Most language apps teach you a language. U-say teaches you YOUR language — the words you actually reach for, in the life you actually live. HOW IT WORKS Say what's on your mind, in English. U-say finds the sentences you use most and turns them into Spanish, French, or English you can genuinely say. Not "the pen is on the table." The things you said this morning. SPEAK FROM DAY ONE Talk with an AI partner who is a person, not a quiz. It has a job, opinions, and a bad week sometimes — and it answers what you actually said. It never corrects you mid-sentence, because being interrupted is the fastest way to stop speaking. Afterwards it shows you what a fluent speaker would have said, and why. IMMERSION THAT ARRIVES WHEN YOU'RE READY At the start, your partner speaks English — being spoken to in a language you can't answer in teaches nothing. As you master more, it shifts: greetings in Spanish, then whole conversations, then no translation at all. You never choose a difficulty setting. It simply notices. And if you'd rather be thrown in early, you can set it yourself. A REAL DAILY CLASS Five minutes, one sentence, taught properly: hear it, understand it, spell it from memory, write it, then use it with other learners in your room. Your practice stays private. Only your final answer is shared. LEARN WITH PEOPLE LEARNING WITH YOU Rooms by language and level. Daily prompts everyone answers. Weekly rankings that measure effort, not who started ahead. Every post is safety-checked before it appears. ALSO INCLUDED • Spaced repetition that schedules review before you forget • Screenshot analysis — learn from real messages you receive • Pronunciation coaching with playback comparison • Stories, writing practice, and grammar explained when you need it • A structured Academy path if you want foundations too FREE INCLUDES Daily conversation practice, one personal lesson a day, your full phrase library, review, the Community class, and immersion. U-say+ adds more conversation time, more lessons, deeper insight, and practice built from your mistakes. PRIVATE BY DESIGN Learners under 13 get a completely separate mode: no account, no cloud, no microphone, no data leaves the device. For everyone else, you choose what's stored, you can export it, and you can delete your account in two taps.
