+# Final Report by Aman Chadha
+
+Project: [JS Internationalization with AI Translation Support](https://github.com/sugarlabs/musicblocks/pull/4731)  
+Mentors: [Walter Bender](https://github.com/walterbender), [Devin Ulibarri](https://github.com/devinulibarri)  
+Duration: July – September 2025  
+
+---
+
+## Project Overview
+
+The aim of this project was to modernize the internationalization (i18n) system of Music Blocks by migrating from the legacy `webL10n.js` framework to i18next, and to introduce an AI-assisted translation workflow to reduce the burden on human translators.  
+
+Key goals included:  
+- Making the i18n workflow cleaner, modular, and maintainable.  
+- Automating missing translations with AI + context-awareness.  
+- Supporting community-driven refinements of translations.  
+
+---
+
+## Achievements
+
+1. Migration from webL10n.js to i18next  
+   - Replaced outdated framework with i18next for modern i18n support.  
+   - Added flexible fallback strategies (cleaned text, lowercase, title case, hyphenated).  
+   - Enabled JSON-based translation files for better maintainability.  
+
+2. AI-Assisted Translation System  
+   - Designed a pipeline to parse `.po` files and extract `msgid`s.  
+   - Generated context automatically by analyzing where each string occurs in the codebase.  
+   - Built a RAG (Retrieval-Augmented Generation) model to store these contexts.  
+   - Integrated Google Translate API to auto-fill missing translations using this context.  
+
+3. Contributor-Friendly Workflow  
+   - Human translators can review AI-generated suggestions instead of starting from scratch.  
+   - New language files can be created or updated automatically.  
+   - Significantly lowers the barrier for contributors to help Music Blocks reach more learners.  
+

+
+## Challenges & Solutions
+
+- Challenge: Extracting meaningful context for each translation key.  
+  Solution: Implemented a RAG approach that links `msgid`s to their source code usage.  
+
+- Challenge: Ensuring migration didn’t break existing functionality.  
+  Solution: Incremental testing with sample `.json` files and stepwise replacement of webL10n.  
+
+---
+
+## Key Learnings
+
+- Infrastructure-level improvements (like i18n) may not be flashy, but they unlock the potential for users from around the world to have access to the program.  
+- Context is essential for high-quality translations — raw machine translation alone isn’t enough.  
+- Clean migration strategy + thorough testing makes adoption smoother for the community.  
+
+---
+
+## Future Work
+
+- Add support for more AI translation providers (e.g., DeepL, OpenAI).  
+- Build a simple web-based review UI for translators to accept/refine AI suggestions.  
+- Automate detection of new/changed strings via GitHub Actions and update translation files dynamically.  
+
+---
+
+## Closing Thoughts
+
+This project was a unique opportunity to contribute infrastructure that strengthens Music Blocks for a global user base. By combining modern i18n practices with AI translation support, I hope this work helps learners worldwide access Music Blocks in their own languages with greater ease.  
+
+I’m deeply grateful to my mentors Walter and Devin, and to the Sugar Labs community, for their support and guidance throughout this journey.
