#1 English-learning appYou're investing in company English. But do you know if it works?
You pay for lessons you can't measure. Who's making progress? How often does anyone practise? Is there a real impact? Without data, you don't know.
Company English you can finally measure.
Kuba gives you reports and shows you the numbers: who's practising, how much they speak, how often they come back and where the team is really growing. But above all, it's fun — tailored to each employee by AI.
Hi, I'm Kuba.
“Schools teach grammar. Apps teach translating. Nobody teaches speaking.”
I taught English for years — thousands of people, one conversation at a time. And I kept seeing the same thing: smart people who understand everything, but freeze the moment they have to open their mouth.
So I cloned myself. Seriously. I took everything I know and put it into an AI version of me that talks to your people, corrects them and pushes them forward — exactly the way I would. Except it's available 24/7, never gets tired and never judges anyone.
Your employees don't study in the app. They talk. Every day. And one day it hits them — hang on, I'm actually speaking English.
Three things that make Kuba different.
Talk to Kuba. Anytime. About anything.
Kuba built an AI version of himself that talks to your people like a real teacher — except it's available 24/7, never gets tired and corrects every mistake without anyone having to feel embarrassed. The more people talk, the better they get. It's that simple.
- Grammar & pronunciation corrected in real time
- Adapts to each employee's level and interests
- Available 24/7 — no bookings, no judgement
Short videos that actually teach.
Micro-lessons that feel like scrolling your favourite app — except your team is genuinely learning. An interactive quiz after every clip so it sticks. Perfect for five minutes between meetings.
- Short, addictive format — the kind people choose themselves
- Interactive quizzes right after every clip
- New content every week — it never gets stale
A plan made to measure. Streaks, badges, daily goals.
No guessing what to study next. A personalised plan adapts to each level and keeps people going with streaks, badges and daily goals. Every lesson feels like a game — but the results are real.

- Streaks, badges and rewards for a bit of team rivalry
- A personal notebook of words, mistakes and videos
