Microsoft introduces NLWeb, an open-source project that enables websites to integrate AI-powered chatbots and natural language interfaces, potentially revolutionizing web interactions and paving the way for an 'agentic web'.

Microsoft Introduces NLWeb at Build 2025

Microsoft has unveiled NLWeb, an innovative open-source project aimed at revolutionizing web interactions through AI integration. Announced at the Build 2025 conference, NLWeb promises to transform ordinary websites into AI-powered platforms, enabling natural language interfaces and chatbot functionalities with minimal coding effort 12.

What is NLWeb?

NLWeb, short for Natural Language Web, is Microsoft's latest initiative to simplify the creation of AI-powered chatbots on websites. The project allows developers to implement a conversational interface using just a few lines of code, their preferred AI model, and their own data 1. This technology-agnostic framework supports all major operating systems and is compatible with various AI models and vector databases 4.

Key Features and Capabilities

  1. Easy Integration: NLWeb enables websites to provide a "conversational interface" - typically a text field and submission button - for users to interact with AI-powered features 1.

  2. Model Context Protocol (MCP) Support: Websites built using NLWeb can optionally make their content discoverable and accessible to AI platforms that support MCP, Anthropic's standard for connecting AI models to data sources 12.

  3. Semantic Interaction: Microsoft envisions NLWeb playing a role similar to HTML for the "agentic web," allowing users to interact directly with web content in a rich, semantic manner 1.

  4. Versatile Applications: The technology can be applied across various sectors. For instance, a retailer could use NLWeb to create a chatbot for personalized clothing recommendations, while a cooking site could build a bot suggesting complementary dishes 13.

Industry Impact and Adoption

Several prominent websites have already deployed NLWeb, including Tripadvisor, Shopify, and Eventbrite. Contributors to the project include organizations such as Chicago Public Media, Common Sense Media, Inception Labs, O'Reilly Media, and Snowflake Inc 25.

Technical Aspects

NLWeb utilizes semistructured data already published by websites, such as Schema.org and RSS information, combining these with Large Language Models (LLMs) to create a natural language interface accessible to both humans and AI agents 2. The project includes a lightweight codebase controlling core services for handling natural language queries, along with extensive documentation for customization and extension 2.

Future Implications

Microsoft believes that NLWeb could significantly impact the future of web interactions:

  1. Agentic Web: By supporting the Model Context Protocol, NLWeb-enabled websites could become part of an "agentic web," where AI agents can easily access and interact with web content 4.

  2. Enhanced User Experience: The natural language interface could provide more intuitive interactions with web content, potentially improving user engagement and satisfaction 3.

  3. AI Traffic: Microsoft is building NLWeb with an eye toward future AI agents, which it believes will soon make up a significant amount of internet traffic 2.

Development and Origins

NLWeb was conceived and developed by Microsoft Technical Fellow R.V. Guha, creator of widely used web standards such as RSS, RDF, and Schema.org 2. While Microsoft hasn't confirmed, there are speculations that NLWeb may have its origins in technology from ChatGPT maker OpenAI, Microsoft's close collaborator 13.

As NLWeb continues to evolve, it has the potential to reshape how users and AI agents interact with web content, possibly ushering in a new era of intelligent, conversational web experiences.
