AI voice tutor · 12 languages

Live a thousand lives.
In a new language.

You don't drill flashcards. You talk your way through stories — and the story talks back, out loud, in the language you're learning.

How it works

Just talk. The story does the rest.

No menus to learn, no grammar tables to memorize. Press, speak, and the conversation carries you.

Of course! Anything to go with it?
  1. 1

    Speak.

    Press and say it out loud, in the language you're learning. Beginner or fluent — it meets you where you are.

  2. 2

    The story answers.

    A character replies in voice and in character — a shopkeeper, a detective, a friend. You talk back. The scene keeps moving.

  3. 3

    The words come back.

    Gentle corrections when you want them, and the vocabulary you learn quietly returns in your next adventure — right before you would have forgotten it.

Two ways to play

A whole world, or just a quick chat.

Same voice tutor underneath. Two very different moods.

Step into a life.

Play a character in a story — a spice trader on an old sea route, a reporter in 1920s Berlin, a traveler in a city that does not quite exist. Words you learn in one life resurface in the next. Spaced repetition, disguised as storytelling.

  • Curated lives, or invent your own
  • Scenes that branch on what you say
  • Your vocabulary carries across stories
Practice GigaDuck with a laptop

Or just rehearse.

Spin up any scene in seconds — a job interview, ordering at a restaurant, a friendly argument — and practice with a patient AI tutor who never sighs and never gets tired of you.

  • Describe a scene by voice or text
  • Set the speed and the difficulty
  • Replay, correct, try again
Adventures

One duck. A thousand lives.

Every life is a new vocabulary, a new register, a new world to talk your way through — and the words you pick up in one follow you into the next.

Meet a word as the chef, hear it again as the surfer. That is how it sticks.

Twelve languages

Spoken, not typed.

Learn any of them — and speak from the first lesson. Here's hello in all twelve. More on the way.

Hello English
Quietly, in the background

Learning, without the homework feeling.

The teaching happens between the lines, while you are busy having a conversation.

Corrections that do not nag

A small badge when something could be better. Tap to see the fix and why — or ignore it and keep talking. You set how picky it is.

Stuck? Ask for ideas

Blanking mid-sentence is normal. Tap once for a few things you could say next — with translations — then say one in your own voice.

It remembers for you

Every word you use is quietly tracked and brought back at the moment it is about to fade. No flashcard chore — the review hides inside the next story.

A weekly look back

Streaks, minutes spoken, words met. Enough to feel the momentum — never a guilt machine. A bad week is just a quiet one.
