Ready-made flashcard decks teach you the words someone else decided you need. Half of them you will never meet in anything you read. The words that actually stay are the ones you ran into in a real text, wondered about for a second, and then met again two days later.
Fluenvo builds your flashcards from exactly those texts. You read or work through something in Spanish, the words you want go into your personal dictionary, and the app brings them back for practice at the right time.
Start with a text you are reading right now →There are three ways, and you can mix them.
From a text or a video. While you read a text or follow a transcript in Fluenvo, tap a word. You get a translation right there and can add the word to your dictionary in one more tap. The word arrives with the meaning that fits your text, not a list of ten possible translations.
From your exercises. When Fluenvo builds exercises on a text, the vocabulary it picks from that text is saved for you automatically. You do not copy anything anywhere.
By hand or from a file. Add a single word yourself, paste a list with one "word — translation" per line, or import a file from Anki, Quizlet, CSV, XLSX or TXT. If you already built a deck over the years, it does not go to waste.
If you add a word you already have, the app asks whether it is the same word or a different one. The same word gets the new translation added to it. A different word becomes its own card. Your dictionary does not fill up with copies.
Each entry shows the Spanish word, its translation, how many times you have seen it, and a button to hear it. Open an entry and you can swap its direction. At the top of the screen you see the whole picture at a glance: how many words you have in total, how many you know, how many you are learning and how many are still new. A search field helps you find a word when the list gets long. If some words came without a translation, the app flags them and fills them in from its dictionary, because a card without an answer cannot be practiced.
Here is what a few real entries look like in the Spanish-to-English dictionary: arce with the translation "maple tree", destreza with "dexterity", roncamente with "hoarsely", and the phrase aprovechar el tiempo with "make the most of the time (seize the time)". Phrases are saved the same way single words are, so an expression you liked in a text stays whole instead of falling apart into separate words.
Looking at a card is the weakest kind of review. Fluenvo gives you five modes, each in both directions, Spanish to your language and back:
Switching between modes keeps the same words from feeling like the same drill.
A word you answered well returns after a longer pause. A word you missed returns sooner. The intervals grow as you get a word right, so you spend your time on what is slipping away, not on what you already know. You do not build a review schedule by hand.
A word from a text you read already has a story: the paragraph, the topic, the moment you needed it. That is what memory holds on to. A word from a random deck has nothing to attach to. When the same word then shows up in the next text you work on, you recognize it, and that second meeting is the one that makes it permanent.
It also keeps your vocabulary honest. A dictionary made of your own texts reflects what you actually read and want to understand, at the level you actually read at.
Read or work through one text. Save the words you really want to keep, not every unfamiliar word on the page. Do a short practice session the next day. When a new text brings back words you already saved, you will notice, and that is the sign the system is working.
Learners who read, watch or listen in Spanish and want their vocabulary to follow what they read. People who already have flashcards in Anki or Quizlet and want them in the same place as their texts and exercises. Anyone tired of decks that do not match their level.
Do I have to make the cards myself? No. Tap a word in a text and it goes in, and the vocabulary from your exercises is saved for you.
Can I bring my old decks? Yes, from Anki, Quizlet, CSV, XLSX or TXT, or by pasting a list.
Does it work in both directions? Yes. You can practice Spanish to your language and your language to Spanish.
Can I hear the words? Yes, each word has a pronunciation button.
