BufferMind is a real-time transcription and translation app built for students learning in a language that is not their first. It listens to your lecture, transcribes every word, and translates it as the professor speaks — so you can follow along live, and actually understand it afterwards. REAL-TIME TRANSCRIPTION Fast, accurate speech-to-text across 15+ input languages including English, Chinese, Spanish, Hindi, Korean, Japanese, French and German, with an auto-detect mode for multilingual classrooms. INSTANT TRANSLATION Original and translation side by side as the lecture unfolds — Chinese, English, Hindi, Korean, Japanese and Spanish. You can also have the translation read aloud through your headphones while class is still running. ANDY, YOUR AI TEACHING ASSISTANT Ask Andy anything about a lecture you recorded and get an answer grounded in your own transcript, not the open internet. Snap a photo of a problem on the board and ask about that instead. Andy also catches the moment your name is called, so you do not miss it. A HISTORY YOU CAN ACTUALLY USE Every session keeps its transcript, translation and audio. Tap any word to jump to that exact second of the recording. Search across everything you have ever recorded. Group sessions into folders by course, and upload the syllabus so Andy knows what the class is about. LIVE ACTIVITY An active recording stays visible on the Lock Screen and in the Dynamic Island, so you can confirm it is still running without unlocking your phone. TALKING TO PEOPLE Push-to-talk translated conversation for talking to someone face to face — Chinese, English, Cantonese, Japanese, Korean, Spanish and Hindi. Add friends to share sessions, chat with text, photos, video and voice messages, or start a voice or video call. TRY IT WITHOUT AN ACCOUNT Tap "Continue as Guest" and start recording, transcribing and translating immediately — no email, no signup. Guest sessions are capped at 10 minutes each. Sign in with Apple, Google, LINE or email to lift that cap, sync across your devices, and unlock Andy, friends and chat. PLANS BufferMind is free to start: creating an account gives you a monthly allowance of recording and AI usage at no charge. When you need more, Pro and Max are available as auto-renewing subscriptions. • Pro — US$9.99 per month, or US$19.99 every 3 months • Max — US$19.99 per month, or US$49.99 every 3 months Payment is charged to your Apple Account at confirmation of purchase. A subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours prior to the end of that period. You can manage your subscription and turn off auto-renew in your Apple Account settings after purchase. PRIVACY Audio streams to our speech-to-text provider (Soniox) only while you are recording, and is not retained on their side once the session ends. Your recordings, transcripts and translations live in your own private BufferMind account. Delete any single session — or your entire account and everything in it — at any time from Settings. We do not track you and we do not sell your data. COMMUNITY GUIDELINES Chat and calls only happen between people who have accepted each other as friends, and you can remove a friend at any time. We have zero tolerance for abusive or objectionable content: press and hold any message to report it, and we review every report.
