lang.ai
practice english by talking
lang.ai turns english practice into a real conversation. You pick a scenario — a job interview, ordering food, planning a trip, making friends, a doctor visit, apartment hunting — and an AI character plays the other side. You speak your replies out loud; the browser transcribes them in real time, so you're practising the part that actually matters and the part most apps skip: talking.
After each thing you say, lang.ai quietly acts as a tutor. It flags grammar and word-choice slips, shows a corrected version and a more natural way to phrase it, and leaves one short, encouraging note — without ever breaking character. No partner to schedule, no one to feel self-conscious in front of, no payment. Just reps and feedback, one conversation at a time.

great — "no sugar" is perfect; native speakers often drop "and".

nice instinct — use the present perfect ("i've been") for things that started in the past and continue now.
