Content teams often ask how AI writing tools and SERP grading tools fit alongside dedicated Generative Engine Optimization (GEO) platforms.
Frase is a widely used content editing platform designed to accelerate article research, outline creation, and Google SERP term grading. Visiby, in contrast, is an AI citation tracking and intelligence platform that measures brand presence inside conversational engines like ChatGPT, Perplexity, and Google AI Overviews.
This comparison examines how their workflows differ, analyzes their pricing models, and explains how to choose the right tool for your search strategy. Run your free Visiby baseline report to measure your AI citation rates without a credit card.
What Visiby does: measure, then fix
Traditional content creation tools focus on keyword inclusion to satisfy Google's search algorithms. However, generative search engines operate on Retrieval-Augmented Generation (RAG), synthesizing answers from a select group of authoritative passages rather than ranking long-form blog posts.
Visiby is engineered around this citation mechanic. Every weekly run samples your target buyer prompts across ChatGPT, Perplexity, and Google AI Overviews, reporting each platform separately and pinpointing the exact passages cited.
Visiby's Action Plan tab prioritizes these citation gaps by estimated business value. On the Pro tier, the Brand Entity tab evaluates how AI engines perceive your company, while Competitor Intelligence reveals which competitor domains hold target citations.
Visiby then produces finished deliverables. It writes structured content briefs and complete articles designed around winning citation formats. You publish the content, and Visiby measures the citation impact on the next weekly run.

Where Frase fits
Frase is an effective, user-friendly content creation and on-page grading tool. Sourced from its platform documentation, Frase helps copywriters and content marketers accelerate the drafting process.
It scrapes the top 20 Google results for a target keyword, summarizes key discussion points, and calculates a real-time Topic Score based on entity mentions and term density. It also provides an in-browser document editor, automated outline generators, and AI writing assistance.
If your primary objective is helping staff writers quickly produce traditional blog content structured for Google's standard blue-link search results, Frase provides an accessible, proven workflow.
Pricing, side by side: per-document vs flat-rate
Frase charges based on the number of document grading briefs created per month, with AI writing features requiring a supplemental monthly add-on. Visiby provides flat-rate pricing based on prompt tracking volume, with full reporting and deliverables included on every tier.

| Entry tier | $15/mo Solo: 4 document briefs/mo (1 user) | $99/mo Starter: 50 prompts, 3 engines (ChatGPT, AIO, Perplexity), weekly refresh, Action Plan, finished deliverables |

| In-browser editor | Full document editor with real-time Topic Score | Delivers finished markdown and briefs for deployment |
| Crawler telemetry | Focuses on search index content | Monitors GPTBot, ClaudeBot, PerplexityBot, and Google-Extended |
| Pricing metric | Metered per document brief per month | Flat per plan with zero per-engine add-ons |
What our benchmark proves
Writing content solely for traditional Google rankings does not guarantee presence in conversational AI answers. In our 172-prompt benchmark, source distribution varied significantly across platforms:
| Source domain | ChatGPT | Perplexity | Google AI Overviews |
|---|---|---|---|
| 45% (78/172) | 0% (0/172) | 29% (50/172) | |
| YouTube | 0.6% (1/172) | 66% (114/172) | 54% (92/172) |
| Semrush | 7% (12/172) | 24% (42/172) | 16% (27/172) |
Traditional SEO tools focus on matching keywords found on page one of Google. However, generative engines cite content based on entity clarity, Information Gain, and concise passage structure. Writing for AI engines requires monitoring where citations actually occur rather than merely matching word counts.
