Your documents
This session only: each PDF you drop is read from scratch, and the list clears when the app restarts.
Made for reading with your ears
It handles the hard parts of a PDF: math, code, tables, graphs, illustrations and the rest of the page furniture.
Follow every word
Each word lights up as it's spoken. Click any word to start reading from exactly there.
Math that makes sense
Equations are read by meaning, like "x squared plus y", not as a jumble of symbols.
Figures explained
Charts, tables, diagrams, code and equations can each get a short spoken summary: turn on Summaries in Settings.
Built for real papers
Two-column layouts, headers, footnotes, references and journal clutter are handled, so you hear the paper, not the page furniture.
Easy to find your way
A clean table of contents, the original page beside the text, and pages that turn by themselves.

Tired eyes
Give your eyes a rest after a day at the screen, and let a calm voice do the reading.
