> So literally every article will be labeled as AI assisted and it will be meaningless.

The web novel website RoyalRoad has two different tags that stories can/should add: AI-Assisted and AI-Generated.

Their policy: https://www.royalroad.com/blog/57/royal-road-ai-text-policy

> In this policy, we are going to separate the use of AI for text, into 3 categories: General Assistive Technologies, AI-Assisted, AI-Generated

The first category does not require tagging the story, only the other two do.

> The new tags are as such:

> AI-Assisted: The author has used an AI tool for editing or proofreading. The story thus reflects the author’s creativity and structure, but it may use the AI’s voice and tone. There may be some negligible amount of snippets generated by AI.

> AI-Generated: The story was generated using an AI tool; the author prompted and directed the process, and edited the result.
