Free tools for being found by machines.
Assistants read the web before most people do, and they are unforgiving about it: a page whose words only appear after JavaScript runs is a blank page to them. These say whether yours is. No signup and no email.
Five of them keep nothing but the domain and the grade, for the feed of what has been checked. The AI-readiness check is the exception: it stores the whole result and publishes it at a permanent public page, /scan/yourdomain, which search engines can index.
We built them because this site depends on the same thing. We count how often named crawlers read each of our boards, so these are the checks we run on ourselves.
- Can AI read your site?Six checks and a grade, published at its own public page. The one to run first if you only run one.
- Are you blocking AI crawlers?Which of GPTBot, ClaudeBot, PerplexityBot and the rest your robots.txt lets in.
- llms.txt generatorCheck whether you publish one, and get a starting file written from your own page.
- Is your content in the HTML?Assistants do not wait for your app to boot. This says what they see before it does.
- What your link looks likeThe title, description and image every share of your site is using right now.
- Structured data checkWhich JSON-LD types your page declares, and what is missing.
