Build an AI ChatBot with Gradio, Gemini, and LangChain V1

Level: Real World

Your task for today is to create a fully functional AI chatbot web application with conversation memory using just 67 lines of code! This chatbot keeps track of your entire conversation, remembering what you’ve said previously so you can have natural, flowing discussions just like talking to a real person. The complete working code is provided in the solution file.

Project Task

Create an AI chatbot web app that:

• Uses Gradio to create an interactive web interface

• Integrates Google’s Gemini 2.5 Flash AI model via LangChain

• Maintains conversation history so the bot remembers previous messages

• Allows continuous multi-turn conversations with context awareness

• Converts chat history between Gradio and LangChain message formats

• Loads API credentials securely from environment variables

• Includes example prompts to get users started

• Runs as a complete web application in the browser

This project gives you hands-on practice with AI integration, conversation management, web interfaces, and state handling — essential skills for building intelligent conversational applications.
