I've been working on GrokVocab (https://www.grokvocab.com), an app to improve vocabulary without flashcards or memorization.

Everyone knows reading is the best way to build vocabulary, but many avoid it and turn to flashcards or spaced repetition because long texts can feel overwhelming, and they often have to refer to a dictionary.

This app gives users short, engaging passages focused on comprehension. While reading, users guess word meanings from context and find out whether they got it right by answering a few questions below. I believe this will be helpful for people who haven’t had much success with popular vocabulary learning methods.

I shared it on HN earlier (https://news.ycombinator.com/item?id=44543063), but it didn’t get much attention. If you're interested in novel learning methods or vocabulary, I’d love your feedback.

P.S. Login is required since the app uses LLMs to generate interesting passages. You can register with any non-existent email if privacy is a concern.
