An entity is a distinct concept, thing, person, or term related to your topic. Search engines and AI systems understand pages through the entities they mention and how those entities relate. Covering the entities a reader expects for a topic signals topical authority and completeness, which improves both classic rankings and your odds of being cited in AI answers.

Everything runs in your browser. You paste your content and enter a topic; the tool extracts the meaningful terms and entities present in your text, builds a heuristic list of related terms commonly expected for that topic, and compares the two. Nothing is sent to a server and no AI API is called, so it is fully private and unlimited.

It is generated heuristically from your topic using common modifiers, related concepts, and question patterns (definitions, comparisons, costs, examples, best practices, tools, and so on), combined with the salient terms found in your own text. It is a directional guide for spotting obvious gaps, not an exhaustive knowledge graph, so use judgment about which suggested entities truly belong.

Review each missing entity and decide whether it genuinely belongs on the page. Add sections, sentences, or examples that naturally cover the relevant ones — for instance, addressing cost, alternatives, or how-to steps you had omitted. Filling real gaps deepens the page; ignore suggestions that are off-topic to avoid keyword stuffing.

No. The goal is relevant completeness, not cramming every related word in. Covering entities that a user genuinely expects strengthens the page; forcing in tangential terms dilutes focus and reads unnaturally. Treat the gap list as prompts for substantive additions, not a checklist to keyword-stuff.

Indirectly. Paste a competitor's content and the same topic to see what entities they cover, then run your own content to compare. While it does not crawl competitors automatically, this manual comparison is an effective, private way to spot coverage that rivals include and you do not.

No, it complements it. Keyword research tells you what people search; entity coverage tells you whether your content fully addresses the concept behind those searches. Use both: find the keywords, then ensure your page covers the supporting entities so it reads as a complete, authoritative resource.
