Stop freezing when it’s your turn to speak Spanish.
The words you save while reading become your flashcards, and the words you can finally say out loud are the ones that count. One connected loop, not three apps that don’t talk to each other.

Why Fluir exists
Duolingo got you started, but you’re not yet conversational.
The plateau you’re in isn’t a motivation problem. The activities that actually move you from beginner to conversational require immersion — reading native content, tracking words in context, and speaking. Today that means juggling three separate apps that don’t share what you know.
The one idea
One vocabulary graph. Every word flows through it.
You can save words new to you while reading articles and speaking to Lucía in voice notes. Flashcards then help you remember those words. And every word you save feeds back into the next article, the next card, the next conversation.
Read native Spanish — tap to save new words.
Your saved words become the flashcards.
Say them aloud — and save new ones Lucía uses.
Three features, one loop
Everything you already do — finally connected.
Reader
Read real Spanish, at your level
Native-level articles pitched to your personal 90–98% comprehensible zone. Tap any word to save it, or have the whole piece read aloud by a natural Spanish voice.
Refresh
Flashcards from your own reading
Every card is a word you chose to save—never a generic deck. Each one still carries the authentic sentence where you first met it. Proven spaced repetition, so it sticks.
Conversation
Say it out loud to Lucía
Voice-first, turn-by-turn conversation with an AI tutor briefed on your recent words and reading. It helps when you’re stuck and corrects gently—never overwhelming.
How you actually improve
Your level rises because your vocabulary does.
Fluir doesn’t quiz you up a ladder or hand out fake “level-up” badges. It grows the one thing that truly moves you from B1 to B2 — the Spanish words you can recognise and say — and quietly keeps everything you read at the exact difficulty where learning is fastest.
Vocabulary coverage of each level’s core Spanish — not a self-assessed score.
You’ll see something like “~4 months to B2 at your pace” — an honest example from the real in-app projection.
Every word compounds
Each saved word moves through your graph — met → known → said out loud. That growing vocabulary is your real level.
Tuned to you
As your vocabulary grows, Fluir serves articles you understand ~95% of — never too easy, never a wall. Difficulty rises with you, automatically.
Measured honestly
We track your coverage of the real CEFR vocabulary for each level (Instituto Cervantes, Cambridge) and show an honest pace that slows if you do. No inflated numbers.
Value first, always
The whole loop is free to try — no card.
No card at signup. No demo. Read a complete, narrated article and tap to save words, do a real round of flashcards built from those words, then spend a minute talking with Lucía. Feel the whole loop for yourself before you decide anything.
