Entity Explorer

Entity Explorer is a free tool from Marketer's Center for deep entity research and visual entity maps. Starting from a topic, it categorizes the subject, produces content ideas to brainstorm from and suggests a possible content structure for a page, showing the topic the way a search engine sees it so the writer can optimize content. Users can edit entities, add subtopics in bulk by pasting keywords or entities, and generate ideas to strengthen existing content from keyword analysis or concepts. A free account saves the maps. AI-generated related entities on any node of a map work when the user supplies their own OpenRouter API key and, if wanted, a model, and the key is stored encrypted. The aim is more authoritative content and an end to stalled writing. Marketer's Center also runs white label marketing services.
