Botpress is an open-source chatbot development platform designed for developers to build and manage conversational agents. It supports natural language understanding, dialogue management, and integrated machine learning modules. Users can create custom workflows and integrate them with external APIs. With Botpress, businesses can deploy chatbots on various platforms, enhancing customer engagement and automating customer service effectively.

Chat-With-CUHKSZ provides a streamlined pipeline for building a domain-specific chatbot over the CUHKSZ knowledge base. After cloning the repository, users configure their OpenAI API credentials and specify document sources, such as campus PDFs, website pages, and research papers. The tool uses LlamaIndex to preprocess and index documents, creating an efficient vectorized store. LangChain orchestrates the retrieval and prompts, delivering relevant answers in a conversational interface. The architecture supports adding custom documents, fine-tuning prompt strategies, and deploying via Streamlit or a Python server. It also integrates optional semantic search enhancements, supports logging queries for auditing, and can be extended to other universities with minimal configuration.

LangChain Chatbot for Customer Support leverages the LangChain framework and large language models to provide an intelligent conversational agent tailored for support scenarios. It integrates a vector store for storing and retrieving company-specific documents, ensuring accurate context-driven responses. The chatbot maintains multi-turn memory to handle follow-up questions naturally, and supports customizable prompt templates to align with brand tone. With built-in routines for API integration, users can connect to external systems like CRMs or knowledge bases. This open-source solution simplifies deploying a self-hosted support bot, enabling teams to reduce response times, standardize answers, and scale support operations without extensive AI expertise.
