LLMs.txt
Your Help Center now includes an automatically generated LLMs.txt file. This makes it easier for large language models like ChatGPT or Claude to index your Help Center content. As a result, your support articles can be surfaced when users ask questions in these tools.
You do not need to take any action. Every Plain Help Center now has an LLMs.txt file by default and we will be kept up to date automatically as you add or update articles.
