LangChain

Large language models (LLMs) are emerging as a transformative technology, enabling developers to build applications that they previously could not. But using these LLMs in isolation is often not enough to create a truly powerful app - the real power comes when you are able to combine them with other sources of computation or knowledge. This library is aimed at assisting in the development of those types of applications.

VitalGuide

VitalGuide is an offline emergency assistance app designed to save lives during natural disasters or situations where connectivity is unavailable. The app addresses the critical need for reliable survival guidance and emergency first-aid instructions. It uses a Retrieval-Augmented Generation (RAG) system and the Gemma 2 model to provide quick and accurate answers by leveraging government datasets and trusted sources like PDFs and guides. This is important because FEMA's manual is large and unwieldy, and slower to leaf through than our LLM tool, when the seconds matter. Gemma 2 also has general knowledge that the FEMA manual doesn't have and can be asked follow-up questions if information is unclear. Specialized for individuals, communities, and first responders, it features multilingual support, ensuring accessibility for diverse users. Its unique offline functionality guarantees availability anytime, anywhere. VitalGuide empowers users with lifesaving knowledge, bridging the gap when conventional communication methods fail.
