Title: Innovating Language Learning: My Journey Developing a Multi-Language Sentence Analyzer
Creating a language learning tool from scratch can be a challenging yet rewarding experience. Recently, I embarked on an exciting project aimed at helping my wife better understand Korean grammar, which has now evolved into a robust platform serving nearly a thousand users.
The inception of this project was humble—a one-evening MVP built with Next.js that utilized the Gemini API to analyze Korean sentences and display color-coded grammatical structures. What began as a simple prototype quickly gained momentum. Today, the platform, which I’ve affectionately named “Hanbok,” processes hundreds of analyses daily and has accumulated over 40,000 analyses to date.
Over the months, I’ve made significant improvements and added new features to enhance user experience. These include spaced repetition flashcards for vocabulary retention, support for nine additional languages, song lyric analysis to make learning engaging, and a chat interface that allows users to ask follow-up questions based on sentence analyses.
If you’re interested in exploring the platform, feel free to try out the demo at https://hanbokstudy.com. Your feedback is highly appreciated as I continue to refine the tool.
Technical Stack:
– Frontend built with Next.js
– Custom CSS for unique styling
– Backend powered by an Express web server
– Redis and MongoDB for data management
– GPT-4.1 providing OCR and conversational capabilities
– Gemini API for in-depth language analysis
– Hosted on DigitalOcean with NGINX
Future developments include a dedicated forum for language Q&A, expanding language support based on user requests (such as Vietnamese, Hindi, and Indonesian), and grammar practice quizzes tailored to individual learning histories.
For those interested in the technical side or looking to contribute, the project’s GitHub repository and Discord community are accessible through the site. The journey from a simple MVP to a community-supported platform has been incredible, and I look forward to continuing this adventure to make language learning more accessible and interactive.
