Case study · Xeropan
A language lesson in five minutes. For five million learners.
Xeropan is a playful language learning app with AI conversation, video lessons and personalised review, on iOS, Android and in the browser. In Hungarian schools, it powers the KRÉTA Foreign Language Preparation Module (IFM), part of KRÉTA, Hungary's national school administration system. We've been developing the product with the Xeropan team for years.

The challenge
Language learning doesn't fail on knowledge, it fails in the second week.
Everyone starts. Few keep going. A language app has to be a teacher, a coach and a game at once: short lessons, instant feedback and a reason to open it again tomorrow. In schools, it also has to fit the way teachers work and the processes of KRÉTA.
Five minutes on the bus, not an hour at a desk
Language learning doesn't fail on the textbook, it fails on consistency. The app has to fit into a few spare minutes a day, and bring learners back tomorrow.
You need to speak, not just tap
Multiple choice is quick, but it doesn't prepare you to speak. Learners need to practise pronunciation and real conversation too, on their phone.
In school, it has to work for the teacher too
With a whole class, a good app isn't enough: students need to sign in, join groups, get homework and receive grades, the way they're used to in KRÉTA.

The goal
Miss a day, keep your streak.
Small decisions that bring learners back tomorrow.
The solution
One lesson in five moves
From the learning path to AI conversation: this is what a day in Xeropan looks like, on the phone.
Real screens from the iOS app, with an English interface.
Step 01: A learning path by topic
Levels, topics and units: every unit has vocabulary, video, grammar and AI conversation, in 7–9 minute lessons.
Step 02: Short, fast-paced exercises
Word order, translation, matching: one tap and you instantly know whether your answer was right.
Step 03: Mini grammar after every answer
It doesn't just say the answer is wrong, it explains why. Sentence by sentence, on the learner's own answer.
Step 04: Conversation with an AI character
In writing or by voice, using the lesson's phrases. To earn the stars, you have to see the conversation through.
Step 05: Vocabulary that sticks
Strong and weak words, a vocabulary meter, and a button that drills exactly the weak words.
In the browser too
The same learning, on a big screen
The web interface is made for school computer labs and the desk at home: the same account, the same progress, with instructions in Hungarian.

KRÉTA integration · IFM
Language learning in KRÉTA, for every Hungarian school.
The IFM module is built on Xeropan and has been part of the school system since 2022. Students sign in with their KRÉTA account, teachers assign work in the interface they already know, and grades go into the e-register. English, German, Spanish, French, and Hungarian as a foreign language.
Sign in with a KRÉTA account
Students sign in to the app with their KRÉTA username and password, or launch it from the KRÉTA app (More → Language learning).
Automatic sync
Students are placed in their own class and group, and teachers see their progress automatically.
Homework and grades
Teachers assign lesson packs from the KRÉTA Digital Collaboration Space or the Classroom interface, and grades go into the e-register.
Free in public education
Free of charge for students in public and vocational education and their teachers. Parents can use it too.

Features
Teacher, coach and game in one app
Every feature serves the same purpose: bringing learners back tomorrow, and making sure they actually progress.
Professor Max's story
A time-travel story across 13 islands: every level is an era, and the stars move Max forward. It's the framework of the curriculum, not decoration.
Video lessons from real content
News, trailers, film clips: the living language as it really sounds, with vocabulary and grammar exercises.
Streaks, leagues, certificates
XP, levels, a weekly league and certificates. The streak survives a missed day, so one bad day doesn't break the momentum.
Personalised review
The app tracks which words are weak and brings them back alongside new material. A placement test and level skipping for faster learners.
English for professionals
11 professional courses, from business English through IT, medical and legal English to hospitality, for companies and institutions.
Start on your phone, continue on your computer
The same account and progress on iOS, Android and in the browser. Sign in with Apple, Google, Facebook or KRÉTA.
