Open for agents

Make your business agent ready.

AI assistants now compare, book and buy for people. Sill helps them find you, act on your rules, and shows you what they did.

See what AI assistants find on your site, and what they miss.

Agents act. You decide.

Drag your line. Anything that moves more money than that waits for your OK, by email or Slack.

      FAQ

      Fair questions.

      More answers in the docs →

      Does it work on my platform?

      Yes. WordPress and WooCommerce use the plugin, any site behind Cloudflare uses the Worker, Shopify uses the app, and any other site takes one script tag.

      Do you touch my money?

      No. Your payment provider moves it; Sill decides what’s allowed and signs the record.

      What does the free check look at?

      Only public files: robots.txt, llms.txt, your agent card, structured data, sitemap and a few more.

      What happens when an agent wants something big?

      It waits. You get an email (and a Slack message, if you connect it), then approve or decline from the dashboard.

      Will this block real customers or helpful assistants?

      No. People browse as they always have; your rules apply to what agents try to do, not to page visits.

      Can I check your records myself?

      Yes. Every record is signed with our published key, and sill.so/verify checks a bundle in your browser without uploading it.
