What is here

Three short pages. Each states what the official page says, what it does not say, and the conditions that apply. Where two official pages differ, both are named.

Google: the controls and the report documented for AI Overviews and AI Mode.
OpenAI: the crawler settings documented for ChatGPT search and for model training.
A side-by-side that lines up the two, including what each control does not do.

Scope and limits

This is a reference, not a service description and not a result. It makes no claim that any change gets a site shown, cited or ranked. It reports what the vendors document and when we read it.

Vendors change these pages. Check the linked source before you act on a date or a setting.
