Software

SemNA — Semantic Network Analysis

Networks of meaning, made legible.

A free, no-code desktop app that turns text into semantic networks—explicit co-occurrence networks and latent word-embedding networks—with structural measures and interactive exploration. Runs entirely on your machine; your text never leaves your computer. Available for macOS (Apple Silicon) and Windows.
