Features include chat window pinning, chat history caching, search, filtering, and deletion, light and dark mode, custom API keys, and multilingual support.The initial prototype was built at Coexistence with AI: UofT AI Ethics Hackathon (2025), where we won First Place ($3600) out of 38 project submissions.The current version is built on top of that prototype with all the features mentioned above.
