Citable is an AI-visibility and citation monitoring platform for brands. It tracks how your brand is mentioned and cited across generative AI answer engines such as ChatGPT, Perplexity, Gemini, Claude and Grok, then turns that data into share-of-voice reporting you can act on.
Monitor how often your brand is named or cited in answers from generative engines including ChatGPT, Perplexity, Gemini, Claude and Grok, rather than only in classic search results.
See which prompts, topics and questions trigger a mention of your brand, so you can tell where you already appear in AI answers and where you are absent.
Compare your citation volume and presence against named competitors to understand relative share of voice inside AI answers.
Break visibility down by audience persona and by geography, so localised or niche-specific gaps in AI recommendations are easier to spot.
