Which AI is best for SEO?

For writing, outlining, and general SEO work I use Claude. It handles long context better and the writing reads less generic than the alternatives. ChatGPT is fine too, especially with custom instructions.

For keyword research and competitive analysis I still rely on actual SEO tools (Ahrefs, Search Console, DataForSEO). No AI yet replaces real search data.

The right setup is usually one general-purpose AI plus the SEO tools you'd use anyway, glued together by your own workflow. The "best AI" question matters less than how well you use whichever one you pick.
