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 an open-source AI Agent management platform that leverages OpenAI's GPT models to run versatile conversational agents. It provides a React front-end for interactive chat sessions, a Node.js back-end for API routing, and a plugin system for extending agent capabilities. Agents can be configured with role-based prompts, persistent memory storage, and pre-defined workflows to automate tasks such as summarization, scheduling, data extraction, and notifications. Users can create multiple agent instances, assign custom names, and switch between them in real-time. The system supports secure API key management, and developers can build or integrate new data connectors, knowledge bases, and third-party services to enrich agent interactions.
