Having your own private English tutor 24/7 has never been easier. Kuba is your buddy — your friend on the journey to mastering English.
Powered by AI, he’s the digital clone of Jakub, the most-watched English teacher in Czechia and Slovakia.
Everything in the app is designed to finally make you speak English with confidence.
We built Kuba beyond textbooks — to teach you how to actually speak.
Fun, friendly, stress-free.
You’ll get personalized lessons where Kuba guides you step by step, just like chatting with a friend over a beer.
Whether you’re a complete beginner or advanced, Kuba has something special prepared just for you.
And all of it for a fraction of the price.
Kuba is your English buddy in your pocket.
Just open the app — he’s waiting for you.
In this version, we improved AI memory with profile building in Settings, added a motivational screen to help you stay committed, and fixed bugs.
