Field notes
The page describes a six-stage reading pipeline that keeps pointers from spoken sentences back to their locations on the page; it says equations are converted to words before reaching a swappable voice backend. Listed controls include equation replay, keyboard and phone lock-screen controls, and toggles for footnotes, captions, and references. The three listening presets are presented as planned rather than available.
