LangGraph Learn combines a visual programming interface with an underlying Python SDK to help users build complex AI agent workflows as directed graphs. Each node represents a functional component such as prompt templates, model calls, conditional logic, or data processing. Users can connect nodes to define execution order, configure node properties through the GUI, and execute the pipeline step-by-step or in full. Real-time logging and debugging panels display intermediate outputs, while built-in templates accelerate common patterns like question-answering, summarization, or knowledge retrieval. Graphs can be exported as standalone Python scripts for production deployment. LangGraph Learn is ideal for education, rapid prototyping, and collaborative development of AI agents without extensive code.

LangGraphJS API provides a programmatic interface to design AI agent workflows using directed graphs. Each node in the graph represents an LLM call, decision logic, or data transformation. Developers can chain nodes, handle branching logic, and manage asynchronous execution seamlessly. With TypeScript definitions and built-in integrations for popular LLM providers, it streamlines development of conversational agents, data extraction pipelines, and complex multi-step processes without boilerplate code.
