Buy Now for $29.99At Refold, we're focused on getting you to understand REAL Korean — the kind spoken in K-dramas, YouTube videos, and everyday conversation. The biggest barrier to that is vocabulary, and that's exactly what the KO1K Vocabulary Deck is built to solve.
This hand-crafted deck focuses on the words that actually show up in real Korean media. We analyzed over 50 Korean TV shows to find the vocabulary that matters most, then built every card around authentic, naturally spoken Korean.
Korean does have plenty of English loanwords you will recognize instantly — 커피 (coffee), 버스 (bus), 컴퓨터 (computer). We skipped those. Instead, the deck zeroes in on the native Korean words that will not come to you on their own — including more of the high-frequency function words than our European decks carry, because in Korean those little words need real study too. Your study time goes where it counts.
We also added grammar tips — unique to the KO1K — so you pick up essential grammar in context alongside new vocabulary. No separate grammar textbook required. When you finish, you'll have the knowledge and confidence to understand about 85% of Korean dramas and YouTube videos.
For best results, pair the deck with immersion: check out our complete immersion learning guide to see exactly how to combine them.

You do not need to study additional grammar if you use this deck. This deck will teach you the basic grammar you need to get started enjoying Korean TV shows and movies. You can pick up the rest by just listening to and reading a lot of Korean media content.
Yep! It just takes time, energy, and effort. The Korean deck took our team of data scientists, high-level Korean learners, and Korean natives about 150 hours to create. We’ve done the hard work so you don’t have to.
If it’s your first time studying a language, then you probably should.
Duolingo is a language-learning video game. It’s a great way to try out a language to see if you like it and to build a daily habit of engaging with the language.
Unfortunately, it doesn’t get you very far, and definitely won’t help you understand Korean.
Yep! But they have a few problems:
If you want to use a free deck, here’s the best we’ve found: https://ankiweb.net/shared/info/1551455917
They aren’t focused on helping you understand TV shows and casual conversation.
They haven’t filtered out the “easy words”.
They don’t have native audio.
The example sentences (if they even have any) are crowdsourced and usually low quality.
NO! This just builds the initial foundation for understanding Korean. Fluency comes after thousands of hours spent with the language.
