Sophiastra

Sophiastra is a note app for Mac that gives your thinking depth.

Wisdom (sophia) builds up like layers of rock (strata). Place your topics on a map, write inside each one like a chat, and dig into deeper layers as your ideas grow.

・Build in 2D — arrange your ideas as a pyramid and see what you still don't understand
・Explore in 3D — see layers stacked together and discover unexpected connections
・Free, no ads, no sign-up — your notes are saved only on your Mac
