Cotoyogi
What is Cotoyogi?
About
Cotoyogi is a research crawler operated by Japan's Research Organization of Information and Systems that collects web content to build AI training datasets for research purposes. You can see how often Cotoyogi visits your website by setting up Dark Visitors Agent Analytics.
Expected Behavior
It's generally unclear how AI data scrapers choose which websites to crawl and how often to crawl them. They might choose to visits websites with a higher information density more frequently, depending on the type of AI models they're training. For example, it would make sense that an agent training an LLM (Large Language Model) would favor sites with a lot of regularly updating text content.

Should I Block Cotoyogi?
It's up to you. AI data scrapers usually download publicly available internet content, which is freely accessible by default. However, you might want to block them if you're concerned about attribution or how your creative work could be used in the resulting AI model.
How Do I Block Cotoyogi?
You can block Cotoyogi or limit its access by setting user agent token rules in your website's robots.txt. Set up Dark Visitors Agent Analytics to check whether it's actually following them.
# In your robots.txt ...

⚠️ Manual Robots.txt Editing Is Not Scalable
New agents are created every day. We recommend setting up Dark Visitors Automatic Robots.txt if you want to block all agents of this type.
