Problem
Most learning tools lose the big picture just when the user needs it.
Search gives you one result. Textbooks give you one route. AI often gives you one fluent answer. None of them reliably show the shape of the field first.
Search
Fast local answers, weak global structure.
Textbooks
One authored route, limited comparison space.
Glossaries
Terms without dependency or argumentative shape.
AI output
Fluent summaries that can hide provenance and uncertainty.
