AI speaking practice for iPhone

Studied a language but freeze when you speak? Talk your way through Capy Town.

Order a drink, ask for directions, check in to a hotel. You get each errand done by speaking with a town resident played by AI. When you slip, the wrong part turns into a block and you swap in the right one. It's an AI on the other side, so try as many times as you like.

Coming soon to the App Store

  • One-time purchase
  • No account needed
  • AI conversations need a connection

iPhone, iOS 17 or later. The App Store shows the current price for your region.

CapyTalk's town map: the Port Station scene with the travelling capybara at the top, and below it the path of lessons such as greetings, asking for directions and buying a ticket, several already marked with stars.

Your first turn

Say one line. The wrong block is swapped on the spot.

This is the first lesson in Café Market, practised here in Japanese with notes in English. Near the end, the fox barista asks whether it's for here or to go.

GoalsFox the barista

  • Order a drink (done)
  • Say which size you want (done)
  • Say for here or to go (done)

Fox the baristaLサイズですね。店内で召し上がりますか、それともお持ち帰りですか。Translation: Large, got it. Will you have it here, or take it away?

You saidここに飲みます。

ここYou said にchanged to で飲みます。

Use で to indicate the location where an action takes place.

Fox the baristaはい、かしこまりました。店内でLサイズのアイスコーヒーですね。少々お待ちください。Translation: Certainly. One large iced coffee for here. Just a moment, please.

You do
Say one line into your iPhone. You can type instead when you can't talk out loud.
You see
Your sentence split into blocks, the wrong block replaced by the right one, and a one-line note. The character keeps the conversation going.
You keep
The sentence comes back in the review step after the conversation, and it stays in your travel journal.

The character's lines, the correction and the note are the AI's actual output from a test conversation on 8 October 2026. The screen is redrawn from the app and the English translations were added for this page. This is an illustration, not an interactive trial.

How a lesson works

Every lesson is the same loop: repeat, speak, fix

  1. 01

    Repeat

    Each lesson starts with the three phrases you'll need most in that scene. Listen, then say them out loud. The words that were heard correctly turn green.

    What comes nextWhen the conversation starts, you already have three lines ready to use.

  2. 02

    Speak

    The resident speaks first. A short list on screen shows the three things to get done, and each is ticked off as you manage it. Tap “Show translation” if you missed a line. If you're stuck, there are three levels of hints, and the last one lets you ask “How do I say…?” in your own language.

    What comes nextA slip turns into blocks right under your sentence, with the right block swapped in.

  3. 03

    Fix

    After the conversation, the corrected sentences come back one at a time. This time you put the right block in place yourself.

    What comes nextThen you earn the stamp. The fixes from that session stay in your travel journal, which keeps your 200 most recent conversations, so you can look back or practise the same lesson again.

The question we hear most

Your voice stays on your iPhone. Only text is sent.

Speech recognition runs on the device, using the recogniser built into iPhone. Your audio is not uploaded, and the app does not save recordings.

So that the character can reply and your sentence can be checked, the recognised text is sent, with the last few lines of that conversation, to our server and from there to Google's Gemini. Our server does not store conversation content.

Stays on this iPhone

  • Your voice (no recording is saved)
  • Conversation history and fixes, for the 200 most recent conversations
  • Progress, streaks and stickers
  • The name or nickname you enter

Leaves your iPhone

  • The text of each line you say, plus the recent lines of that conversation: to our server, then to Google Gemini
  • The lesson, practice language and level, so the character knows which scene it is
  • Apple's proof of purchase, to confirm you bought the app. Our server discards it after checking and keeps only a hash that can't be used to look up who you are; records such as usage counts are filed under that hash

Three limits to know about

Anything you say in a conversation, including your name, is sent as text. Text that reaches Google is not used to improve Google's products, but Google keeps it for a limited period to detect abuse. If your iPhone doesn't support on-device recognition for a language, the app asks you to type. It does not switch to uploading audio.

  3. Conversation screen: the café scene with the fox barista. The player's sentence is shown as blocks with one particle replaced, above the note “The thing you ask for takes を, not が.” The barista then asks about the size.
    03ConversationA slip turns into blocks under your sentence: the wrong block is swapped for the right one, with a short note. The barista carries on.
  4. Review screen: the first sentence already has the right block in place. The second has a gap, with two blocks to choose from, に and で.
    04ReviewAfter the conversation, the corrected sentences come back. Put the right block into the gap.
  5. Stamp earned screen: a coffee cup stamp, three stars, and counts for minutes talking, sentences said and sentences fixed.

Who's behind it

A team you can reach

CapyTalk is made by a team in Taiwan, the same team behind Capybara Korean.

The example sentences and scripted lines in the lessons were written and cross-checked by AI. They have not been reviewed by native-speaking teachers. Corrections and notes during a conversation are also generated by AI on the spot, so now and then a mistake is missed or a note is imprecise.

FAQ

Before you buy

Do I pay again after buying?

No. CapyTalk is a one-time purchase: you pay once on the App Store, and the app has no in-app purchases and no ads. Prices vary by region, and the App Store shows the current price for yours.

Do I need an account?

No. There is no sign-in and we never ask for your email address. The purchase goes through your Apple Account.

What works without an internet connection?

AI conversations, live corrections, translations and “How do I say…?” need a connection. Key phrases, repeating, review and the travel journal still work without one.

Is there a limit on AI conversations?

Yes. To keep a one-time purchase sustainable, conversations have a daily and a monthly limit: currently 60 turns a day and 600 a month. One line from you and one reply from the character is a turn; “How do I say…?” also counts as a turn.

Translations are counted separately, 150 a day, and don't use up turns. The daily limit resets at 00:00 UTC, and the app shows how many turns are left once you are down to the last 10 for the day. After you reach a limit, key phrases, repeating, review and the journal keep working. These numbers may change, and this page will be updated when they do.

Can a complete beginner use it?

You can start with the first lesson at Port Station: choose “Just starting” and the characters use very short sentences, and Japanese, Korean and Chinese come with a reading aid.

But CapyTalk doesn't teach alphabets, kana or grammar. It's practice for people who have studied a little and want to start speaking.

Are the AI's corrections always right?

No. Corrections and notes are generated by AI. It can miss a mistake, and a note can be imprecise. That's why, when nothing was changed, the app says “Nothing to fix here” rather than “Correct”. If a correction looks wrong, please email us.

Is there an iPad or Android version?

Right now CapyTalk is for iPhone only, on iOS 17 or later.

Can I get a refund?

Purchases and refunds are handled by Apple. You can request one at reportaproblem.apple.com.

What happens to my progress if I delete the app?

It's deleted. Progress and history are stored only on your iPhone. There is no account and no cloud sync.

Start with one “Hello” at Port Station

One-time purchase, no in-app purchases, no ads. iPhone, iOS 17 or later.
