Type a sentence. DarwinX tokenizes it, tags each word by part of speech and surfaces its morphology (number, tense, degree), the way a spaCy / displaCy view does. Rule-based and fully client-side, so nothing leaves your device.
A compact sign language of our own: each glyph is a morpheme (a root or an affix). Click glyphs to compose a sign string, and the lab decodes the morphology into meaning, the same idea as the scat riff - the meaning lives in the pattern, not the sound.
