Why Your YouTube Transcript Isn't Working
YouTube's transcript button is unreliable. It depends on UI state, device, region, and how the creator configured the video — and it breaks in a handful of common ways. The captions almost always still exist; YouTube just isn't showing them. Here's what's going on, and how to get the transcript anyway.
Transcript button is missing entirely
The "Show transcript" option only appears under the "..." menu on desktop, and only if YouTube has surfaced captions for the player. On mobile web and the YouTube app, the button is buried or absent. Embedded players never show it. Paste the URL above and we read the caption track directly, regardless of what the player UI is doing.
"Transcript is not available for this video"
YouTube shows this when the player can't fetch a caption track for your session — but auto-generated captions usually exist server-side. Our tool requests the caption track from YouTube's player API directly, so it works even when the front-end says it doesn't.
Transcript is greyed out
A disabled transcript control typically means you're watching from a restricted region, on a device that doesn't support captions for that video, or in an embed. The captions are still in the manifest — we pull them out.
Brand-new video has no transcript yet
YouTube needs 5–30 minutes to run automatic speech recognition on freshly uploaded videos. If you're hitting a video that just dropped, give it a few minutes and try again — our tool will pick up the ASR track as soon as it's available.
Creator disabled captions
Some creators turn off auto-generated captions in YouTube Studio. In that case there's no caption track at all — no third-party tool can extract one. Your only option is a separate transcription service (e.g. Whisper) that downloads the audio and re-transcribes it.
Livestream replay or YouTube Short
Livestream replays usually get auto-captions once post-processing finishes (can take an hour after the stream ends). YouTube Shorts frequently have no captions at all — that's a platform-side decision, not a bug in any tool.
Private or age-restricted video
Private and unlisted videos require sign-in, so an external tool can't reach them. Age-restricted videos sometimes work, sometimes don't — try pasting the URL above; if it returns "no captions," the restriction is the cause.

常见问题
为什么有的视频没有 YouTube 字幕按钮？
只有当 YouTube 已备好字幕、且创作者没有禁用时，字幕按钮才会出现。它在年龄限制视频、自动字幕仍在处理的新上传视频、直播回放和 Shorts 上经常被隐藏。在上方粘贴视频链接，我们会直接抓取字幕轨 — 无需字幕按钮。
YouTube 提示「此视频无字幕」，怎么办？
YouTube 只有在其界面无法呈现字幕时才会显示该提示，但字幕通常仍存在于服务器端。我们的工具读取原始字幕轨（包括自动生成的 ASR），并以干净的文本显示。只需在上方粘贴链接。
为什么手机上不显示 YouTube 字幕？
YouTube 手机 App 把字幕选项藏在好几层菜单里，iOS Safari 版本则常常根本不显示。我们的工具在任何设备的任何浏览器上都能用 — 粘贴 YouTube 链接，即时拿到完整字幕。
字幕是灰色的 — 还能拿到吗？
字幕变灰通常意味着 YouTube 播放器无法在你当前的视图（手机网页、嵌入播放器或受限地区）渲染字幕。字幕其实仍然存在 — 在上方粘贴链接，我们直接帮你抓取。
为什么刚发布的 YouTube 视频没有字幕？
YouTube 的自动生成字幕在上传后需要 5–30 分钟处理。如果视频刚刚发布，等几分钟再试。字幕轨一准备好，我们的工具就会抓到。
直播或 YouTube Shorts 能拿到字幕吗？
大多数直播回放在处理完成后会有自动字幕。Shorts 往往根本不生成字幕 — 那就没有任何工具可提取的内容。需要登录的私享或不公开视频，外部工具无法抓取。
这个工具免费吗？
是的，完全免费。无需注册、无需账户、没有限制 — 粘贴 YouTube 链接就能复制字幕。
