# Chatformers

⚡ Chatformers is a Python package designed to simplify the development of chatbot applications that use Large Language Models (LLMs). It offers automatic chat history management using a local vector database (ChromaDB, Qdrant or Pgvector), ensuring efficient context retrieval for ongoing conversations.

## Why Choose chatformers?
1. Effortless History Management: No need to manage extensive chat history manually; the package automatically handles it.
2. Simple Integration: Build a chatbot with just a few lines of code.
3. Full Customization: Maintain complete control over your data and conversations.
4. Framework Compatibility: Easily integrate with any existing framework or codebase.


## Key Features
1. Easy Chatbot Creation: Set up a chatbot with minimal code.
2. Automated History Management: Automatically stores and fetches chat history for context-aware conversations.

## How It Works
1. Project Setup: Create a basic project structure.
2. Automatic Storage: Chatformers stores your conversations (user inputs and AI outputs) in VectorDB.
3. Contextual Conversations: The chatbot fetches relevant chat history whenever you engage with the LLM.


## Prerequisites-

1. Python: Ensure Python is installed on your system.
2. GenAI Knowledge: Familiarity with Generative AI models.

## Example Usage-
