Hello! Creator here. This app shows word evolutions in a visual format similar to a family tree. I made this because I'm really interested in how words relate to one another. For example "magnanimous" can be understood through its relatives "magnificent" and "unanimous"
Working on it has been both a blast and a slog (~6 years on & off). I used DL NLP (thanks fast.ai!) to convert written etymology paragraphs into a database of words and connections. The accuracy is roughly 99%. There are about 1.4M words and 1.3M word-pair-connections across 13k languages. The most interesting thing has been finding Proto-Indo-European roots, like "h₂enh₁", which is a 10k-year-old reconstructed word meaning "breath", that has about 1k modern day descendants ranging from "nose" to "anemone".
I've had about 30k downloads since 2017 and I'm making a modest amount from sales of premium (to removes ads), which I'd like to grow. I'm thinking maybe another visualization style that's only available in premium? So I'd be very appreciative of any feedback at all!
