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.
