  专为 YouTube 用户与英语学习者打造的 AI 双语字幕扩展。重点解决传统机翻断句破碎、上下文不连贯的痛点。即装即用，让你顺畅看懂外语内容，在沉浸式观看中同时提升语言能力。
  
  - 为什么你需要雪球？
  
  
许多 YouTube 翻译插件都有一个通病：只是机械地逐行翻译。一旦某句话被硬生生切成两行，翻译出来的中文字幕就会支离破碎、词不达意。
  雪球的解决方案更进一步：先让 AI 理解整句话的真实语境，把破碎的断句重新拼好，然后再进行翻译。这样生成的双语字幕不仅连贯，而且符合正常的阅读逻辑。无论是看科技评测、TED 演讲还是编程教程，都不会再因为糟糕的机翻而出戏。
  
  - 核心体验亮点
  
  ● AI 智能断句与翻译：跳出字对字翻译的局限。引擎会根据上下文重组句子，生成的字幕通顺自然。6秒内极速加载，告别漫长的缓冲等待。
  ● 视频全文转录：真正的生肉救星。即使原视频没有提供任何自带字幕，AI转录功能也能直接通过听音，快速生成精准的双语字幕以及内容总结。
  ● 精准定位视频内容：侧边栏可实时生成完整的双语字幕剧本，点击任意一句话，就能精准空降到对应时间点，找关键信息更方便。
  ● 逐词高亮跟随：独有的逐词高亮同步，让视线随着声音一起走。再也不用在画面和字幕之间来回找焦点，练听力更加舒适。
  ● 高自由度字幕样式：看腻了黑底白字，或者字幕总挡住画面？你可以按喜好调整字体、颜色、背景甚至描边效果，在清晰美观的同时不破坏视频的观看体验。
  ● 高精度的语音识别： 无惧口音与生僻词。只要视频原声相对清晰，AI 就能有效应对各种复杂的英语口音和专业术语，准确率极高。
  ● 内置英语学习助手：看视频遇到生词？直接在字幕上划词翻译，提供准确释义的同时，接入了听感自然的微软 AI 语音引擎，方便随时跟读。
  ● 基本功能免费：每天都会重置一定时长的免费翻译额度，足够满足大多数用户的日常观看需求。

  SubKun — AI YouTube Transcript, Summary, Subtitles & Ask AI
  
  SubKun turns any YouTube video into readable subtitles, a searchable transcript, a clear summary, and an AI you can chat with. Get the gist in seconds, find the exact moment that matters, and ask questions about anything you just watched—all without leaving the page.
  
  Why SubKun?
  
  Most YouTube tools stop at line-by-line translation. When a sentence gets split across two caption lines, the output falls apart—broken phrases, missing context, no real meaning.
  SubKun goes further. Our AI reads the full context of each sentence, stitches fragmented segments back together, and produces subtitles, transcripts, and translations that actually make sense. The result reads the way humans write—perfect for skimming long videos, pulling quotes, or summarizing tech reviews, TED Talks, podcasts, and tutorials in seconds.
  
  Key Features
  
  ● Full Video Transcript in Seconds — Get a complete, timestamped transcript of any YouTube video—even when no captions exist. Our AI listens to the audio directly and generates accurate bilingual transcripts in under 6 seconds. No more pausing, rewinding, or guessing.
  ● Instant AI Summary — Don't have 40 minutes? Get the key points in 40 seconds. SubKun condenses long videos into clean, structured summaries so you can decide what's worth watching—or skip straight to the takeaways.
  ● Ask AI About Any Video — Chat with the video like it's a document. Ask "What did the speaker say about X?" or "Give me the three main arguments" and get instant, context-aware answers grounded in the actual content.
  ● Click-to-Jump Navigation — The sidebar shows the full bilingual transcript in real time. Click any line to jump straight to that moment in the video—perfect for research, reviews, and pulling reference clips.
  ● AI-Powered Bilingual Subtitles — Beyond word-for-word translation. Our engine reconstructs sentences based on full context for subtitles that read naturally, not robotically.
  ● Smart English Subtitles — Re-Punctuated for Reading — YouTube's auto-captions break sentences mid-thought and skip punctuation entirely. SubKun's AI re-segments captions into clean, complete sentences with accurate punctuation, so the English script reads like real writing—perfect for note-taking, study, and pulling quotes.
  ● Word-by-Word Highlight Sync — Subtitles light up word by word, in time with the speaker—so it's easy to follow along with dense or fast-paced content, even at higher playback speeds.
  ● Fully Customizable Subtitle Styling — Adjust fonts, colors, backgrounds, and stroke effects so subtitles look clean and stay out of the way.
  ● High-Accuracy Speech Recognition — Handles diverse English accents and technical jargon with exceptional accuracy, as long as the source audio is reasonably clear.
  ● Inline Word Lookup — Hover or click any word in the transcript for an instant translation, complete with natural-sounding pronunciation powered by Microsoft's AI voice engine.
  ● Free Daily Quota — Generous free credits reset every day—plenty for everyday viewing, research, and summarizing.
