Writer Framework

Writer Framework is an open-source Python framework designed for building AI applications fully integrated with the Writer platform. It allows developers to create user interfaces through a visual editor while writing backend logic in Python, supporting applications such as knowledge assistants, campaign automation, and RFP workflows. The framework employs a state-driven architecture with reactive state references and event handlers, enabling clear separation between UI and business logic. It integrates with Writer's large language models, retrieval-augmented generation tools, AI guardrails, and APIs for text generation, chat, and knowledge graph management. Deployment and app lifecycle management are facilitated through command-line interface commands. Writer Framework leverages the Python ecosystem with Poetry for dependency management, promoting clean and testable code.
