Four channels, one vocabulary set

01

Monthly Anki deck

CEFR-calibrated sentences with native audio. This is where you learn the words — spaced repetition builds durable memory traces one card at a time.

02

Weekly reading

A short article in your target language built from your vocabulary, with comprehension questions. This is where you learn to read the words in context.

03

Vocabulary quiz

Questions on the web, ready when you are. This is where you test yourself — retrieval practice that strengthens what you've studied.

04

AI text tutor

Daily SMS conversation in your target language with gentle corrections. This is where you learn to produce — turning passive knowledge into active use.

Plus a monthly progress report with quiz accuracy, reading comprehension, engagement trends, and a recommendation for next month.

Questions

Do I need Anki?

Yes — Anki is free on all platforms. Each month you'll receive an .apkg file to import. Deck sizes are calibrated to your CEFR level (60 sentences at A1, up to 250 at C2), and each month's import merges into your existing deck — your review history is always preserved. If you don't use Anki, the weekly articles, vocabulary quizzes, and AI tutor still work independently.

What languages are supported?

We support 22 languages: Spanish, French, Japanese, German, Italian, Korean, Mandarin, Portuguese, Arabic, Russian, Hindi, Dutch, Swedish, Turkish, Greek, Indonesian, Tagalog, Norwegian, Danish, Vietnamese, Polish, and Swahili.

What CEFR levels do you support?

A1 through C2 — all six levels. You set your level during onboarding and we tailor sentence complexity, article length, and quiz difficulty accordingly. The monthly report will recommend a level-up when your data says you're ready.

What's the weekly reading?

Every Monday you receive a short article written in your target language, built from your current deck vocabulary. It comes with 3 comprehension questions you can answer with one tap. The article length scales with your level — short paragraphs for beginners, longer pieces for advanced learners.

How does the AI text tutor work?

It's an opt-in feature via SMS. Each day at your chosen time, you receive a conversation prompt tied to your current vocabulary. Reply in your target language, get gentle inline corrections, and continue for 3–5 exchanges. Set it up during onboarding or in account settings.

Can I cancel anytime?

Yes. Cancel from your account settings and your subscription ends at the next billing date. No questions asked, no friction.

What if I fall behind on quizzes?

Nothing bad happens. There are no streaks to break. The monthly report notes your engagement trend and may suggest adjusting difficulty or topic mix — that's it.
