Rekapu: Block Distractions, Learn with Flashcards

Learn while procrastinating

What is Rekapu?
Rekapu is a browser extension that combines spaced repetition learning with website access control. Instead of blocking you with a wall, it shows you flashcards when you visit distracting websites. Your knowledge grows while your focus improves - no extra apps, no dedicated study time, just learning integrated into your day.

The key difference: Unlike traditional website blockers that redirect you to a new page (losing your scroll position and context), Rekapu uses an overlay approach. After answering a card, you continue exactly where you left off - no reload, no lost context.
