Pillar is a comprehensive AI agent framework designed to simplify the development and deployment of intelligent multi-step workflows. It features a modular architecture with planners for task decomposition, memory stores for context retention, and executors that perform actions via external APIs or custom code. Developers can define agent pipelines in YAML or JSON, integrate any LLM provider, and extend functionality through custom plugins. Pillar handles asynchronous execution and context management out of the box, reducing boilerplate code and accelerating time-to-market for AI-driven applications such as chatbots, data analysis assistants, and automated business processes.

Serena is designed to automate complex workflows through autonomous planning and execution. It interacts with web search engines, databases, and APIs to gather information, summarizes results, and carries out tasks according to user-defined goals. Built as a Python library, Serena maintains stateful memory across sessions, dynamically loads plugins for extended capabilities, and uses large language models to generate structured plans. Developers can customize tool integrations for code execution, file management, and analytics, making Serena a versatile framework for research, data processing, content generation, and beyond.
