Anthropic

7.6

Strong competitor in AI-SEO writing tools with solid feature parity to market leaders; widely used by content teams, though lacks the brand dominance and ecosystem depth of top alternatives like Jasper or Copy.ai.

OpenAI

7.0

A solid, widely used SEO writing assistant with genuinely useful on-page guidance and checks, but it’s more of a workflow aid than a category-defining AI writer, and its AI generation capabilities are not best-in-class versus top competitors.

Gemini

8.5

SEMrush Writing Assistant is a robust and widely adopted tool leveraging SEMrush's vast SEO data to provide strong real-time optimization guidance, making it a powerful assistant for content creators.

Grok

7.3

SEMrush's established SEO platform gives its Writing Assistant strong real-world adoption and keyword integration, placing it as a capable alternative rather than the defining leader in the ai-seo category.
