DEEP DIVE

Evaluating the AI Visibility Tool Landscape

The measurement models that underpin SEO are no longer sufficient on their own. Generative Engine Optimisation (GEO) challenges us to rethink what visibility means and, more importantly, how to measure and quantify Large Language Models (LLM) and Artificial Intelligence (AI) search best practices.

In this study, we have investigated 26 different AI visibility tools during Q4 2025, aiming to find the best tools to help navigate in the GEO landscape and meet our criteria.

AI visibility tool assessment criteria

Measuring GEO and AI search requires an extensive measurement framework and solid plan for what to measure before evaluating which tools can provide the answers. LLM search visibility tools are still relatively new, and the tooling ecosystem reflects that. We assessed each tool against eight enterprise-grade criteria.

  1. AI platform coverage

  2. Depth of analytics

  3. Global reach and multi-language support

  4. Content gap analysis

  5. API integrations

  6. Data accuracy

  7. Transparency of methodology

  8. Enterprise and agency readiness

From this process, six tools were researched in depth:

  • Profound

  • Nimt

  • Promptwatch

  • Writesonic

  • Otterly

  • AI Waikay

After a deeper research of the six tools, three stood out.

The top three: Strategic Options

After extensive testing of the market, three GEO visibility tools best met the above criteria; Promptwatch, Writesonic and Profound.

Promptwatch (NL): Balanced Visibility and Compliance

Promptwatch offers broad feature coverage, strong data transparency, and a flexible structure that supports detailed analysis across clients, markets, and prompts. Being based in the Netherlands also means a strong understanding of EU regulatory requirements, an important factor for many organisations. Reasons why Promptwatch stood out:

  • Comprehensive monitoring across all major AI platforms

  • Reproducible, verifiable data

  • Clear and transparent metrics

  • Flexible setup for detailed, client-level analysis

  • Existing and evolving API integrations

  • Direct access to product developers

The multi-monitor structure allows tracking prompts, products, and markets separately while maintaining a central overview, making it easier to detect shifts, demonstrate value, and act quickly.

Writesonic (US): High-Volume Content Execution

Writesonic excels where analysis and execution need to live in the same workflow. In addition to GEO and SEO monitoring, it offers AI-driven content creation tools, enabling teams to turn insights directly into copy. It is best suited for high-volume content strategies and rapid experimentation which was not the primary focus in this study.

Profound (US): Advanced Analytics for Enterprises

Profound is built for depth, delivering sophisticated analytics across multiple AI engines, including share of voice, sentiment analysis, and conversation-level insights. It also provides demographic data and estimates of prompt volume. These figures should be treated as directional rather than exact, as they are based on anonymised modelled datasets rather than direct data from AI search platforms, which can introduce sampling bias, especially for niche audiences.

Profound is particularly well suited to large organisations that require detailed, LLM-specific reporting and strategic intelligence rather than content production capabilities.

A best practise for choosing AI search visibility tools

In summary, LLM-driven search is still an emerging field, and definitive best practices have yet to be established. However, it is clear that structured measurement matters. By defining what to measure, how to measure it, and which tools can be trusted, organisations can move closer to a search visibility measurement process. A solid AI search visibility tool framework enables teams to act on real insights, effectively benchmark, and adapt as models evolve. In a landscape where uncertainty is the only certainty, measurement becomes the anchor.
