Client Profile

The client is a language learning platform in the EdTech industry that uses AI-powered tools to improve language instruction. It helps educators by automating lesson creation, assessments, and curriculum planning, making it easier to develop and scale high-quality language courses.

For teachers, the platform provides AI-generated lesson materials, automated quizzes, adaptive learning paths, and real-time student progress tracking. Educators can customize content, adjust AI recommendations, and monitor student performance to improve learning outcomes.

For students, the platform offers real-time grammar and writing feedback, speech recognition for pronunciation practice, interactive dialogues, and AI-generated educational videos. It adapts to each learner’s skill level and learning style, creating a personalized and engaging language learning experience.

Challenge

Manual Content Creation

Educators spend 8–12 hours per week developing lesson materials, exercises, and assessments. Creating structured, level-appropriate content is time-consuming, reducing time for student engagement and curriculum expansion, affecting content scalability.

Limited Personalization

Pre-set curricula lack adaptability, failing to address individual student proficiency, learning pace, and engagement styles. Without dynamic adjustments, students may struggle with content that is either too advanced or too basic, leading to gaps in comprehension and reduced learning efficiency.

Scalability Issues

Expanding course offerings requires significant manual effort in lesson planning, content creation, and assessment design. As new languages, proficiency levels, or topics are introduced, educators must develop materials from scratch, making it difficult to scale efficiently while maintaining content quality and consistency.

Lack of Interactive Learning Tools

Traditional text-based lessons and static exercises fail to engage learners, limiting opportunities for active participation, real-time feedback, and immersive practice. Without interactive dialogues, speech recognition, or adaptive exercises, students struggle to develop practical communication skills and remain engaged in the learning process.

Cultural & Linguistic Accuracy

AI-generated content must accurately reflect cultural context, idiomatic expressions, and regional language variations to ensure authenticity. Without proper adaptation, lessons may include unnatural phrasing, incorrect cultural references, or generalized translations, reducing their effectiveness and relevance for learners.

Solution

Automating Content & Assessment Creation

The AI-powered system simplifies lesson and assessment creation, saving educators time. Using advanced language models (LLMs) and optimized prompts, it generates high-quality lessons, quizzes, and personalized feedback tailored to different skill levels.

By automating articles, dialogues, grammar exercises, and quizzes, the platform helps educators scale their curriculum efficiently while ensuring accuracy and consistency.

Personalization & Adaptive Learning

The AI system analyzes each student’s progress, strengths, and weaknesses to dynamically adjust exercises, recommendations, and difficulty levels. This ensures that learners receive personalized instruction rather than a one-size-fits-all curriculum.

• User Profiling & Skill Assessment — When students enroll, they take a diagnostic test to assess their language level, learning style, and goals.
• Adaptive Learning Engine — The AI monitors student progress in real time and adjusts lesson difficulty, exercises, and recommendations based on their performance.
• Dynamic Feedback Loop — AI analyzes quiz results, time spent on activities, and mistakes, adapting future lessons to focus on areas that need improvement.
• Custom Learning Paths — Educators can modify AI recommendations, ensuring the right balance between automation and teacher input.

AI-Powered Writing & Speaking Feedback

The platform provides instant writing corrections and interactive speaking exercises, helping students improve grammar, sentence structure, and pronunciation. AI feedback points out mistakes, explains corrections, and gives helpful suggestions. For speaking practice, the system uses speech recognition to check pronunciation and fluency, giving real-time guidance. This allows students to keep improving their writing and speaking skills on their own, without always needing an instructor.

Interactive & Engaging Learning Materials

The platform uses AI-generated dialogues, speech synthesis, and videos to create real-life conversations and cultural situations. Students can practice role-play scenarios, such as ordering food, having a job interview, or asking for directions. AI-powered speech synthesis helps with pronunciation, while interactive videos with subtitles improve vocabulary and listening skills. These tools make learning more practical and engaging, helping students feel more confident using the language in real situations.

AI-Driven Speech & Video Learning

The platform improves listening and speaking skills using Text-to-Speech (TTS), speech recognition, and AI-generated videos for a more interactive learning experience.

• Text-to-Speech (TTS): Converts written text into natural-sounding speech with different accents, adjustable speed, and tone. It highlights key sounds to help with pronunciation.
• Speech Recognition & Feedback: AI listens to spoken responses, compares them to the correct pronunciation, and gives instant feedback on fluency and accuracy.
• AI Video Generation: Creates animated videos from lesson content, including dialogues, vocabulary visuals, and cultural context to improve understanding.

AI-Assisted Curriculum Planning & Progress Tracking

The AI assistant creates lesson plans based on learning goals and keeps them aligned with the curriculum. It tracks student progress by analyzing quiz results, completed activities, and learning trends. Educators can use this data to adjust lesson difficulty, address weak areas, and improve teaching strategies.
