WordFlippin

Hey IH! 👋

I just shipped WordFlippin after 3 months of drowning in paper flashcards while learning new words.

The problem I kept hitting:

• Physical cards scattered everywhere (desk, car, backpack)

• Zero idea which words I was actually struggling with vs. ones I'd mastered

• Reviewing everything equally = wasting 80% of my time on words I already knew

• Lost motivation when progress felt invisible

What I built: WordFlippin uses AI + spaced repetition to surface exactly the words you're forgetting at the perfect moment for retention. No more shuffling through hundreds of cards or guessing what to review.

Core features:

• AI-powered word generation with context-rich examples

• Smart spaced repetition with Daily, Weekly and monthly repetition.

• Progress tracking that shows what's actually sticking

What I'm working on next:

• Mobile app (currently web-only)

• Integration with popular language learning content (podcasts, articles)

Would love feedback on:

• What friction points stop you from sticking with flashcard apps?

• What more features you want in WordFlippin.

Happy to answer any questions about the build, tech stack or how the spaced repetition algorithm works!
