# BibiGPT: 4 WebMCP tools for AI agents

![](https://www.google.com/s2/favicons?domain=bibigpt.co&sz=96)

AI & agents · bibigpt.co

## BibiGPT

AI video and podcast summarizer. Agents can summarize videos, summarize by chapter and fetch timestamped transcripts.

[Open bibigpt.co](https://bibigpt.co/en)

## Ask an agent to

-   Summarize this YouTube video in five bullet points
-   Get the full transcript with timestamps of this podcast episode
-   Summarize this Bilibili lecture chapter by chapter in English

## 4 tools

When we loaded bibigpt.co again on Oct 24, 2026, it registered these through `navigator.modelContext` or `provideContext()`, from earlier WebMCP drafts. Chrome 154 only offers `document.modelContext`, so Chrome’s own agent support does not see them.

-   `get_subtitles`
    
    Get the full transcript/subtitles of a video or podcast with timestamps.
    
    url: string
    
-   `summarize_by_chapter`
    
    Summarize a video chapter by chapter. Returns structured summaries per section.
    
    url: string
    
-   `summarize_video`
    
    Summarize an online video or podcast. Supports YouTube, Bilibili, TikTok, Twitter/X, podcasts.
    
    url: string
    
-   `summarize_with_config`
    
    Summarize a video with custom prompt, AI model, or output language.

Tool names and descriptions are what bibigpt.co/en registered when we loaded it in Chrome 154 on Browser Use Cloud. The summary and the “ask an agent” lines are AI-written from them. To call the tools yourself, see [Chrome’s WebMCP docs](https://developer.chrome.com/docs/ai/webmcp). [How we found it](https://browser-use.com/webmcp#method).
