Jakub Čáslava, known as Kubova English, is a creator, teacher, and entrepreneur who has been able to explain even the most complex grammatical concepts in an entertaining way. In my interview Reels Talk byAndré, he describes how he went from “drawer” raps and village discos to his own app with an AI avatar, which is now receiving great reviews from users and helping people learn English smartly and without embarrassment.
When the word networking came up, Kuba admitted that he used to roll his eyes: “In our village, networking sounds almost like procrastination… but now I’m really meeting interesting people.” His perspective is changing as he grows and, as he says, “learning every day”. From the original skepticism, there is now a pragmatic approach. Contacts make sense if they lead to valuable projects and not just “going somewhere to drink”.
What sustains Kuba? Online courses have long dominated, but now the focus is shifting to a mobile app with an AI avatar that speaks just like Kuba. A team of about 10 people worked on the development, which took over six months. The app quickly gained an audience: “We have a 4.9 rating and most importantly – it really helps people. We see that they learn English because of it.”
Kuba openly admits that the transition from a “one-man show” to product development was a lesson in patience. Because an idea that he used to implement in an hour is now being realized over months. At the same time, he reminds that ideas are the easier part. Keeping focus and completing them is harder.
When it comes to Kuba Čáslava, you might think of his educational raps that have been circulating on social media. He explains topics like articles, conditionals, or tenses with rhythm and humor: “I’ll teach you with rap, so it’s not dry…” he rapped in the interview itself. He wants to take the idea even further into a live format – an evening combining stand-up, rap, and practical exercises in English. Yes, it sounds crazy, and that’s precisely why it makes sense.
Kuba also described his first entrepreneurial chapter, the Inferno club. It was a school for him, one he didn’t even want to return to. In retrospect, he sees this period as a necessary training to clarify where he really wants to go. How did he get there? And what happened there?
