Microsoft introduced a new open project dubbed NLWeb at its Build 2025 conference on Monday. Short for Natural Language Web, the NLWeb project aims to build an interface to websites that artificial intelligence (AI) models. With AI capabilities, these websites will then natural language queries by s and provide answers for those queries. The Redmond-based tech giant says that NLWeb could have a similar effect in building AI-enabled websites, like the introduction of HTML did for website creation.

Microsoft Says NLWeb Will Turn Websites Into AI Apps j6y5g

In a newsroom post, the tech giant announced its new open project dubbed NLWeb. The technology is Microsoft's vision for future websites, where every web page comes with AI capabilities to handle natural language queries. Essentially, this system will replace traditional search boxes on websites with an AI-powered chatbot interface.

Introducing the project, the company said NLWeb is “the fastest and easiest way to effectively turn your website into an AI app, allowing s to query the contents of the site by directly using natural language, just like with an AI assistant or Copilot.” However, the scope of NLWeb is not just limited to creating AI chatbots on web pages.

Microsoft Releases an Open-Source AI Agent That Can Complete Tasks Online

The company said every such AI-powered website will also act as a Model Context Protocol (M) server. M was developed by Anthropic as a universal, open standard for how AI systems connect to external data hubs. By ing the protocol, each NLWeb website will also make its content accessible and crawlable to AI agents and other participants in the M ecosystem.

This will create a new structure for websites where the entire network of NLWeb-enabled websites will be readily available to AI agents for data extraction and to let them perform actions. “Ultimately, we believe NLWeb can play a similar role to HTML in the emerging agentic web,” the company said.

With NLWeb, Microsoft believes an AI agent-friendly Internet can be created, making the creation and functioning of browser-based agentic tools more common and widely prevalent. In such a system, AI agents can potentially complete much more complex tasks than just purchasing a product online. They can, for example, talk to a brand's sales agent, negotiate discounts, warranties, and handle returns autonomously.

Microsoft highlights that the open project is technology agnostic and s all major operating systems, AI models, and vector databases. Notably, NLWeb was coined and developed by RV Guha, the company's recently ed Corporate Vice President and Technical Fellow.
