Question & Answer System for E-Learning

• This is an end-to-end LLM project based on Google Generative AI and Langchain. In this project I built a Q&A system based on a data from an e-learning company called codebasics (website: codebasics.io). Codebasics sells data related courses and bootcamps. They have thousands of learners who uses discord server or email to ask questions. This system will provide a streamlit based user interface for students where they can ask questions and get answers.

DEMO

Project Highlights

• Use a real CSV file of FAQs that Codebasics company(E-Learning platform) is using right now.
• Their human staff will use this file to assist their course learners.
• We will build an LLM based question and answer system that can reduce the workload of their human staff.
• Students should be able to use this system to ask questions directly and get answers within seconds
