Your AI language tutor that gets you conversational in weeks โ€” not years. Private tutor quality. Available 24/7. No scheduling, no judgment, no awkward silences. Other apps keep you tapping buttons forever. Volley gets you actually speaking from day one โ€” then gets out of the way. โ€” HOW IT WORKS โ€” Three steps. One loop. The method used by polyglots. Listen โ€” AI builds audio lessons around topics YOU care about. Ordering coffee. Work meetings. Travel. Not some textbook from 2003. Speak โ€” Real voice conversations with an AI tutor that adapts to you in real time. It catches your mistakes, remembers what you struggle with, and pushes you just enough. Remember โ€” Your mistakes automatically become flashcards. Spaced repetition makes sure nothing you learn ever fades. Built from YOUR conversations, not a generic word list. โ€” WHY WE'RE DIFFERENT โ€” Other apps: ~12% completion rate. Optimized for addiction. Leaves you unable to hold a real conversation. Volley: 73% reach conversational level. Optimized for fluency. Practice that actually matters. We replace your language app, your private tutor, and your flashcard app โ€” all in one. โ€” WHAT YOU GET โ€” โ€ข Unlimited AI voice conversations that feel like talking to a real person โ€ข Audio lessons generated around topics you actually want to learn โ€ข Smart flashcards powered by spaced repetition โ€” built from your own mistakes โ€ข AI-generated stories read aloud with translations and grammar breakdowns โ€ข Multiple study modes: flashcards, write mode, quizzes, matching games โ€ข Conversation reviews that show exactly where to improve โ€ข Progress tracking across vocabulary, grammar, and speaking confidence โ€ข A coach that knows where you are โ€” and knows where you're going โ€” 6 LANGUAGES โ€” Swedish, Spanish, French, Italian, Russian, Japanese โ€” with more on the way.
