What is Fluido
Most apps teach you words. Fluido teaches you to speak. Every lesson is tuned to your level and to who you are, so the Spanish you learn is the Spanish you'll actually use.
A placement test sets your CEFR level. Lessons, tests, and reading adjust as you climb from A1 to C1.
Read sentences aloud into your mic. Fluido scores your pronunciation word-by-word and shows exactly what to fix.
Five ways to practise talking, by voice or by text. A real model answers, and every Spanish line it writes is checked against your level first. When it cannot be reached, the built in tutor takes over and the screen says so.
How it works
A clear path, not a pile of flashcards.
Your job, city, hobbies. Lessons use real examples about your life, so you can talk about yourself from week one.
A short adaptive quiz finds your level so you start exactly where you should.
Grammar, verbs, vocab, reading, listening, and live speaking, all woven together at your level.
End-of-level tests unlock the next stage. You only advance when you're truly ready.
The path
Every CEFR level is a world with its own goals, grammar and milestones. 142 of the 142 lessons on that path are written and playable today, and your dashboard shows the same two numbers.
First words, present tense, survival Spanish.
Past & future, daily routines, real conversations.
Opinions, stories, the subjunctive begins.
Debate, nuance, idioms, fast listening.
Professional fluency, register, near-native ease.

FAQ
Just a browser and a microphone. Speaking and the AI voice tutor work best in Chrome or Edge, which support live speech. Everything else works everywhere.
You read a sentence aloud, your browser transcribes it in real time, and Fluido compares it word-by-word to the target, lighting up what you got right and exactly where to fix.
