The /ai Standard

The web was built for human browsers.
AI agents are a fundamentally different client.

Every time an AI agent visits your site, it processes 10,000–50,000 tokens — HTML, scripts, styles, ads — just to find the few hundred tokens it actually needed./ai ends that.

To implement

Works on every website

Install the MCP server once. Your AI agent auto-discovers what any site can do — even if the site hasn't implemented /ai yet.

1

Direct check

Agent fetches site.com/ai directly. If the site implements the standard, done — ~800 tokens, 100% accurate.

2

Community registry

No /ai? Check if another agent already generated a spec. 100+ popular services are pre-indexed and growing.

3

Agent generates

Still nothing? Your agent analyzes the site and creates the spec. It's saved to the registry — every future agent benefits.

Your AI agent pays the generation cost once. The community shares the result forever. Learn more →

The web got better when everyone added robots.txt.
It's happening again.

Every service that implements /ai reduces wasted tokens across the entire AI ecosystem — not for one company, but for everyone building with AI. The spec is open. Implementation takes 10 minutes.
