Use cases · Why Onnie

Studying

Learning that compounds in the place

Studying fails when notes are a graveyard and every session restarts cold. Onnie is where learning compounds — Knowledge, spines, and Routines in one room.

Notes apps don’t teach the next session

Highlights pile up. Folders lie. Chat tutors forget yesterday. Exam week means re-finding what you already knew.

// on onnie

Knowledge compounds; Work holds the arc

Atomic notes and hubs keep ideas connected. Work holds the exam or research arc. Pages become digests; Routines keep review honest. Agents help; humans confirm what enters the graph.

This is not a second notes app. It is a graph you can Study as cards and reason as edges — same room as the spine that carries you to exam day.

How a course actually compounds

Click each step. Graph for structure — Study for cards — Work for the arc. Not a chat transcript pile.

Hub as lens — not a folder

Crown a course hub. Members pop; rest dims. Typed edges mean something. Agents suggest; you confirm. Graph and Study are the same Knowledge surface.

Product Knowledge DNA: Graph (hub lens, typed edges, suggest→confirm) and Study (card browse). Toggle both — same surface, studying residue.
