Structurepedia builds interactive knowledge trees that break a subject into visual branches, letting you map a field and drill into the parts you actually need to learn.
Every topic is presented as an expandable tree so you can see the whole field at once and zoom into the branch you need.
Colour, hierarchy and connecting lines do the explaining, which helps when a written article would be too linear or too long.
Nodes on a tree lead to deeper material on the same subject, so an overview quickly becomes real research.
Ask the search interface for a subject and get a structured map back instead of a list of unrelated links.
