AI Development: Intelligent Polish Grammar Trainer

AI development for Polish grammar learning

Technologies Used

  • Angular – Frontend framework for an interactive user interface.
  • C# CoreAPI – Backend logic and API processing.
  • OpenAI API – AI-based generation and validation of grammatical cases.
  • MongoDB – Caching system to optimize costs and performance.

Introduction

The Polish language is known for its complex grammatical cases, which can be challenging for learners unfamiliar with this linguistic feature. To simplify the learning process, we developed an AI-backed grammar trainer that generates random Polish nouns and requires users to input their correct grammatical cases in both singular and plural. The system then validates the answers and provides instant feedback on errors.

Project Overview

Our AI development project allows users to:

  • Receive AI-generated Polish nouns for case practice.
  • Enter grammatical case variations for singular and plural forms.
  • Get instant validation and feedback on their responses.
  • Track progress and improve accuracy over time.

Implementation

1. AI-Driven Task Generation & Validation

  • The backend, built in C# CoreAPI, communicates with the OpenAI API to:
    • Generate commonly used nouns for practice.
    • Validate user input and detect grammatical errors.
  • AI ensures accurate assessments and provides explanations for mistakes.

2. Angular-Based Interactive Learning Interface

  • Developed an intuitive frontend using Angular.
  • Users can input responses in a user-friendly interface.
  • Live validation highlights correct and incorrect answers.

3. Cost Optimization Using MongoDB

  • Instead of calling OpenAI API for every request, we use MongoDB caching:
    • Previously generated words and their cases are stored.
    • User responses and AI feedback are cached, reducing API costs.
  • Smart caching lowers OpenAI API usage, making the software efficient and cost-effective.

Results & Benefits

  • AI-driven grammar correction for Polish learners.
  • Instant error feedback to accelerate learning.
  • Reduced OpenAI API costs through MongoDB caching.
  • Seamless user experience with a modern Angular UI.

Conclusion

This AI development project successfully leverages OpenAI, C# CoreAPI, MongoDB, and Angular to create an intelligent Polish grammar trainer. By automating noun generation, validation, and feedback, the software simplifies learning for non-native speakers.
