Does AI Overview Use ChatGPT?

No, Google's AI Overview does not use ChatGPT in any way. It runs entirely on Google's own Gemini family of AI models, built and trained by Google, with no OpenAI technology involved.

The confusion is understandable since both tools do a similar job, reading web content and generating a written summary, and both launched into wide public use around the same period.

They remain separate systems built by competing companies, each with its own crawler, its own index, and its own rules for what gets cited and how.

Optimizing for both separately is exactly what AI SEO tool is built to handle.
