STEMReader makes it easier to read, navigate, and study technical textbooks and PDFs.

With STEMReader, you can: • Jump to equation and figure references Tap recognized references while reading to quickly view the referenced equation or figure without losing your place. • Navigate textbook contents Browse the structure of your textbook and move quickly between sections. • Find and work through problems View detected exercises and problems without searching through the entire document. • Work with exercises using Problem Solver Open detected textbook problems in a focused workspace designed to make working through exercises easier. • Take PDF notes Keep your notes connected to the documents you are reading. • Use scanned textbooks and PDFs STEMReader is designed to work with technical documents, including textbooks that were originally scanned rather than created as digital PDFs. Whether you are studying mathematics, physics, engineering, or another technical subject, STEMReader helps turn a static textbook into a more useful workspace for learning.
