Microsoft‘s new NLWeb protocol marks a pivotal shift in how websites will interact with AI, offering enterprises a standardized way to make their digital content accessible to AI systems. Similar to how RSS transformed content syndication in the early 2000s, NLWeb creates a framework for websites to become AI-ready through natural language interfaces. This protocol represents a significant advancement in the evolution of the web, potentially changing how users and AI agents alike access and interact with online information.
The big picture: Microsoft has launched NLWeb, an open-source protocol designed to AI-enable websites by creating natural language interfaces that work for both human users and AI agents.
- The protocol was conceived by RV Guha, who previously helped create RSS, RDF, and schema.org, linking NLWeb to earlier web standardization efforts.
- NLWeb builds upon existing protocols rather than competing with them, functioning as a Model Control Protocol server while utilizing familiar structured data formats like RSS.
How it works: NLWeb transforms websites into AI applications through a four-step process that leverages existing data structures and enhances them with artificial intelligence.
- The system begins by using structured data already published by websites, including markup and RSS feeds.
- Special tools process this data into vector databases, enabling efficient semantic search capabilities.
- Large language models enhance the stored data with external knowledge and contextual understanding.
- The final output is a universal natural language interface serving both human users and AI agents.
Early adoption: Several major digital platforms have already implemented NLWeb, signaling growing interest in AI-enabling web content.
- Early adopters include Chicago Public Media, Allrecipes, Eventbrite, Hearst (Delish), O’Reilly Media, Tripadvisor and Shopify.
- Microsoft CTO Kevin Scott described NLWeb as “a little bit like HTML for the agentic web,” highlighting its potential for standardization.
Market implications: Experts suggest a measured approach to NLWeb implementation, with timeline expectations varying by industry.
- Constellation Research projects substantial adoption will take 2-3 years to materialize.
- Companies with specific use cases are positioned to benefit from early pilot programs.
- Highly regulated sectors like insurance, banking, and healthcare are advised to proceed with caution.
Why this matters: For enterprise AI leaders, NLWeb represents a significant opportunity to transform websites into AI-ready platforms, potentially becoming as essential to the AI era as RSS was to the early web.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment
The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
