Best keyword research tool — according to AI
We asked AI assistants 6 questions a real buyer would ask about keyword research tools — “what's the best?”, “what would you recommend for a small business?”, “what's a good affordable option?” — and counted which products the AI actually named. This is what the models recommend today (last checked September 7, 2026).
