How Do You Handle Updates for AI-Generated Website Content?

I’m exploring how websites that rely on AI-generated content manage updates when underlying information changes or new information needs to be added. For example: if an AI writes an article about "Best Practices for SEO in 2023," how do you efficiently update it to "2024" incorporating new additions in a coherent way without regenerating the entire piece?

Regenerating the whole article would be inefficient as it could erase formatting, disrupt internal links. Also it probably wouldn't send the right signal to search engines where whole article changes for every update.

Are there tools/workflows to flag and update specific parts of AI content?
