EdgeLingo

Your AI language partner — buy once, yours forever.

EdgeLingo is a speaking-practice app whose AI runs entirely on your device: real scenario conversations, natural-phrasing corrections, and spaced-repetition review of the phrases worth keeping — fully offline, so your voice and conversations never leave your phone.

■ Why it's different

• Pay once: one purchase, yours forever. No monthly plan, no per-message fees, no account

• Fully offline: once the model is downloaded, practice on a flight, in the subway, anywhere without signal (type or speak — both work)

• Truly private: we collect no data at all — no analytics, no ads, no tracking

■ What you get

• Real conversations: 75+ scenarios (airport check-in, ordering food, job interviews, handling a car accident…) with an AI that stays in character, asks follow-ups, and gives you clear goals

• Phrasing fixes: see a more natural way to say every line — grammar and word choice, learned in context

• Chunk review: reusable phrases are pulled from each chat and brought back with spaced repetition so they stick

• Stuck? One tap gets you three ways to keep the conversation going

• Custom scenarios: describe a scene — or snap a photo — and get a practice scenario built for it

• Nine languages: English, Japanese, Korean, Spanish, French, Italian, Portuguese, German, and Chinese — guided in your native language

■ Device requirements

Requires an iPhone 12 Pro / 13 Pro family device, or any iPhone 14 or later (6GB+ memory), with iOS 26 or later. AI models come built into the app — fully offline right after installation.

Pay once. No subscription. Practice anytime — no pressure.
