I mainly use AI for the boring and time consuming SEO tasks, and leave the more complex things for humans.
ChatGPT – keyword research, content outlines, topical maps, meta titles and competitor analysis.
Claude – long form content, content briefs and handling large data.
Perplexity – quick SERP/competitor research and finding sources.
I also use AI with Screaming Frog and Ahrefs exports to find things like missing metadata, keyword cannibalization, weak pages and backlink issues.
For me AI works better as an SEO assistant, not a full replacement. I still double check the data and make the final SEO decisions myself.
