This is an open list of web crawlers associated with AI companies and the training of LLMs to block. We encourage you to contribute to and implement this list on your own site. See information about the listed crawlers and the FAQ.
A number of these crawlers have been sourced from Dark Visitors and we appreciate the ongoing effort they put in to track these crawlers.
If you'd like to add information about a crawler to the list, please make a pull request with the bot name added to robots.txt, ai.txt, and any relevant details in table-of-bot-metrics.md to help people understand what's crawling.
A note about contributing: updates should be added/made to robots.json. A GitHub action, courtesy of Adam, will then generate the updated robots.txt and table-of-bot-metrics.md.
You can subscribe to list updates via RSS/Atom with the releases feed:

If you use Cloudflare's hard block alongside this list, you can report abusive crawlers that don't respect robots.txt here.
