SEO Skill vs ChatSEO

ChatSEO is a paid SEO chat app that runs its own AI agents on your Search Console data and DataForSEO market data, with a hosted MCP server on its Pro plan and above. SEO Skill gives your agent your own Search Console, Google Analytics and keyword data for free, with nothing to install.

Get started free

Run it in a terminal, then sign in with Google.

Or run it on your machine

Installs the CLI, signs you in and adds the skill to your agents. Site crawls and Bing data run this way, on your own machine. A crawl fetches many pages, and Bing blocks our hosted server.
