The Tana Illusion: Supertags Won't Save You

Is Tana better than Notion?

On pure structuring power, in several ways yes, and that is exactly where the trap is set. Tana is an outliner where every line is a node, and any node can carry a supertag that turns it into typed, queryable data with custom fields. The headline advantage over Notion is real: in Tana a single node can belong to more than one supertag at once, where a Notion page can live in only one database. You write freely in an outline and layer on structure later, instead of building rigid databases upfront, and reviewers note this makes the workspace feel almost self-organizing. Deep AI is built in.

So if the question is which tool can model your knowledge more flexibly, Tana usually wins. But that is not the question that determines whether it helps you.

Supertags need an ontology you may not have

A supertag is a way to encode an ontology: a model of what things are, what properties they have, and how they relate. That power is only useful if you already possess an ontology, a clear mental model of how your domain is actually structured. Hand a precise structuring tool to someone without an internal structure, and one of two things happens: they freeze, unsure how to set anything up, or they build an elaborate, beautiful taxonomy that organizes nothing real. The supertag cannot supply the ontology. It can only express one you already hold.

This is why Tana’s learning curve bites. As even enthusiasts note, supertags and queries take real time to learn, and the difficulty is not really the software, it is being forced to decide how your knowledge is shaped, a decision a vague mind cannot make.

Dimension	Notion	Tana	The First Brain
Structure model	Pages and databases	Nodes and supertags	Connected concepts
Flexibility	One page, one database	A node in many supertags	Any idea, any link
What it requires of you	Upfront structure	A clear mental ontology	Active thinking
What it cannot supply	Your judgment	Your ontology	Nothing, it is yours

Build the ontology first

The verdict is that Tana rewards a clear First Brain and punishes a vague one harder than Notion does, precisely because it gives you more rope. With a real mental model of your domain, supertags become a powerful amplifier; without one, they become the same trap as endless app-tweaking, the avoidance dissected in over-engineering the mind, with extra steps. The tool is downstream of the mind, which is the recurring teardown lesson in the death of the second brain app market and the same conclusion we reached about Obsidian versus the First Brain.

So build the ontology where it actually lives: in your head, through the structuring work of structuralism in note-taking and the connecting work of cognitive mapping. Then Tana’s supertags have something to express. Without that, no supertag will save you. That is the argument of Building Your First Brain, free for the first 1,000 readers.

Frequently asked questions

Is Tana better than Notion?

On structuring flexibility, often yes: Tana’s supertags turn any node into typed, queryable data and a node can belong to many supertags, which is more flexible than Notion’s one-page-one-database model. But that power only helps if you already have a clear mental ontology. As Building Your First Brain by Lawrence Arya frames it, supertags can express a structure you hold but cannot supply one, so a vague mind gets little from Tana regardless.

What are Tana supertags?

Supertags are Tana’s core feature: applying one to a node defines what that node is and attaches custom fields and metadata, turning a plain bullet into structured, queryable data. A single node can carry multiple supertags, letting it live in several categories at once, which makes the system flexible but also demands that you know how your information should be modeled.

Is Tana worth the learning curve?

It can be, if you have a clear sense of how your knowledge is structured and will use the supertag and query system to express it. If you do not, the learning curve mostly forces you to confront an ontology you have not built, and you risk creating an elaborate setup that organizes nothing. Build the mental model first, then the curve pays off.

Why is my Tana setup so complicated?

Usually because you are trying to design structure in the tool before you have it in your head. Powerful structuring features let you build endlessly without a clear underlying model, producing complexity that does not reflect real understanding. Simplify by first clarifying how your domain is actually organized, then encode only that.

Does a better note app make you more organized?

Not by itself. A more capable app gives you more ways to structure information, but organization comes from having a clear mental model of what you know and how it relates. Without that internal structure, a powerful tool tends to produce elaborate disorder. The app amplifies the clarity, or the lack of it, that you bring.
