Griing is an AI English coach that remembers the expressions you learn and brings them back on a spaced review schedule. Every day you get one short session at your level: warm up with review, pick up new expressions, listen, shadow out loud, and check yourself with a quick quiz. Everything you learn goes into your expression bank, and your coach brings it back for review over the following days. No pressure, no classroom. Just a few minutes a day that add up. • A daily session matched to your level, with a placement test to start • Spaced review: your coach schedules expressions to come back for review • Listening and shadowing so you practice out loud • Free Talk: hold a real conversation with your coach and see your sentences polished as you go • Build a streak and watch your level grow • Available in English, 한국어, 中文, 日本語, and Español Griing's coach is an AI, not a human. For ages 18 and up.
