YouTube Bilibili AI Summarizer(影片字幕摘要器是什麼

Chrome 商店介紹

Summarize captions from YouTube, Bilibili, and other video sites with your own AI API. Video Caption AI Summarizer turns accessible video captions and transcripts into clear, reusable AI summaries. It is built for people who learn, research, review, and work from long-form video on common video and course pages.

Instead of rewatching a long lecture, interview, product demo, technical talk, or course video just to find the key points, you can read the available captions, send them to the AI service you configure, and copy structured Markdown notes from the video page.

Main features:

Summarize captions from supported video pages and generic HTML5 video pages.
Read available caption tracks, VTT/SRT subtitles, visible transcript text, or manually pasted transcript content.
Bring your own AI API or local model endpoint instead of being locked into one provider.
Save multiple API profiles with provider type, endpoint, API key, model name, temperature, and output token limits.
Start quickly with preset configuration templates in Settings, then edit the endpoint and model details for your own account.
Customize summary prompts, output templates, summary language, tone, structure, and detail level.
Split long transcripts into chunks, summarize each part, then merge the final result.
Copy generated Markdown summaries or original transcript text for notes, research, documentation, and knowledge-base workflows.
Control privacy details such as timestamp sharing, sensitive term redaction, and optional local summary history.
Use light, dark, or automatic theme settings for the floating video-page panel.

Good for:

Students and self-learners summarizing lectures, tutorials, course videos, and conference talks.
Researchers and analysts reviewing interviews, presentations, webinars, and recorded discussions.
Creators and product teams turning video material into outlines, notes, briefs, or reusable references.
Developers and AI users who prefer using their own API key, local service, or compatible endpoint.

Privacy and data handling:

The extension sends the selected caption or transcript text to the AI service configured by the user. API keys and settings are stored in local browser extension storage. If local history is enabled, recent summaries are stored locally in the browser. Users can disable timestamp sharing and configure sensitive terms to redact before sending text to their chosen AI service.

Important limitations:

The extension can only summarize captions or transcript text that the browser can access. It may not read captions that are burned into the video image, protected by DRM, hidden behind unavailable account permissions, or changed by a platform update. When automatic caption detection is unavailable, users can paste transcript text manually.
