Founder building Poly-Puff, an ESL app

About

English teacher and solo indie maker. I built Poly-Puff to give my own students one place to practice real English - grammar-accurate AI feedback instead of guesswork, translation practice tailored to their native language, and exercises that actually adapt to where they are. Currently in closed testing on Android, and always happy to hear from teachers and learners who want in early.
