QuantumMind AI LLC · New Jersey · product: Aurion Lingua at lingua.qmai.dev. Last updated 21 August 2026.
Lingua is for people 13 or older. It is a language-learning companion, not a dating product, not a celebrity impersonation, and not a child-directed service. Do not use a child voice or ask the companion to role-play a minor.
You talk with an owned companion (Nova, Mei, Rafael, Kenji). Speech, hearing, and the 7B brain run on QMAI infrastructure. We do not send your words to third-party AI vendors. You may add Lingua to your phone home screen from this website. We do not sell it on Apple’s App Store or Google Play.
You can talk on a trial without an account. Saving progress uses a QMAI cookie after: (1) Stripe checkout, which is a login, (2) an email sign-in link, or (3) Google when that connection is enabled. Paying does not require a separate password. You can sign out on a device; local words stay until you erase them.
Subscriptions are billed by Stripe. Founding is $7/month for the first 50 people, then Standard $9.99 and Pro $19.99. Cancel any time in the Stripe customer portal. Cards never touch QMAI servers. Refunds follow the live QMAI refunds page.
Profile, vault, and streaks start on this device. If you sign in, we store an opaque copy on our droplet so another phone can restore it. We do not sell conversations. We do not use your speech to train public models. Export and erase are in the You tab.
