Clearscope (Marketing) and Frase (Writing) come from different corners of the market, so this usually comes down to which job you're actually hiring a tool for, not a head-to-head on the same task.
Choose Clearscope if…
Best for enterprise content teams and agencies producing large volumes of articles that need a consistent SEO grade, and its edge is the most accurate NLP-based content grading available, with a seamless Google Docs plugin. The gold standard for enterprise SEO scoring, now paired with an AI drafting workflow, though the price still keeps it out of reach for solo use. Lean toward Frase instead if pulls the top 20 search results for a keyword and turns their structure into an optimized content brief automatically matters more for your use case.
Choose Frase if…
Best for content teams who want a research brief built from what's already ranking, before writing begins, and its edge is pulls the top 20 search results for a keyword and turns their structure into an optimized content brief automatically. Excellent for the research phase specifically, its own AI writer is a secondary feature at best. Lean toward Clearscope instead if the most accurate NLP-based content grading available, with a seamless Google Docs plugin matters more for your use case.
