Fluo combines spaced repetition with AI-generated sentences tailored to your exact level. Every word you learn stays learned.
No flashcard grinding. No generic lessons. Just science-backed learning that works.
The most effective memory technique ever studied. We show you words right before you'd forget them. Words you struggle with come back sooner. Words you know get spaced out.
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.
Pick your topic — food, travel, business, health, or anything you type in — and practice sentences built around the vocabulary that matters to you.
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. You just practice — the system handles the rest.
See Chinese and recall the meaning. See English and produce the Chinese. Go from recognition to real production — the difference between understanding a menu and ordering from it.
Curious why a word is used a certain way? Wondering about grammar? Tap "Ask" on any sentence and get a clear, detailed explanation — like having a tutor available 24/7.
Simple to start. Powerful as you grow.
Choose a topic or browse vocabulary. Fluo generates sentences using words you're learning alongside words you already know.
Read, listen, and test yourself with AI-generated sentences. Active and passive recall modes push you from recognition to production.
Spaced repetition schedules every review at the perfect time. Track your progress as words move from "new" to "mastered".
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.
Built for learners who want results.
