The Stack Builder
Build your cognitive protocol.
A short, considered assessment of how your work taxes your cognition — then a personalised protocol, transparently reasoned. We read your demands and lifestyle, not your medical history, and we tell you honestly what the evidence does and doesn’t support.

Building a stack, answered.
- How do I build a nootropic stack?
- Start from your goal, not from a product list. KÖGN's free assessment asks a short set of questions about how your work taxes your cognition — the shape of your demand, your state, and what you're orientating toward — then routes you to one of four cognitive-mode protocols, or tells you honestly if you don't need a stack. It's held to the same evidence standard as the KÖGN Dictionary.
- What nootropics should I take?
- There is no single answer — it depends on what you are asking your mind to do. Sustained deep work, constant context-switching, and depleted recovery each point to different support. The assessment maps your profile to a protocol; the Dictionary lets you research ingredients by goal first. Browse ingredients by goal →
- Is a personalised nootropic stack worth it?
- A personalised stack is worth it when it is built from your actual cognitive demands rather than a generic formula — fewer, well-chosen ingredients beat a long, vague list. KÖGN's assessment is honest by design: if you do not need a stack, it will say so.
- Is the KÖGN assessment free?
- Yes. The assessment and your cognitive profile are free. The personalised protocol is a subscription, and the recommendation engine is ring-fenced from commercial interest — the profile reads the same whether or not you subscribe.
