At Build 2025, Microsoft launched NLWeb, a new open-source project designed to revolutionize the internet. Short for Natural Language Web, NLWeb makes it possible for websites to answer user questions in plain language—no keyword stuffing, no forms, no search boxes. Just ask, and the site responds like an AI assistant.
With this, Microsoft isn’t just building another chatbot. It’s laying the foundation for a new kind of internet—one where every website behaves like an app, powered by artificial intelligence.
Imagine you’re on a travel website. Instead of clicking through 10 pages to find hotel prices and refund policies, you just ask:
“What’s the cancellation policy for Goa hotels in June?”
The site responds instantly, like you’re chatting with a human—or better yet, Copilot.
With Microsoft NLWeb, that’s the future. You talk. Websites answer.
This isn’t science fiction. It’s the next step in how we use the web—and it’s being built now.
NLWeb is like HTML for the AI era
In a blog post, Microsoft said NLWeb could become “what HTML was for web creation”—but for AI-powered interfaces. Just as HTML opened up website building to the world, NLWeb could do the same for AI tools on the internet.
The company calls it “the fastest and easiest way to turn your website into an AI app.”
So yes, Microsoft isn’t just dreaming. It’s pushing for a future where every site can host a smart, responsive, human-like AI assistant right on the homepage.

From browsing to doing: AI agents take over the web
Here’s where it gets wild. Every NLWeb-enabled website will also act as a Model Context Protocol (MCP) server. That’s a new universal standard—developed by Anthropic—for letting AI systems connect to external data sources.
This means AI agents can talk to websites, understand them, crawl them, and act on your behalf.
Not just read content.
But chat with customer service, negotiate a discount, process a return, or verify your warranty—without you lifting a finger.
Built for everyone, not just Microsoft
Microsoft made a point to say that NLWeb is technology-agnostic. It’s open-source. It works with any OS, AI model, and vector database.
In other words: it’s not locked into Microsoft’s walled garden. They want this to work everywhere—a rare flex in today’s world of platform wars.
Also worth noting: NLWeb was developed by RV Guha, Microsoft’s new Corporate VP and Technical Fellow. Guha’s name may not be household-famous, but he’s known in the tech world for laying the groundwork for the semantic web. In short, he’s not here to build toys. He’s here to change the game.
Honestly? There isn’t an obvious one yet. But as websites start talking back, expect a few awkward conversations—especially with AI agents trying to be your shopping BFF.
Still, this isn’t just another AI gimmick. It’s Microsoft laying down a new internet protocol. One that might outlive all of us.
