Your personalised language learning system
You've seen the word. You've studied it. You might even recognise it. But when it's your turn to speak, it disappears.
FluentDeck helps you learn the words you actually need, remember them, and use them until they start coming naturally. Because that's fluency.
What do you want to learn?
e.g.
Custom stories built from your words, your interests, and your level.
Spaced repetition and automatic pacing use progressive active recall, so it grows with you as you learn.
Stories, fill-in-the-blanks, dictation, and sentence use.
So the words you've studied don't just look familiar. They start becoming words you can actually say.
FluentDeck takes the vocabulary in your deck and builds short stories around your level and interests, so you're not trying to memorise isolated words with nothing attached to them.
You see the words in context. You hear them. You see how they fit with the language around them.
Why it works: learning vocabulary in meaningful context creates more associations around a word than studying it in isolation, giving your brain more ways to recognise and recall it later.
Luca marchait lentement dans la forêt, les feuilles tombant doucement autour de lui. Il aimait la paix de la nature et le son des oiseaux dans les branches.
FluentDeck uses spaced repetition to decide when each word should come back.
Words you're learning need more attention. Words you know well appear less often. And if you fall behind, FluentDeck holds back new words until you've caught up.
You don't have to plan your reviews or figure out what to study next.
Open FluentDeck and your session is ready.
New word
la forêt
feminine nounthe forest
« Les arbres de la forêt étaient immenses et anciens. »
How did it go?
Flip the card
The vocabulary you're learning comes back in short stories, fill-in-the-blank exercises, dictation, and sentences you write yourself.
So you're not only getting better at recognising la forêt when FluentDeck shows it to you. You're practising remembering it without the answer in front of you, and using it inside real language.
Session words

Free for 7 days · no credit card
FluentDeck is for anyone who wants to actually use the language they're learning.
Maybe you're moving abroad. Learning for work. Studying for school. Getting ready for an exam. Or just want to be able to have a real conversation without your brain suddenly forgetting every word you've ever learned.
FluentDeck gives you one place to build the language you actually want to learn. Tell us what you're interested in and we'll build a personalized vocabulary deck around it.
Learning Italian for your new life in Italy? French for work? Medical sales? The vocabulary you need for a kitchen? We can build that too.
And we don't believe language should live on a flashcard.
You learn words through examples, audio, writing, sentences, and interesting stories that put them into context. As you learn, FluentDeck helps you move from recognizing a word → writing it → using it → recalling it when you actually need it.
Because the point isn't to know more words.
It's to have more words available to you when you're living, working, speaking, and thinking in another language.
That's what we're building FluentDeck for.
We can't promise you'll never forget a word. That's not how memory works.
But FluentDeck is designed around how your brain actually creates and retrieves memories, rather than asking you to memorize words in isolation.
We've all done the endless studying where your eyes glaze over, only to completely freeze in a real conversation. It's about working smarter, not harder. It's how you study, not just how much.
Here's how we approach it:
Spaced repetition. We bring words back around the time you're likely to forget them, so you're actively retrieving them instead of simply looking at them again and again.
Custom context. We anchor words in stories and context matched to your level and interests, giving your brain more meaningful connections to work with.
Leveling up. Your flashcard grows with you. First, you get to know the word. Then you write it. Once you're comfortable, you use it in a sentence and in fill in the blank stories.
You're using active recall throughout, actually pulling the word from memory instead of simply recognizing it.
The goal? To be able to say what you want to say when you want to say it, instead of dumbing yourself down because you forgot a word or looking it up again... for the 10th time.
Simply, no.
Flashcards are good at helping you learn what a word means. But knowing a word when you see it isn't the same as having it come to you when you're actually speaking.
That's the frustrating part. You've studied the word. You recognize it. You might even understand it perfectly in a sentence. Then you're in a conversation and suddenly you're thinking, "What is that word again?"
We built FluentDeck to help close that gap.
That's why your words don't just stay on a flashcard. You see them, recall them, write them, use them in sentences, and encounter them in stories and listening practice. The more ways you work with a word, the more connections you build around it.
So what does that mean for you?
When you're actually speaking, writing, working, traveling, or living in your new language, the words you've learned are there when you need them.
You don't just recognize the word.
It's just there.
Your vocabulary shouldn't be scattered everywhere.

FluentDeck gives you one place to collect the vocabulary you actually want to learn, whether you build a custom deck, start from a vetted frequency list, paste in your own words, or import what you already have.
You choose the words. FluentDeck builds the deck, keeps everything organized in one place, and tracks what needs to come back next, so you can spend your time learning, not managing your learning.
You just open it and learn.
Absolutely.
FluentDeck isn't just for learning how to say "hello" and "apple."
Because you decide what you want to learn, it can grow with you. Whether you're picking a language back up, preparing for an exam, or learning highly specific vocabulary for work, your decks and stories adapt to your level and interests.
You don't have to start from the beginning just because you're starting with FluentDeck.
That's exactly why we let you decide what goes into your decks.
You can build around the vocabulary you're missing rather than starting over with words you already know.
Already know the basics? Skip them. Need a deck for a specific topic? Build one. Want to focus on words you keep forgetting? That's what FluentDeck is for.
Yes. That's one of the things we're most excited about.
You aren't limited to a generic list of words someone decided every language learner should know.
Tell FluentDeck what you're interested in, what you're studying, where you're going, or what you're trying to do in the language, and build your learning around that.
Because the words you need to live your life aren't necessarily the same words someone else needs.
You don't need hours. You decide.
You choose how many new words you want to learn, setting your pace and FluentDeck handles the pacing.
Miss a few days? No problem. New words wait until you're caught up on your reviews, so the pile never gets out of hand.
Have five minutes? Do five minutes. Have longer? Keep going.
Practice on your commute, waiting in line, or whenever you have a few spare minutes. It's designed to fit into your life, not take it over.
You don't get punished for being human.
If you miss a few days, FluentDeck pauses new words until you've caught up on your reviews.
That means your backlog doesn't keep growing while you're trying to catch up.
Life happens. Your language learning app shouldn't make you feel worse about it.
Yes, absolutely! Get fluent on the go, reviewing your words and stories on your phone wherever you are.
Vocabulary is where we're starting because words are the building blocks you need to understand and express yourself.
But FluentDeck is being built around something bigger than memorizing word lists.
The goal is to help you build a language you can actually use through vocabulary, context, writing, listening, and eventually more ways to practice and express yourself.
Yes.
We didn't want to build another app that simply makes flashcards look prettier.
The way FluentDeck works is informed by research on memory and learning, including spaced repetition, active recall, and learning through meaningful context.
