How it works

From problem to understanding in three steps.

01

Type or photograph

Use the keypad, paste LaTeX, or snap a photo of a textbook problem with the mobile app's OCR.

02

See every step

Open Omnia explains the reasoning at each stage — not just the final answer. Skip steps if you already know them.

03

Practice & retain

Linked practice problems reinforce the concept. Built-in notes connect the problem to the underlying theorem.
