Marsu.ai is a Finnish SaaS service that measures how companies and products appear in ChatGPT, Gemini, Perplexity, Copilot and Claude. It helps identify visibility gaps, monitor competitors and improve website GEO structure based on measurement results.
A company operating in the Helsinki metropolitan area achieved 100% visibility across its 35-point product portfolio in a ChatGPT measurement on 31 August 2026. The result was achieved in 158 days after the website was optimised, in a highly competitive sector. According to Statcounter’s August 2026 measurement, ChatGPT accounted for approximately 80–85% of AI chatbot usage across the Nordic countries. That makes 100% visibility in ChatGPT responses a particularly significant achievement. The result was achieved with Marsu.ai’s website GEO optimisation and AI visibility monitoring in collaboration with the company that implemented the website.

GEV (Generative Engine Visibility) measures how often and in what way a company or its products are mentioned in generative AI search responses — such as ChatGPT, Google AI Overview, Perplexity, CoPilot and Claude. Traditional SEO tracks search rankings e.g. in Google; GEV tracks what AI says about your company when asked.
Marsu.ai uses native manual measurement: an expert performs queries directly on AI platforms as digital craftsmanship in the same way as a real customer. This produces a more accurate picture than API-based automation, where results differ from the user experience.
API queries produce different results than searches done through the user interface — AI models behave differently depending on context, session history and platform version. Manual measurement reflects what your customers actually see.
The analysis produces prioritized action proposals: adding an llms.txt file, JSON-LD structured data, reformatting content into question-and-answer format, and website structures suitable for AI search engines. Each recommendation is justified by GEV measurement results.
The GEV service includes a baseline measurement, creation of AI optimization files for the website, and a monthly tracking report for the entire product portfolio. Tracking reports concretely show whether your company's AI visibility has improved and in which search types.
The service is particularly suitable for SMEs, expert organizations and brands whose customers use AI searches to support purchasing decisions. By industry, the most interesting target groups are accounting firms, law firms, consultants and companies offering specialized products or services.
The impact of technical changes (llms.txt, schema) on AI indexing can be seen within 2–6 weeks. The impact of content changes is typically 4–12 weeks. GEV tracking measures changes precisely, so progress can be verified.
GEO is the next phase of SEO: website content and structure are optimized so that AI systems find, understand and cite your company in relevant searches. It covers technical structure, content format and building authority in the AI ecosystem.

GEV (Generative Engine Visibility) refers to how visible a company or its products are in the responses of generative AI services. It shows how often and in what context AI mentions your company when potential customers ask about products or services in your industry.
GEV is calculated by tracking a company's mentions across predefined search queries on multiple AI platforms. For each query, it is recorded whether the company is mentioned and at what position it appears relative to competitors. The results form an overall index describing visibility relative to the market.
Marsu.ai currently monitors the following services: ChatGPT (OpenAI), Gemini (Google), Claude (Anthropic), Perplexity, and Microsoft Copilot. Additional services are added as the market evolves.
The number of queries depends on the industry and the agreed monitoring package. A typical tracking report analyses dozens of questions covering different product categories, stages of the buying process, and geographical areas. Questions are tailored to the company's product portfolio.
The baseline measurement is carried out monthly, covering the entire product portfolio across all monitored AI platforms. More frequent monitoring is available by agreement. Every measurement is stored historically so that progress can be tracked over time.
In the competitor analysis, the same search queries are run while also tracking competitors' mentions in AI responses. This lets you see not only your own company's ranking but also which competitors AI favours in responses and in which categories you are stronger or weaker than market leaders.
The client receives a monthly tracking report that includes: GEV index development over the period, results by product and service category, comparison with key competitors, and prioritised recommendations for improving visibility. The report is available both as a PDF and as an interactive online view.
At best, product portfolio visibility can reach 100%. This means that all selected products are found in AI service answers for their defined questions. The result depends on the industry, questions, region and AI service being monitored, so the level cannot be promised in advance.
