Anthropic

7.6

Market-standard free keyword research tool with solid search volume and competition data; widely used and trusted by SEO/PPC professionals, but lacks advanced AI features and depth compared to paid alternatives like SEMrush or Ahrefs.

OpenAI

7.8

Google Keyword Planner is a widely used, reliable baseline for keyword discovery and search volume data, but it’s more of a classic PPC/SEO utility than an AI-first tool and lacks the depth and workflow sophistication of leading dedicated SEO platforms.

Gemini

8.5

A free, indispensable tool providing authoritative keyword data directly from Google, its algorithmic suggestions, grouping, and competition estimates make it a foundational, strong performer in AI-SEO, despite not being a full generative suite.

Grok

5.5

Google Keyword Planner is a longstanding free staple for official volume data and PPC research, but in the ai-seo category it feels dated, non-AI, and limited compared to modern alternatives like Ahrefs or SEMrush.
