GEO Optimization Tools Compared: PromptingCo vs Relixir vs Bear
GEO optimization tools are platforms that help brands improve how their content appears in AI-generated search responses from engines like ChatGPT, Perplexity AI, and Google AI Overviews. Generative engine optimization - GEO - is the practice of structuring and optimizing content so AI models are more likely to cite it when generating answers. PromptingCo, Relixir, and Bear are three tools tackling this problem from different angles.
The Princeton GEO research found that content optimized with statistics, citations, and clear structure saw up to 40% higher visibility in AI-generated responses. These tools operationalize those findings into actionable workflows.

What Does Each Tool Do Best?
PromptingCo: Understanding AI Perception
PromptingCo takes a unique approach to GEO by focusing on prompt simulation. The platform runs thousands of prompt variations related to your brand, product category, and target keywords across multiple AI models, then analyzes how those models respond.
How it works: You define your brand, competitors, and target topics. PromptingCo generates and runs prompt variations - "What is the best tool for X?", "Compare X vs Y", "How do I solve Z?" - across ChatGPT, Perplexity, Claude, and Gemini. The platform then maps which brands get mentioned, how they are described, and what content sources are cited.
Strengths: Prompt simulation gives you insight into how AI models perceive your brand across a wide range of query types. You can identify gaps - queries where competitors get mentioned but you do not - and understand the language AI models use to describe your product category. This intelligence informs not just your content strategy but your positioning and messaging.
Weaknesses: PromptingCo is stronger on the analysis and intelligence side than on the implementation side. It tells you what AI models think, but the content optimization work happens in your existing tools and workflows. Teams need the capacity to act on the insights.
Relixir: Ongoing Visibility Management
Relixir positions itself as a comprehensive AI visibility platform that combines monitoring, optimization, and competitive intelligence in a single dashboard. It is designed for ongoing management rather than one-time audits.
How it works: Relixir continuously monitors how AI search engines respond to queries in your space. It tracks your brand's citation frequency, identifies which content pages are being cited, and provides optimization recommendations for underperforming content. The competitive intelligence layer shows how your AI visibility compares to competitors over time.
Strengths: The continuous monitoring model means Relixir catches changes quickly - if an AI model stops citing your content after a model update, you will know within days rather than discovering it weeks later. The optimization recommendations are tied directly to monitored queries, making them immediately actionable.
Weaknesses: Continuous monitoring requires ongoing investment. Relixir is a subscription tool designed for teams that will use it regularly, not for occasional check-ins. Startups with limited content budgets may find it hard to act on all the recommendations the platform surfaces.
Bear: GEO Auditing
Bear takes the most focused approach - auditing your existing content for GEO readiness and providing specific recommendations for improvement. Think of it as a GEO-specific content audit tool.
How it works: You submit your content or website to Bear, and the platform analyzes each page against GEO best practices: content structure, definition clarity, statistic usage, citation quality, schema markup, and how well the content answers specific questions. The output is an audit report with prioritized recommendations.
Strengths: Bear is practical and implementation-focused. Instead of ongoing monitoring dashboards, you get a clear list of what to fix and why. The project-based pricing model works well for startups that want to optimize their existing content library before investing in ongoing monitoring.
Weaknesses: A one-time audit does not capture how AI models change over time. AI search algorithms are updated frequently, and what works today may need adjustment in three months. Bear is best as a starting point, not a standalone long-term strategy.
How Do These Approaches Differ from Traditional SEO?
Traditional SEO tools like Ahrefs and Semrush optimize for search engine rankings - getting your page to position 1 on Google. GEO tools optimize for AI citations - getting your content selected as a source when an AI model generates an answer.
The difference between GEO and SEO is meaningful in practice. A page can rank first on Google but never get cited by ChatGPT if the content is not structured in a way that AI models can easily extract and reference. Conversely, a page on page two of Google results might get cited frequently by Perplexity because it provides the clearest, most direct answer to a specific question.
GEO optimization tools fill this gap. They help you optimize content for AI search specifically - ensuring your definition paragraphs are clear, your statistics are cited, your structure uses question-based headings, and your content directly answers the queries AI models process.
Which Tool Should You Choose?
Choose PromptingCo if you want deep intelligence on how AI models perceive your brand and where your gaps are. It is the best starting tool for brand positioning research in the AI search era.
Choose Relixir if you need ongoing AI visibility management and have the team capacity to act on regular optimization recommendations. It is the most comprehensive option for sustained GEO improvement.
Choose Bear if you want a practical, project-based audit of your existing content with clear recommendations for improvement. It is the best entry point for startups doing GEO optimization for the first time.
At Conbersa, we see these tools as part of a broader AI search optimization strategy that includes content structure, distribution, and multi-platform presence. The tools provide data and direction - but the real work is creating content worth citing.
