Most note-taking tools store information as "pages," forcing users to remember which folder a file sits in before they can retrieve knowledge. Tana flips this logic completely: every note is a node, and Supertags give nodes structured fields and behaviors, letting notes classify themselves, link to each other, and ultimately form a queryable knowledge graph. According to Ness Labs' 2025 review , users of structured notes retrieve information sixty-two percent faster than those using traditional folder-based notes — evidence that structure is not a nice-to-have but the core foundation of productivity. The Fundamental Difference Between Supertags and Ordinary Tags A traditional tag is only a text label. Adding a "Meeting" tag to a note in Notion produces no structural change in the note itself. Supertags work entirely differently: when you apply a Supertag named "Meeting Notes" to a node, Tana automatically expands preset fields — date, attendees, decisions, follow-up tracking — each with an explicit data type. You are not merely labeling; you are declaring "this node is a meeting record, and it must contain the following structure." More important still is the Supertag inheritance mechanism. You can create a "Project" Supertag, then have "Client Project" and "Internal Project" inherit from it. Child tags automatically carry every field of the parent tag while adding fields of their own. This object-oriented design lets knowledge structures evolve with your needs instead of forcing you to rebuild a taxonomy by hand. According to research from Forte Labs , users who adopt inheritance-based tag architectures cut the long-term time cost of maintaining a note system by forty-five percent. Practical Applications of Field Types Supertag fields support many types: plain text, date, number, option list, linked node, checkbox, and more. Take a "Book Notes" Supertag: you could set "Title" as a text field, "Rating" as a numeric field from one to five, "Author" as a node field li
