How we compared the Frase.io alternatives

Frase.io is a capable SEO brief and optimization tool. It helps teams identify the topics an article should cover and build briefs comprehensive enough to rank on Google. But it is a retrofitted search tool, anchored to the SERP, with no view into how AI answer engines describe your brand.

WriteWorks is built for AI search from the ground up. It measures how 8 AI engines answer your buyers, ChatGPT, Claude, Gemini, Perplexity, Meta AI, Microsoft Copilot, Google AI Overviews, and Google AI Mode, across 23+ regions and buyer personas, tracking citation rate, share of voice, and sentiment.

Then it engineers the content that wins the citation, scoring every draft against three AI-visibility lenses, and proves the lift. Frase grades a page for one search surface; WriteWorks closes the loop across all 8 AI engines. Track it. Engineer it. Win it. Prove it.
