The provider now positions itself as a platform for visibility in both traditional and AI-powered search: it aims to measure how often a brand is mentioned in AI assistants' answers and to improve content for SEO and generative engine optimisation (GEO) (as of October 2026).

AI-assisted content creation means producing text, images or other content with the help of generative AI, for example for websites, newsletters, product descriptions or social media. AI quickly delivers drafts, variants and translations, while subject expertise, brand voice and fact-checking remain human tasks. Clear guidance on audience, tone and sources helps. Example: bullet points about a new offering become a draft blog post and three social media posts.
