Show HN: Read and Echo – Turn any text into structured language practice

Hey HN,

Read and Echo is a small web app for people studying a foreign language with real texts. You give a short brief (topic, level, languages); the app gives you a prompt you can run in any chat model; you paste the JSON back once. After that you get sentence-by-sentence reading with translations, word glosses, saved vocabulary, and comprehension questions tied to that passage—not a generic word list drill.
