Rekapu – Learn while procrastinating. Answer flashcard to unblock sites
Hi HN! I built Rekapu to learn Polish after moving from Ukraine to Poland. The problem is - I work remotely for US companies in English, and most people around me speak English or I can use self-service checkouts, so there's basically zero pressure to actually learn. But I wanted to improve. Being honest with myself, I had to acknowledge that with my cooked attention span, relying on willpower or strict schedules just wasn't going to work. The insight: My most consistent habit is procrastinating on HN, Twitter, and news sites. It happens automatically every day, regardless of my mood or…

In plain words
Rekapu is a browser extension that blocks access to time-wasting websites unless the user answers a flashcard question first. Designed for language learners with limited willpower for traditional study methods, it leverages procrastination habits by requiring just one flashcard per session before granting site access. The tool pairs learning with the automatic behavior of visiting blocked sites, turning unplanned procrastination into productive study moments with minimal friction.

Transform your distractions into learning moments with scientifically-proven spaced repetition. 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. Science-backed…from github.com

Anki/Duolingo-like app using educational YouTube videos2024 · platoedu.org · ▲289Hi HN, I watch A LOT of educational YouTube videos but wasn't forgetting a good chunk of the details because I was only really passively watching. So I made a tool that generates quiz questions/flashcards from YouTube videos, and uses spaced repetition like Anki or Duolingo to keep it in memory. Let me know if you find it cool/useful (or terrible ) or if you want to know a bit about the details!

When I was getting into web development I used a combination of Anki and git to help me quickly learn and retain skills. Figuring there might be demand for a product that uses the same strategy (without the requirement that you already know Anki and git), I created SkillPress. No account is needed to start learning. I would greatly appreciate any feedback or suggestions.
