EdgeLingo: AI Language Tutor

Ordering abroad, tomorrow's interview, a meeting with colleagues overseas — the few lines you'll actually need: how many times have you practiced them?

EdgeLingo lets you speak whenever you want. An AI plays the barista, the interviewer, the landlord, and every line you say comes back with a more natural way to put it — then it gets you to use that line in your next conversation. The AI runs on your iPhone: download the models once, and you can practice without a connection after that. Want a bigger model? Turn on Cloud AI.

■ Follow a journey
• 6 journeys, 20 stops, 60 lessons: a trip abroad, eating like a local, a new job, living abroad, making friends, and handling trouble
• Every lesson has four steps: key phrases → shadowing → conversation → your fixes. About 10 minutes each
• Tell it where you're going, for how long and with whom, and the conversations follow your trip. Each stop has a challenge and stars, and the map grows as you go

■ How you practice
• 84 real scenarios: airport check-in, ordering food, job interviews, reporting a repair to your landlord… The AI stays in role, asks follow-up questions, and every scene has clear goals that get ticked off as you hit them
• A more natural line for every sentence: grammar and word choice, learned in context instead of from a list
• Corrections come back: the things you keep getting wrong, the AI creates a chance to say right next time
• Today's practice: shadow a few lines, have one conversation, hear your last corrections again — ten minutes a day is progress
• Tap to look up: tap any word or phrase in a conversation to see what it means and save it to your word bank — the AI works the ones you haven't used yet into later conversations
• Widgets and Siri: your streak and today's practice on the Home Screen and Lock Screen, and Siri can start a session for you
• AI placement: speak for a minute to get a starting level; from there it adjusts to how you actually do
• Build your own scenes: describe one in a sentence, or photograph a menu or a sign
• Pronunciation scores (English, Japanese, Korean; optional): see which sounds need work after you shadow
• 16 practice languages: English, Japanese, Korean, Spanish, French, Italian, Portuguese, German, Chinese, Vietnamese, Turkish, Polish, Indonesian, Hindi, Greek and Latin (experimental). The first 12 also work as the app's language, so explanations come in your own

■ Why EdgeLingo
• Pay once: it's yours. No subscription, no account — Cloud AI is included too, with a daily fair-use limit
• Works offline: the AI and voice models download the first time you open the app; after that, a flight or a trip without a SIM changes nothing. With Cloud AI on, it falls back to the on-device AI whenever there's no signal
• Private: no ads, no tracking, and your practice stays on your phone by default. With Cloud AI on, only text is sent (plus a photo, if you say yes, when you build a scene from one) and nothing is stored; with pronunciation scores on, shadowi
