The Content Kit, from $99 a month, adds an AI Content Helper and grader, and custom prompt packages let you track your own branded prompts. Every plan includes API access and an MCP server for connecting Ahrefs data to AI assistants.

Ahrefs suits SEO professionals, agencies and in-house teams who rely on link and competitor data.
