I have tried many different tools to improve my vocabulary but most of them feel like simple games rather than actual education. Recently I checked out https://promova.com/page/ai-language-learning-app to see if the modern approach is any better. The lessons seem to have a real-life focus which is much more helpful than learning random words that nobody uses in daily conversation. It is a decent option if you want something structured but flexible enough to fit into a busy work schedule without feeling overwhelmed by grammar rules.
