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.
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.
Thank you to Glyn for pushing me to set this up after I posted about blocking these crawlers.
