Hey Product Hunt! I'm Josh, founder of SentenceLab. I built this because I lived in Taiwan for years learning Chinese, and hit the classic intermediate wall: I could recognize a lot of words, but in conversation I was hesitant to use them because I wasn't 100% sure on the correct usage and didn't want to embarrass myself. A lot of traditional apps focus on passive recognition (flashcards, multiple choice). But to get more confident using words, I needed active production - actually forming sentences with the vocabulary. With SentenceLab, you practice by creating your own sentences with the new words you are studying, with instant feedback on grammar and naturalness. We just launched a few weeks ago and got our first paying subscriber (not a friend!), which validated that this approach resonates with other learners facing the same struggle. I'd love your feedback on: Does this approach make sense for language learning? What would make you choose this over Anki/HelloChinese/etc? Any features you'd want to see? Happy to answer any questions about the product, learning Chinese, or building as a technical founder!
