## What is STEMReader?

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

Instead of constantly scrolling through hundreds of pages to find an equation, figure, chapter, or exercise, STEMReader analyzes your document and builds tools around its structure.

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.
