6. Content Optimisation Features
Frase.io excels at content briefs. It analyses SERPs and gives you a list of questions that top‑ranking pages answer, suggested headings, and related topics. You can then write your content to directly answer those questions – perfect for targeting featured snippets and voice search. The optimisation score checks how well your content covers the brief.
Surfer SEO gives you a detailed dashboard with exact metrics: word count range, number of headings, keyword density, image count, and a list of related terms (NLP). It also suggests internal linking opportunities. The real‑time score updates as you write, showing you exactly how well your content matches top‑ranking pages.

Verdict: Choose Frase if your goal is to create comprehensive, question‑answering content. Choose Surfer if you need deep, data‑driven on‑page optimisation and technical SEO audits.
7. AI Writing Assistance
Frase AI generates content based on your brief. You can ask it to write paragraphs, answer specific questions, or complete entire sections. The output is coherent and matches the brief well, but it can be generic without manual editing.
Surfer AI generates full articles based on your keyword and SERP analysis. The output is well‑structured and SEO‑friendly, but it often feels formulaic and lacks personality. You will need to edit for flow and engagement.

8. Hands‑On Testing: Which Produces Better Content?
I tested both tools on the same keyword: “best AI writing tools 2026”, based on the research and methodology used in our Best AI Writing Tools in 2026 guide. Here is what I found.
Frase.io Experience
- Content brief: Frase generated an excellent brief. It listed 47 questions people ask, suggested headings (H2, H3), and showed related terms. The question discovery was especially useful for planning an FAQ section.
- Content Editor: I wrote a draft following the brief. The optimisation score highlighted which questions I had answered and which I missed. This kept me focused on covering user intent.
- AI writer: Frase AI helped me write answers to specific questions. The output was decent but required editing for a consistent voice.
Surfer SEO Experience
- SERP analysis: Surfer pulled detailed data from 20 ranking pages: average word count (2,100), number of headings (12), keyword density (1.2%), and NLP terms. Very granular.
- Content Editor: The real‑time scoring pushed me to add more headings, increase word count, and use specific related terms. The final article was very structured and SEO‑friendly but felt mechanical.
- Surfer AI: I generated a complete article. It was well‑organised but lacked personality. I had to rewrite sentences to make them engaging.
Winner for content briefs and question coverage: Frase.io.
Winner for on‑page data and technical SEO: Surfer SEO.
