How To Use

Need help?

1. Your domain

Domain that will host the file

Used in each entry’s identifier (urn:air:domain:…) and in the file location.

2. What do you want to list?

Pick what you have. Most websites only need the llms.txt option.

3. Your ard.json

Where to put it

Upload the file to https://example.com/.well-known/ard.json. Optionally add this line to robots.txt:

How to use the ARD Manifest Generator

Enter your domain, for example www.yourdomain.com.
Choose what to list. Most websites only need My llms.txt file: one click fills in the name, link and example questions from your domain. If you run an MCP server or AI agent, choose that option and add the link to its card.
Check the example questions. Two to five plain-language questions help registries match your entry to what agents search for.
Fix anything flagged on the right. Errors would fail the Lighthouse ard.json audit; suggestions are best practice.
Copy or download your ard.json.

Need more control? Open Advanced options on any entry to change its identifier, type, inline card JSON or capabilities. Already have a manifest? Use Import it to load and edit an existing ard.json or ai-catalog.json.

What to do with your ard.json

Upload it to https://yourdomain.com/.well-known/ard.json. On WordPress, use your host’s file manager or SFTP, since WordPress doesn’t manage the .well-known folder.
Optionally add Agentmap: https://yourdomain.com/.well-known/ard.json to your robots.txt.
Run Lighthouse in Chrome DevTools with the Agentic Browsing category and check the ard.json audit passes. Learn more in our guide to Agentic Browsing audits in Lighthouse.

Frequently asked questions

What is an ard.json file?

An ard.json file is an Agentic Resource Discovery manifest: a JSON file at /.well-known/ard.json that lists the tools, agents and skills AI agents can use from your organization. Registries crawl these files so agents can find, verify and connect to your capabilities.

Is this ARD generator free?

Yes. The generator is free and needs no sign-up. It runs entirely in your browser, so the details you enter are not sent to or stored by Netsurge. Copy the JSON or download the ard.json file when you’re done.

Will the generated file pass the Lighthouse and Google PageSpeed Insights’ ard.json audit?

The generator checks the same entry rules Lighthouse uses for ARD v0.91: required fields, the urn:air identifier format, a valid media type, and exactly one of url or data. Lighthouse also fails the audit if the file or an advertised location doesn’t load, so upload it correctly and re-test.

Does my website need an ard.json file?

Only if you publish capabilities AI agents can call, such as an MCP server, A2A agent, API or agent skills. Ordinary business websites can skip it; Lighthouse then marks the audit not applicable. ARD does not affect Google rankings.

Can I edit an existing ai-catalog.json file?

Yes. Use Import existing ard.json, paste your ai-catalog.json or ard.json, and the generator loads every entry for editing. Then download the result as ard.json and upload it to /.well-known/ard.json, the location used since ARD v0.91.
