Why does Notion appear in multiple categories?

Some tools like Notion span multiple use cases — it can serve as a sales wiki, marketing content calendar, and dev documentation hub. Each instance in a different category is independent, so you can set different experience levels per use case if needed, or simply select it once in your primary category. Tools that appear in multiple categories will automatically self-select when you choose them for the first category, saving you from choosing the same tool multiple times.
