You are writing B2B content and you want it to rank. You need an AI SEO tool. The two most-recommended options at this price point are NeuronWriter and Frase.io.

They look similar on paper. Both analyze SERPs. Both generate content briefs. Both use AI to score your content. But the workflows are different, the pricing models are different, and the results for B2B content specifically are different.

Quick Comparison: NeuronWriter vs Frase

1. NeuronWriter — Best for On-Page SEO Optimization

Try NeuronWriter → (affiliate link coming soon)

NeuronWriter is built around one core premise: analyze the top 30 SERP results for your target keyword, extract the semantic terms and concepts they use, and score your content against that benchmark. The higher your NeuronWriter score, the more semantically complete your content is relative to what is already ranking.

For B2B content marketers, this matters. B2B keywords often have specialized vocabulary — industry terms, technical concepts, acronyms — that you need to include for topical authority. NeuronWriter’s semantic analysis catches gaps you would miss manually.

Strongest features:

• Content score benchmarked against top-30 competitors (not just top-10)
• Term frequency analysis — shows exactly which terms to use and how often
• Internal linking suggestions based on your existing content
• AI paragraph writer to fill in scoring gaps without losing your voice
• SERP analysis shows which competitor pages score highest and why

Weaker than Frase:

• UI takes longer to learn
• Brief creation is less intuitive
• No answer-engine optimization (AEO) built in

Verdict: If you have existing content that is not ranking and you want to systematically improve it, NeuronWriter’s scoring and semantic analysis will show you exactly what to fix. Strong choice for content teams with an existing library to optimize.

Pricing: Bronze $23/mo (10 SERP analyses/mo). Silver $45/mo (30 analyses). Gold $69/mo (80 analyses). All plans include AI writing credits.

2. Frase.io — Best for Research and Brief Creation

Frase is purpose-built for the research and brief creation stage of content production. Where NeuronWriter’s strength is optimization, Frase’s strength is speed: you enter a keyword, Frase pulls the top SERP results, extracts their headers and key points, and gives you a structured brief in under 2 minutes.

For solo founders who write their own content, this brief-first workflow saves hours per post. Instead of manually reading 10 competitor posts to understand what to cover, Frase does it automatically.

Frase also added an Answer Engine Optimization feature that shows you which questions your content should answer to appear in AI-generated responses (Google AI Overviews, Perplexity). This is directly relevant for GEO optimization.

Strongest features:

• Fastest brief generation in the category — 2 minutes from keyword to structured outline
• Clean, intuitive editor that feels like Google Docs
• Answer Engine Optimization (AEO) for AI search visibility
• Topic research and question extraction from forums and PAA boxes
• Content score benchmarked against top competitors

Weaker than NeuronWriter:

• Semantic scoring depth is less granular
• Fewer SERP results analyzed (top 20 vs NeuronWriter’s 30)
• Internal linking feature is more basic

Verdict: If you are producing new content regularly and want the fastest path from keyword to publish-ready outline, Frase is the right tool. The $14.99/mo Solo plan is the most affordable entry point in the AI SEO category.

Pricing: Solo $14.99/mo (1 user, 4 documents/mo). Basic $44.99/mo (unlimited documents). Team $114.99/mo (3 users).

Which Should You Pick?

Choose NeuronWriter if: You have existing content that is not ranking and you want to optimize it. You write about technical B2B topics where semantic completeness matters. You want the deepest SERP analysis in this price range.

Choose Frase if: You are producing new content consistently (2+ posts/week). You want the fastest brief creation workflow. Budget is a priority and $14.99/mo vs $23/mo matters. You want AEO optimization built in for AI search visibility.

Use both if: You can afford it. Frase for brief creation, NeuronWriter for final optimization before publishing. They complement each other well.
