A Ukrainian couple created Iterum, an app for learning languages from articles, books and videos

Ksenia Snitko and Vlad built the Iterum app, which translates unfamiliar words from what you read or watch and helps you remember them, using Claude.

✨ How Iterum came about

Ksenia Snitko works as an EdTech marketer. When she went back to learning English intensively, she and her husband Vlad, a developer, decided to build a tool that suited her needs. That is how the Iterum app appeared. According to Ksenia, the Claude model helped them build it quickly.

Ksenia said she had a solid B2 level but wanted to read harder articles and books without forgetting new words. She wrote that she wants to read 2–3 articles on Substack or Medium a week, watch YouTube videos, and practice words instead of endlessly scrolling a feed.

As Ksenia noted, there are many language apps on the market, but in her view there is no ideal mix of method and simplicity, and some products have extra features or prices that do not match what they offer.

📌 What Iterum can do

The main idea of Iterum is to learn words together with the text or video they come from, not from separate lists. You can read articles by link, open books in EPUB and PDF formats, and watch YouTube videos with synced subtitles. Books can be read inside the app or through the Google Chrome browser extension.

When you tap an unfamiliar word or phrase, Iterum translates it based on the specific sentence. The app also determines the level according to the CEFR scale and how often the word is used.

Word review is not based on a simple "know / don't know" button. The system analyzes how correct and fast your answers are and builds its own review schedule. There are also AI exercises created from the words you have saved.

🔹 Languages, price and launch

Currently you can learn English, Spanish, French and Polish, and German and Italian, which were added recently.

Iterum uses a Freemium model. Basic trainers, saving materials and creating your own collections are free. Advanced personalization and extended AI features are available with the Iterum Advanced subscription.

The app is available on the App Store for iPhone and on Google Play for Android. Beta testing started in early September, and the official release followed at the end of that month. According to Ksenia, 5,000 users installed the app in the first 5 weeks, and in late October it reached 25th place in the Ukrainian App Store.
