Trip-Planner Bot: A Langchain-Powered trip planning bot

Project Introduction

This project uses the Langchain library to build a bot within a Streamlit framework, this project is a quick and dirty implementation, which serves as my first encounter with Langchain. The Trip-Planner Bot is an interactive tool for accessing geographic information, identifying points of interest, and getting travel routes with customizable waypoints and transportation modes.

Functionality Overview

The Trip-Planner Bot uses some free APIs that provide geographical information to the LLM. Below are the key functionalities offered by this application:

• Location Information Retrieval: Provides details about a given location.
• Exploration of Places of Interest: Identifies and describes nearby attractions.
• Route Planning: Generates travel routes between designated points, and supports multiple waypoints between the travel and different transportation modes.

Integration of APIs

This project harnesses the capabilities of several external APIs to furnish its core functionalities:

• OpenStreetMap API (via Geopy): This API is pivotal in obtaining accurate geocodes for each location.
• Bing Maps API: Used for creating routes between specified locations. This API supports the addition of multiple waypoints between the travel and supports different transportation modes.
• FourSquare API: Provides up-to-date information about places of interest, including concise descriptions.
• Wikipedia: Provides information to answer general questions (tool provided by Langchain)

LLM Used

The LLM used here is OpenAI's gpt-3.5-turbo, it can replaced with any other open-source LLM. To deploy the app on google-colab you can have a look at my other repo

Getting Started

To run the Trip-Planner Bot locally, you need to:

1. Clone the repository to your local machine.
2. Install necessary dependencies:

   pip install -r requirements.txt

3. Start the Streamlit application:

   streamlit run main.py

4. Navigate to the displayed URL.

Note:

Ensure you have valid API keys for OpenAI, Bing Maps, and FourSquare configured in your environment.
