30-Day Language Challenge

I taught Korean for eight years. I don’t believe an AI can teach you a language — so this does the opposite. You feed it what you already studied, and it turns that into practice. You keep the wheel.

Why this exists

The same thing kept happening to my students: a good lesson, everything understood, and three weeks later it was gone. Not laziness — nothing they studied ever came back in a form they could practice. Most language apps answer that with their own curriculum, and it’s thin and scattered. This one has no curriculum at all. Yours is the curriculum.

What you can put in

Anything you already study. That is the whole point.

• A screenshot of your session in whatever language app you’re using
• A recording of your class — or of the YouTube video you were watching
• A photo of a page in your textbook
• A PDF your teacher sent you
• Or just type the sentences out yourself

Audio, photos, documents, plain text — it all converts into the same thing: dictation, shadowing, vocabulary, grammar drills, a role-play conversation, a podcast version and a quiz, built from that exact material and then scheduled for spaced repetition. Nothing you didn’t bring in yourself.

You’ll probably like it if you

1. Study, but can never keep it organized
2. Have no review notes, and keep forgetting what you learned
3. Want to concentrate in class instead of scribbling notes
4. Study alone and find it hard going
5. Want one grammar point to give you the conversation, the vocabulary, the explanation and the pronunciation check around it — instead of drilling one skill and neglecting the rest

Which languages

You can study English, Korean, Japanese, Chinese, Spanish, French, German or Portuguese. The app itself is translated into ten languages — those eight plus Indonesian and Vietnamese — so you can learn a language you barely know while every instruction, explanation and question stays in your own.

How a day counts

The app shows seven dots at the top of the upload screen. A day turns green only when you’ve done all three of these that day:

1. Upload one thing you studied — a photo, a recording, a PDF, a screenshot
2. Grade one review card in the Practice tab
3. Finish three missions inside a lesson

That’s the whole scoreboard. No honor system, nothing to log by hand.

The schedule

• Day 0 — Sat Aug 22: install day. Upload one thing, nothing else. Review cards only appear the day after you upload, so this is what makes Day 1 countable.
• Day 1 — Sun Aug 23: record yourself reading one sentence in your target language and keep the pronunciation score. That’s your before shot. The Discord invite goes out today too.
• Day 30 — Mon Sep 21: same sentence, same recording. You see the gap.

What it costs

Nothing to try. Everyone gets 7 days free on sign-up, with no card — there’s nothing on file that could charge you.

On top of that, the first 50 people get 30 days free, emailed directly, in the order they sign up. I can’t hand that to just anyone, so there is one condition: check in on at least 20 of the 30 days. If you know you can’t, take the 7 days — no hard feelings.

What I ask

Show up most days. Answer three short check-ins (Day 1, 7, 30). Send a screenshot of your dots on Aug 23, Aug 30, Sep 6, Sep 13, Sep 20 and Sep 21. And tell me when the app gets your language wrong — I taught Korean for eight years, so for Korean I can judge it myself; for the others, you are the only person who can tell me.

iPhone only this round — the Android build isn’t ready. The app went live on the App Store today, so it’s new and you will hit bugs; that’s what the 30 days are for. After the challenge it’s a paid app, with no obligation either way.
