Project Fluency™ vs Stack

Every app teaches you a language. None of them prepare you for the country. You did the streak. You passed the quiz. Then you landed and the waiter spoke too fast, used slang the app never taught you, and switched to English because you hesitated. Project Fluency is different. It's an AI + human integrated platform: talk to 60+ AI characters who speak like real people, then bring what you practiced to a real teacher who already knows where you're stuck. The grandmother who won't slow down. The bartender who teaches through stories. The local who won't switch to English for you. Across Spanish, French, Italian, Portuguese, and English. Every other app makes you choose — a cheap app that never talks back, or an expensive tutor you see once a week and forget by Tuesday. That's a false choice. We built both into one thing. CHARACTERS WHO REMEMBER YOU Every character remembers your past conversations. Mess up subjunctive on Tuesday? They'll bring it up on Thursday. Your mistakes become your curriculum. REAL-TIME CORRECTIONS Grammar caught mid-conversation — no pause, no quiz. The character keeps talking. You keep learning. Every session scored with detailed analysis. ADAPTIVE PRACTICE Yesterday's conversation errors become today's drilling exercises. Six practice modes from recognition to full production. Powered by spaced repetition that adapts to your specific weaknesses. REAL TEACHERS, FULLY INTEGRATED Book live sessions with professional teachers — and they walk in already knowing your week. Before every class, your teacher gets a brief built from your actual AI conversations: what you practiced, where you slipped, what to push on. No warming up, no re-explaining your level, no starting over. You practice with AI between sessions. You go deep with a human in them. Nothing falls through the cracks. That's the continuity most apps can't give you. VOICE-FIRST LEARNING This isn't typing into a chat box. You speak. They speak. Regional accents, natural speed, cultural context included. Mexican Spanish sounds different from Argentine Spanish — and our characters know it. 5 LANGUAGES, ONE SUBSCRIPTION Spanish, French, Italian, Portuguese, and English. Characters set in Mexico City, Paris, Rome, Rio de Janeiro, and Chicago. One subscription unlocks everything. WHO IT'S FOR Travelers preparing for real interactions. Professionals who need business language. Heritage speakers reconnecting with their roots. Anyone tired of apps that teach words but not conversation. Start with a free assessment. Get matched with characters built for your level and goals. Practice as much as you want. Bring a teacher in whenever you're ready. Show up — we'll take care of the rest.
