Maps of your vocabulary. Different views, different intuitions.
2D · frequency × memory state
Frequency frontier scatter colored by memory bucket. The next-to-learn frontier highlighted. Best view to find what to study next.
Open Lattice3D · domain × frequency × confidence
Radial polar projection. Domains as wedges around the perimeter, frequency as concentric rings, confidence as height.
Open HaloPer-domain · easy ↔ rare swim lanes
Each row is a domain. Easy words on the left, rare on the right. Gold marker shows your frontier per domain - what to push into next.
Open Frontier3D · semantic × Lattice shells
Knowledge globe. Semantic similarity by direction, frequency by radius, seven translucent Lattice shells (0 First Contact through 6 Native-feeling). Drag to rotate.
Open SphereEach domain · its own star system
Every cluster you've started learning becomes its own constellation. Lit stars by memory state, frontier outlines for what's next.
