ARW

OPEN STANDARD • MIT LICENSED

The semantic discovery layer for the agent-ready web

From findable to understandable.
ARW makes your site intelligible to AI agents — with structured discovery, semantic machine views, and secure actions that preserve your SEO and user experience.

WHAT ARW ADDS TO YOUR SITE

Machine views, discovery, and secure actions

Semantic machine views

.llm.md pages with stable chunk IDs reduce tokens by up to 85% and make your content interpretable by any agent.

Universal discovery via /llms.txt

A single manifest declares machine views, actions, and policies. It's the sitemap for the semantic web.

Secure actions with OAuth + Schema.org

Enable trusted agents to transact with consent, attribution, and rate limits.

Flow: Browser/Agent → /llms.txt → Machine Views → OAuth Actions → Result

BUILT FOR EVERYONE

Publishers, AI platforms, and builders

For Publishers

Trust and discoverability

Agents attribute your brand, follow your policies, and act with consent.
Result: trust and discoverability.

For AI Platforms

Lower costs, higher reliability

Stop scraping HTML. Get structured, rate-limited, consent-aware access.
Result: lower token cost and higher reliability.

For Builders

Progressive enhancement

Add /llms.txt today, .llm.md tomorrow, actions when ready.
Result: progressive enhancement, no refactors.

Frequently Asked Questions

Learn more about how ARW works and how it can benefit your site.

Why "semantic discovery"?
Because agents don't just crawl — they reason. ARW provides the structure and context they need to understand your content.
Will this hurt SEO?
No. ARW complements the human web. Machine views are alternates, not replacements.
What about Schema.org or OpenAPI?
ARW builds on them. It handles discoverability, chunking, and consent at the HTTP layer.
Who's behind this?
ARW is an open, MIT-licensed specification led by Nolan Dubeau and the community.
