What changed —
and when?
RobotCheck checks websites against a living rule catalog. Here you can see every version: which rule was added, what changed, and which source triggered it.
Current version
v0.4.0
11 rules active
🔄
Weekly update
Every Monday the official sources of AI providers are checked. A new version is created only when something genuinely changes — no updates for the sake of updates.
📌
Version stamp
Every analysis report shows which rule version it was run against. Older reports remain traceable — even if the rules have changed since.
🌐
Sources
Anthropic, OpenAI, Google and llmstxt.org — rules come directly from the official documentation of AI providers.
