NLWeb: The Future of Conversational Web Interaction

Remember when HTML turned static pages into interactive, styled documents? Now, Microsoft’s NLWeb is set to revolutionize web interaction again. Announced at Build 2025 by CEO Satya Nadella and CTO Kevin Scott, NLWeb is described as the “HTML for chat.” It transforms every website into a natural-language endpoint, allowing both humans and AI agents to query content directly.

What’s New with NLWeb?

NLWeb enables websites to become conversational hubs. Instead of searching with keywords, users can ask questions naturally, and get instant, relevant answers. This leap means websites don’t just display information—they engage in meaningful dialogue. Moreover, NLWeb instances act as Model Context Protocol (MCP) servers, exposing content to AI assistants and enabling seamless Agent-to-Agent (A2A) workflows across different sites.

“NLWeb is the next leap for conversation—the ‘HTML for chat’—turning every site into a natural-language endpoint.” – Microsoft

Major Updates and Early Adopters

Several pioneers are already showcasing NLWeb’s power through real-world use cases:

  • Tripadvisor: Plans entire family trips conversationally, from destination ideas to full itineraries.
  • Qdrant: Offers lightning-fast, intent-aware search using its vector database technology.
  • O’Reilly Media: Lets users query technical content like chatting with an expert.
  • Eventbrite: Finds events based on user intent, not just keywords.
  • Delish (Hearst): Matches recipes instantly based on pantry items and preferences.

Other collaborators include Chicago Public Media, Shopify, Snowflake, and more, all contributing to an open, agentic web foundation.

Why This Matters for Developers and Tech Enthusiasts

NLWeb isn’t just a feature; it’s a protocol-based paradigm shift. Developers can build conversational endpoints that AI agents and users query naturally. This opens doors for richer, more intuitive user experiences and smarter AI integrations. Plus, NLWeb’s GitHub repository is now live, inviting the community to start building and experimenting.

“Together, these collaborators are laying the protocol-based foundation for an open, agentic web—where sites don’t just display content, they converse.” – Microsoft
