## What is BufferMind?

BufferMind is your real-time AI translation copilot — built for international
  students.

  Class & meetings — turn any lecture, Zoom call, or interview into live
  bilingual captions. Zoned out for a minute? Ask your AI tutor mid-recording:
  "what did the professor just say?" and catch right up.

  Travel & social — hold-to-talk Live Chat. Speak your language, they hear
  theirs in a natural neural voice. Tap any bubble to replay.

  AI that knows your class — upload slides or a syllabus and BufferMind
  learns your course's terminology, so captions and answers always use the right
  terms.

  Everything else:
  • 7 languages — English, Mandarin, Cantonese, Japanese, Korean, Spanish, Hindi
  • Every recording auto-organized — AI titles, summaries, projects, and
  tap-any-line replay synced to the audio
  • Translate any text — paste full documents, translated in one tap
  • Sync across iPhone, iPad, Mac, and Web — with a desktop-class layout on iPad
  • Live Activity on your Lock Screen and Dynamic Island while recording
  • Plays nicely alongside video calls — iPhone's hardware audio isolation keeps
  the other side out of your transcript
  • Neural-quality voice playback for English and Mandarin
  • Free during beta — no ads, no tracking.
  
BufferMind is in active beta — we're a pre-launch project shaping the 
product with early users. Full public launch coming July 2026.

虽然说是我自己做出来的，但是我自己也一直在用，我也想作为一个使用者来写第一条评价。讲真的，Buffermind是我在测试过后发现，它几乎比任何一款翻译软件都更好。我做这个软件的初衷就是，我也是留学生一个，我在课堂上有时候真的有时候会听不懂，有时候会走神，buffermind就是为了解决这一系列问题。不论是课堂，会议，电话，我都可以用得上。摘要和答案我都才用了最好的模型来实现，所以一切都令我自己很满意。
