Patter: AI Language Chat
Spanish, French & German Tutor
Free · In‑App Purchases
Tired of cartoon mascots guilt-tripping you? Tired of tapping pictures of apples in a language you've been "learning" for two years? Patter is for grown-ups who already know some of the language — and just need a place to actually use it.
FOR LEARNERS, NOT BEGINNERS
Patter isn't where you start from zero. It's where you go after the basics, when you know enough words to form a sentence but freeze the moment a real conversation begins. If you can read a menu, introduce yourself, or follow a simple text — you're ready.
This is the practice you've been missing: low-stakes, real conversations, with no one watching.
A DIFFERENT KIND OF LANGUAGE APP
No mascots. No leaderboards. No fake urgency. Just real conversations with AI personas who text like actual people — and in-the-moment corrections that help you get better without making you feel bad.
• Conversations, not drills. Chat with AI personas about food, travel, work, weekend plans — whatever you'd actually talk about.
• Corrections that teach. When you slip up, you get a quick, in-context fix with a reason. No buzzers, no hearts lost, no shame.
• Quiet progress. Daily goals and streaks exist if you want them, but they're a tool — not a whip. Skip a day. The app won't email your family.
• Familiar interface. Looks like the messaging app you already live in. No tutorials required.
• Private by design. Conversations stay on your device. No accounts, no ads, no data sold.
FEATURES
• Multiple AI personas with distinct voices and topics
• In-the-moment grammar and word-choice corrections with brief explanations
• Translation assist when you're stuck — peek, then try again
• Voice dictation directly in the chat composer
• Vocabulary list — browse every word and phrase you've practiced, organized by when you learned it
• Optional daily goals and streaks
• Conversation history you can revisit
• Bring-Your-Own-Key to connect your own AI provider
LANGUAGES
Spanish (Spain and Mexico), French (France and Canada), Portuguese (European and Brazilian), German, Italian, Japanese, Mandarin, Korean, Russian, Romanian, and English (American and British).
WHO IT'S FOR
• Adult learners past the absolute-beginner stage
• Travelers who want to actually hold a conversation
• Heritage learners reconnecting with family languages
• Returners brushing the rust off a language they once knew
• Anyone who'd rather text than drill
A NOTE ON THE AI
Patter is powered by AI, and AI sometimes gets things wrong — a weird phrasing, an odd correction, the occasional confidently incorrect answer. We're working on it.
But hey, don't we all make mistakes? Use Patter as practice, not as gospel. When something feels off, trust your teacher, your textbook, or a native speaker over the bot.
Open Patter. Send a message. Learn the way adults learn anything — by doing it, quietly, on your own terms.
A NOTE ON PRICING
Patter is free to download. Its AI features — persona conversations, grammar corrections, and translation assist — run on credits and require an in-app purchase.
• Monthly subscription: choose a plan (Day Tripper, Explorer, Resident, or Expat Family) for a refill of credits each month. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the period. Manage or cancel anytime in your App Store account settings.
• Credit top-up: a one-time purchase to add extra credits.
• Bring-Your-Own-Key: a one-time unlock to connect your own AI provider key — then no Patter subscription required.
