Company Launches

Quazel is now Univerbal.

A brand new name, look, and features for your AI-Language Tutor.

When we launched Quazel we focused on building the best AI Language Tutor app out there.

Lots of people tried it and loved it, except everyone struggled to spell it… or find it.

Quazel makes sense in German, as a play on quasseln (to chat), but that’s about it. And, as a language learning app, we wanted to be uni…versal, after all - so we needed a name to reflect that.

Introducing - Univerbal! A brand new name, look, and feel for the AI Tutor in your pocket. With lots of new features, too.

Conversational language practice by talking to AI

What is your company going to make? Please describe your product and what it does or will do.

It's a language learner chatbot app that teaches people conversational fluency in a foreign language. In dynamic and unscripted conversations with an LLM-based AI users can practice their language skills. Learners record themselves saying something and the AI responds in turn, just like in a conversation with a human.

With the scene builder, learners can customize what they want to talk about by filling in the blanks: "I want to talk about CHESS with A GRAND MASTER in A HOTEL LOBBY while roleplaying A NOVICE CHESSPLAYER". Thus learners can exactly tailor the scene to their desires.

We also offer predefined scenes which focus on different areas of vocabulary useful to learners (e.g. getting to know someone, public transportation, etc). Additionally, in every scene, users can analyze the grammar of their responses or use hints to help them out when they get stuck.

Obviously, there is more to it but it's easiest if you just try our beta yourself at talk.quazel.com
