Frase - briefs and content
Frase builds content briefs from search results and helps you write with AI. Per the pricing page, the cheapest plan costs $39 a month, and there's a 7-day trial with no card required.
Who it's for: people writing in English who want fast briefs.
Downsides: fewer data features than the all-in-one suites, so you'll still need a separate tool for keywords and links.
Peec AI - AI visibility only
Peec AI is a GEO-only tool: it tracks how often and in what context AI models mention your brand and your competitors. Its pricing page lists Starter, Pro, Advanced and Enterprise plans, but it didn't show me any amounts in October 2026.
Who it's for: brands that treat ChatGPT as a separate customer acquisition channel.
Downsides: it won't replace an SEO tool, and prices aren't publicly visible.
Visibility in ChatGPT, aka GEO
GEO (Generative Engine Optimization) is about getting ChatGPT, Gemini, Perplexity and AI Overviews to cite your site or recommend your brand. What that means in practice:
- You track prompts, not keywords. Tools (Semrush, Surfer, SE Ranking, Ahrefs Brand Radar, Peec AI) ask models a set of questions and check whether your brand comes up in the answer.
- Results are unstable. The same model answer changes from day to day, so look at the trend over many days, not a single snapshot.
- Classic SEO is still the foundation. Models that use search pull from pages that rank well and have clear, specific content.
- Content structure matters. A short answer up top, lists, tables and dated data are more likely to end up in citations.
- Off-site mentions count a lot. Reviews, rankings and discussions on other sites shape what a model says about your brand.
How to choose
- One site, small budget - NeuronWriter Bronze plus Google Search Console.
- You write a lot of content - NeuronWriter, or Surfer for bigger budgets and team workflows.
- You run an agency with clients in several countries - Semrush or Ahrefs.
- You build links - Ahrefs.
- You want to track ChatGPT visibility without changing your SEO tool - the AI Search add-on in SE Ranking or Surfer's AI Search Analytics plan.
- Zero budget - Semrush Free, Ahrefs' free tools and Google Search Console.
Common mistakes
- Mass-generating AI content for keywords - optimizing for a word list won't replace specific, verified knowledge. Thin content won't hold its rankings.
- Treating the content editor score as the goal - 100 points in Surfer or NeuronWriter doesn't guarantee rankings. Treat it as a checklist.
- Buying an all-in-one suite when you need one feature - you don't need Semrush at $100+ a month just to write articles.
- Ignoring Google Search Console - Google's free data is more accurate than any tool's estimates.
- Measuring AI visibility on a handful of prompts - a few questions don't give a representative picture. Build a set of several dozen real customer questions and track the trend.
- Trusting one tool's search volumes blindly - volume estimates differ between tools, so cross-check important keywords.
