We deleted the most boring part of learning a language.

Spaced-repetition apps work. The problem was never the studying, it was the setup: typing out word lists, hunting for accurate translations, writing an example sentence for each entry, then fighting the import format so a deck would load without broken columns. By the time a deck was ready, half the motivation was gone.

NextLang exists to delete that step. You bring the words, a topic, or a photo of the page you are studying, and the deck comes back written and formatted for the app you already use. The time you save goes back into the only part that actually teaches you a language: the reviewing.

NextLang is made by Siarhei Hamanovich, a senior engineering manager who has led 130+ engineers, run hundreds of technical assessments, and ships his own products end to end: designed, coded, and maintained solo. He is also learning English and Polish himself, and the generator started as a tool for his own decks before it grew into the product on this page.

One person means no committee between a bug report and a fix, and no feature ships that the builder does not study with himself. If something is off, the support email reaches the person who wrote the code.
