Show HN: PolyLia – Learn languages by challenging friends (open beta)

https://polylia.com/
3•ahmed_duski•8h ago
Hi HN!

I built PolyLia, a multiplayer app that makes learning a new language more engaging by turning it into a game of real-time challenges.

Unlike most language apps that focus on repetition or solo practice, PolyLia is about friendly competition — you challenge friends (or strangers) in quick language duels.

The app is in open beta and available here: https://polylia.com/download-page/

I’m looking for early feedback from language learners, educators, or anyone who enjoys gamified learning. What works? What doesn’t? Any ideas for features you'd like to see?

Everyone who joins now gets a Founder's Badge!

Thanks in advance — I’ll be in the comments all day to reply!
