FAQ
What is Cairnote's primary learning method?
Cairnote utilizes active recall, a scientifically proven method where users retrieve information from memory rather than passively reviewing it. This involves hiding key points and then quizzing oneself to reinforce learning.
Can I use Cairnote to study from PDFs?
Yes, Cairnote allows you to import PDFs and cover text directly on the page. You can also highlight text and export the marked-up PDF, making it a versatile tool for studying existing documents.
How does Cairnote help with spaced repetition?
Cairnote incorporates the FSRS algorithm to schedule your reviews. This algorithm ensures that material you know well is revisited less frequently, while information you struggle with appears sooner, optimizing your learning efficiency.

No, Cairnote is ad-free. The developers state that no ads are present in the application, ensuring an uninterrupted study experience.
