Fluo - Learn Chinese

The fastest way to build a Chinese vocabulary that actually lasts! Fluo combines spaced repetition — the most effective memory technique ever studied — with AI-generated sentences tailored to your exact level. No flashcard grinding. No generic lessons. Every word you learn stays learned, because every review is timed perfectly and every sentence is built just for you.

Adaptive learning
Every sentence adapts to where you are right now. Words you know appear alongside words you're learning, so you're always challenged but never overwhelmed. As you improve, your sentences evolve with you — and you can listen to native audio for every single one.

Learn what you actually care about
Pick your topic — food, travel, business, health, or anything you type in — and practice sentences built around the vocabulary that matters to you. No more memorizing words you'll never use.

Every word tracked, nothing left to chance
Tap any word to see how well you remember it. Fluo tracks your recall for every single word and schedules reviews at the optimal time. Words you struggle with come back sooner. Words you know well get spaced out. You just practice — the system handles the rest.

Test yourself in both directions
See Chinese and recall the meaning. See English and produce the Chinese. Fluo's active and passive recall modes push you from recognition to real production — the difference between understanding a menu and ordering from it.

A tutor on every sentence
Curious why a word is used a certain way? Wondering about grammar? Tap "Ask" on any sentence and get a clear, detailed explanation. It's like having a Chinese tutor available 24/7.

Translate anything, learn from everything
Paste any Chinese or English text into the translator and instantly see a word-by-word breakdown — color-coded by how well you know each word. Turn real-world Chinese into a learning opportunity.

Stay on track
Set daily goals, build a streak, and watch your vocabulary grow. Fluo keeps you consistent with clear progress tracking so you always know exactly where you stand.
