Frequently asked questions
What exactly does the checker measure?
It generates real questions people ask in your category, runs them through Gemini with web search, and analyzes whether your brand shows up, in what position, and with what tone. You choose whether to check your visibility, your reputation, or both.
Why only Gemini and not ChatGPT?
To keep the analysis free and fast we use Gemini only, with web search. Lumen AI's continuous monitoring covers ChatGPT, Gemini and Perplexity.
Is it really free?
Yes. The instant analysis and the email report cost nothing and need no card.
AI is already talking about your category. Make it talk about you.
Set up your brand in 2 minutes and find out today what ChatGPT, Gemini, Google AI Overviews, Claude, Perplexity and Copilot say when people ask about your market.
