-C1).
Key Features
- Adaptive AI-Generated Learning Flow
- Interactive Real-Time Practice Modes
- Comprehensive Teacher & Student Dashboards
The Challenge
For language students, true fluency is forged through consistent, independent practice outside of the classroom. Kalba.lt, a leading provider of language courses, identified a critical gap in their traditional learning model:
- Inconsistent Practice & Skill Fade: Voluntary homework often lacked engagement and real-time feedback, resulting in practice completion rates falling and leading to inconsistent progress between lessons. Students struggled to find safe, accessible, and context-aware opportunities to practice speaking 24/7.
- Unsustainable Teacher Workload: Teachers were manually burdened with spending approximately 6 hours per week creating or curating supplementary exercises, limiting their capacity for high-value in-class instruction and personalized student attention.
- Lack of Personalization at Scale: The one-size-fits-all nature of traditional homework failed to adapt to the individual strengths and weaknesses of each learner.
KALBA needed a dynamic, scalable platform that could bridge the classroom-to-home gap, ensuring continuous, high-quality practice while drastically reducing teacher effort.

Adaptive AI-Generated Learning Flow
The platform leverages the OpenAI API to automatically generate a structured learning flow, including weekly topics and grammar exercises tailored to the group's current language level (A1–C1). Teachers maintain ultimate control, with the ability to review, approve, or adjust the AI-created material before it is published, ensuring pedagogical quality and curriculum alignment.

Interactive Real-Time Practice Modes
Students can engage with the AI tutor through two highly effective modes: live speaking sessions and chat-based lessons. Utilizing Supabase Realtime and WebSockets, these sessions provide a safe, low-latency environment for practice. The AI offers immediate, context-aware feedback, correcting grammar and vocabulary on the fly to help students build fluency and confidence.

Comprehensive Teacher & Student Dashboards
Both students and teachers benefit from dedicated dashboards. Teachers gain an analytical overview of group activity and individual performance scores, allowing for targeted intervention. Students can view their personal progress across core skills (speaking, writing, grammar), motivating them through transparent scoring and data to focus their independent practice.
