Why in-browser processing is the privacy model this page uses.
WebAssembly lets speech and language models run in a browser tab instead of on a remote server — the mechanism behind on-device transcription.
MDN — WebAssembly ↗Keeping media on-device is the default privacy recommendation when recordings contain other people's voices or unpublished research.
ICO — Audio recording guidance ↗A free video summarizer extracts speech from a file you already have, writes a transcript, then condenses that transcript into key points. BibiGPT runs both steps in the browser on this page, so the MP4, MOV, or WebM never leaves your device. The output is a timestamped transcript plus a short summary you can copy or download.
Yes, when transcription and summary run on-device. A private free video summarizer does not upload the file to a server, which matters for lectures, internal meetings, and interviews you cannot put in the cloud. BibiGPT's file tool on this page is built that way; link-based summaries on other BibiGPT pages fetch a public URL instead.
This free video summarizer is for local files (MP4, MOV, WebM, and similar). A YouTube, TikTok, or Bilibili URL needs a link tool that fetches the page, not an on-device file pipeline. Use BibiGPT's video-summarizer hub for those links; keep this page when the file must stay on your computer.
