Active reading
Mark the ideas that matter, then study them.
Highlight important passages in your learning material and turn close reading into focused revision with Ultra Learn.

Keep attention close to the source
Highlighting is most useful when it captures a decision: this definition matters, this example resolves a doubt, or this paragraph connects two topics.
Ultra Learn keeps those moments beside the document so you can move from reading to review without rebuilding your context elsewhere.
Turn marks into useful revision
A highlighted passage can become a starting point for an explanation, a question, a note, or a flashcard. That gives each mark a job beyond decorating the page.
The result is a tighter revision set built around the concepts you actually noticed and the details your course material emphasizes.
Review with purpose
On the next pass, you can return to the selected ideas first, check them against the surrounding passage, and test whether you can explain them without looking.
That combination of source context and active recall makes highlighting part of a learning workflow rather than the final step.
