Pi Web Agent is a lightweight, extensible framework for building AI chat agents on the web. It leverages Python FastAPI on the backend and a React frontend to deliver interactive conversations powered by OpenAI, Cohere, or local LLMs. Users can upload documents or connect external databases for semantic search via vector stores. A plugin architecture allows custom tools, function calls, and third-party API integrations locally, it offers full source code access, role-based prompt templates, and configurable memory storage to create customized AI assistants.

AgentChat is a developer-centric platform for building sophisticated multi-agent AI conversations. It combines a Python-based FastAPI backend and a React UI to allow users to define individual AI agents with distinct roles—such as data extractor, analyzer, and summarizer—that communicate to collaboratively complete complex tasks. Leveraging OpenAI's GPT models, AgentChat provides memory storage via Redis and supports custom tool integration for tasks like API calls, web scraping, and database querying. The platform offers real-time conversation monitoring, agent performance logs, and configurable agent pipelines. With its modular architecture, developers can extend agent capabilities by adding new tools or adjusting prompts, enabling customized automated workflows, decision-making processes, and knowledge discovery applications.
