What is NLWeb?
Building conversational interfaces for websites or making your content accessible to AI agents can feel like navigating a complex maze. The challenge lies in transforming diverse web content into a format that natural language systems can easily understand and interact with.
NLWeb offers a foundational solution to this problem. It provides a collection of open protocols and associated open-source tools designed to make it straightforward for websites to offer natural language interfaces. By leveraging widely-used semantic standards like Schema.org and related formats, NLWeb helps bridge the gap between traditional web content and the emerging "AI Web," enabling seamless communication between both humans and intelligent agents.
Key Capabilities
🤝 Define a Simple Protocol: NLWeb includes a straightforward protocol for natural language interaction, simplifying how external systems query your site's content.
🧱 Leverage Existing Semantics (Schema.org): It utilizes JSON and the widely adopted Schema.org vocabulary for structured, machine-readable responses to natural language queries, building upon existing web standards.
🛠️ Implement with Open Source Tools: Get started quickly with provided open-source tools, including core services, connectors for popular LLMs and vector databases, and data ingestion tools for formats like Schema.org JSON-LD and RSS.
✨ Remain Platform & Tech Agnostic: NLWeb is designed to work seamlessly across various operating systems (Windows, MacOS, Linux), vector databases (Qdrant, Snowflake, Milvus, Azure AI Search, etc.), and Large Language Models (OAI, Deepseek, Gemini, Anthropic, etc.), offering flexibility in your technical stack.
Practical Applications
NLWeb provides the building blocks to enable new forms of interaction with your website's content:
Make Product Catalogs Queryable: Transform a standard e-commerce product listing into a conversational endpoint. A user could ask, "Show me red running shoes under $100," and an NLWeb-powered interface could return structured results pulled directly from your site's existing Schema.org markup or product data, bypassing traditional faceted search.
Unlock Recipe & Content Search: For sites rich in structured content like recipes, articles, or documentation, NLWeb allows users or agents to query using natural language. An agent could ask, "Find vegan recipes with less than 5 ingredients," and receive a structured, machine-readable list of relevant recipes, enabling integration into other applications or conversational assistants.
Facilitate Agent-to-Agent Communication: Build endpoints that allow AI agents to directly query your site's structured data for automated tasks. An agent could fetch event details, compare service features based on documented attributes, or summarize reviews by querying an NLWeb endpoint, creating a more interconnected and intelligent web.
NLWeb provides the open foundation needed to make your website's content easily accessible and queryable via natural language for both humans and AI agents. By leveraging existing web standards like Schema.org and offering practical, agnostic tools, it helps you build the necessary endpoints to participate in the emerging AI Web, fostering a more connected and intelligent online environment.
