From German pun to a name everyone can spell

After becoming part of Y Combinator’s W23 cohort, we set out to build the best AI language tutor app - loved by tens of thousands of users. But there was one big problem: Quazel (a play on the German “quasseln,” meaning “to chat”) was nearly impossible for non-German speakers to spell, search for, or remember.

With a global vision for accessible, interactive language learning, we chose a name that reflects our universal mission: Univerbal.

Why the change: Quazel to Univerbal

  • 50,000+ downloads at launch!

  • Great feedback - but users struggled to spell, find, or recommend “Quazel”

  • Goal: A universal name that’s intuitive, memorable, and global

  • Univerbal is for everyone, everywhere - join our worldwide community!
