About RootTrax
Why It Exists
Words have always fascinated me — not just what they mean, but where they came from, and how they traveled. "Algebra" from Arabic. "Safari" from Swahili. "Robot" from Czech science fiction. Every word is a compressed history of human contact, migration, and invention. I wanted a tool that made that history visible — not just as a footnote in a dictionary, but as a journey you could follow on a map.
RootTrax started as a personal desktop app I built for myself on macOS. The map was always the centerpiece — watching a word's origins move from ancient roots through the medieval world into modern English made etymology feel alive in a way that text alone never could. Eventually it seemed worth sharing, and so here it is.

Under the Hood
RootTrax is powered by Claude AI (Anthropic), which performs the etymology research and analysis for each query. Results are cached in a database to keep lookups fast and reduce redundant API calls. The maps use Leaflet.js with OpenStreetMap data.
