Microsoft has introduced NLWeb, a new open-source project designed to bring natural language-powered interfaces directly to the web. Positioned as a foundational layer for the emerging agentic web, NLWeb enables developers to embed conversational experiences into existing websites using a simple, HTML-like declarative syntax.
With NLWeb, developers can easily define AI agents and input/output fields that handle natural language queries, summarize content, fetch APIs, or guide users through multi-step tasks. The project includes runtime support for model orchestration, context handling, and memory persistence.
Microsoft says NLWeb aims to be the 'HTML of the agentic web,' offering developers a standard way to layer generative AI functionality onto any static or dynamic web property. Use cases range from customer support chat to intelligent documentation search, personalized onboarding, and task automation.
The framework supports integration with Microsoft’s Copilot stack, Azure AI services, and open LLM endpoints, and includes security and governance tools for enterprise readiness.
As the industry trends toward embedded agents and assistant-style workflows, NLWeb positions Microsoft at the forefront of the conversational UI standardization movement—paving the way for a web where natural language is a native mode of interaction.
