Parlonto is a voice-first language learning app that teaches you to hold real conversations. Every word is introduced in a scenario you'd actually use it in, and you practice by speaking — not tapping.
Built for iOS · Works offline · Your voice never leaves your device
Most apps test vocab in isolation, so you freeze the moment someone actually speaks to you.
Reading and recognizing feels productive, but production is where fluency lives.
Artificial "streaks" reward showing up, not improving.
Parlonto is different. You talk to a person who talks back — in the language you're learning — from the very first lesson.
From recognition to real conversation.
You're shown a new word with a native-speaker audio clip and a quick explanation. Tap to listen, tap the mic, say it back. That's how you meet every new word.
Lock in meaning with quick recall.
You hear a snippet of a realistic conversation, then respond.
A scripted multi-turn conversation with hints that gradually fade. You speak every learner turn. The on-device model grades you against specific criteria.
An open-ended conversation with an AI character that stays in role, speaks only the target language, and responds to what you actually said. Goals are displayed above the input bar and get checked off in real time.
You don't pick your stage — the app picks it for you, per word, based on how well you actually know each one.
Every answer is spoken, not typed. Built-in iOS speech recognition handles transcription.
A modified FSRS spaced-repetition algorithm schedules every word individually — easy words get spaced out, hard ones come back tomorrow.
Every lesson is built from three generated conversations set in a real context, so you're practicing exchanges you'd actually have.
A fine-tuned language model runs locally and grades your responses against explicit criteria — feedback that understands context, not just keywords.
Each session is bounded (target mastery gain or 15 questions max) — no infinite scroll, no streak anxiety.
Earthy olive and cream palette. Built to be the anti-gamified app.
No servers between you and your next conversation.
A fine-tuned 2B-parameter language model runs entirely on your iPhone. It evaluates your responses, plays the character in roleplays, and checks your pronunciation — all without a network call.
No sign-up. No email (except the optional waitlist). No account to delete. Your vocabulary, your progress, your recordings — everything lives on your phone.
Each unit's audio is downloaded once when you add it. After that, everything works in airplane mode: lessons, roleplays, grading, progress tracking.

Describe any situation in plain English — "haggling at a market in Tokyo," "explaining a software bug to a French colleague," "telling a Spanish doctor about a back injury" — and Parlonto generates a full unit: three realistic conversations, a vocabulary list, a full ladder of exercises, and native-speaker audio.
$1 per custom unit. Generated in a minute or two. Yours forever.
All core content, all languages, all features. No subscription. No ads during practice (future ads, if any, will only appear at session-end summary screens). The only paid action is optional custom unit generation at $1 apiece.
Parlonto launches on the App Store June 1st, 2026. Drop your email and we'll send you one message when it's ready — that's it. No newsletter, no drip campaign.
