About this app

Study App turns anything you have to read into something you can listen to.

Import a PDF, paste a link or drop in your notes, and Study App reads it aloud in natural AI voices while highlighting every word as it is spoken. It was built for the material other read-aloud apps stumble on: technical books full of code, tables, flowcharts and diagrams.

WHAT YOU CAN LISTEN TO
PDFs, including long technical books and research papers
Web articles, just paste the link
Notes, emails and anything you can copy

Code blocks are read clearly and deliberately so you can follow along
Headers, footers, page numbers and citations are skipped automatically
Jump to any sentence by tapping it, in reflowed text or on the original page

A PLAYER FOR LONG SESSIONS
