Project Overview

RasoiGuru is your ultimate cooking assistant chatbot, designed to offer detailed cooking instructions, ingredient substitutions, and personalized culinary tips to elevate your kitchen skills.

It uses Retrieval-Augmented Generation (RAG) from multiple data sources like professional cookbook PDFs and Wikipedia. This combination ensures that the chatbot provides accurate and comprehensive culinary information.

The application is converted to an API using FastAPI, allowing seamless integration and access to RasoiGuru's capabilities through a user-friendly interface. It has robust logging and exception handling mechanisms to ensure smooth operation and error detection. Additionally, a setup module is implemented to streamline the installation process and manage dependencies effectively.

Deployed on Amazon Web Services (AWS), RasoiGuru offers easy access and utilization for users. AWS also ensures scalability, allowing the application to handle varying user loads seamlessly.
