Show HN: I built a Chinese learning app that teaches through sentence patterns

Just wanted to say that the app is really fun to use and I love that you're immediately pushing sentences instead of contextless vocab. I have been developing something in a similar vein as I've gotten jaded by current offerings so it's genuinely encouraging to see others developing in this space!

Hi HN — I built this because most Chinese apps focus too much on isolated vocabulary and not enough on actually forming sentences.

This app teaches Chinese through the most frequently used sentence patterns. You actively build sentences and get instant AI feedback, so you’re practicing production instead of recognition.

It also uses FSRS for scheduling (for both flashcards and audio loops), and includes an AI assistant for help.

No account required to try it.

I’d especially appreciate feedback on:

- Whether the sentence-building approach feels effective

- Clarity of the UI and learning flow

- Anything confusing or unnecessary
