Paste a YouTube link — the live BibiGPT app opens the slide extractor inline. No download, no tab switching.
Paste a public YouTube lecture or conference URL into BibiGPT. The tool watches the full video, groups unchanged frames into unique slides, and exports a PDF or editable PowerPoint plus a timestamped scene transcript. You do not screenshot by hand or download the file first.
AI 检测视频中的幻灯片切换，组装为清晰的 PDF 文档——或可编辑的 PowerPoint（PPTX）——供你复习、标注或分享，不用手动暂停截图。
AI 视觉识别每次幻灯片变化，过滤重复，按顺序导出每页唯一幻灯片。
单个 PDF 文件，逐页排列所有幻灯片，也可导出为可编辑的 PowerPoint（PPTX）演示文稿。可打印、可在 PDF 阅读器中标注，或在 PowerPoint 中复用。
PowerPoint、Google Slides、Keynote、白板——只要画面上出现过，AI 都能捕获。
幻灯片之外，AI 还生成结构化文字稿，将演讲者说的话与每个视觉片段对应——方便搜索和定位。
每个场景包含开始/结束时间的文本段。点击即可跳转到原视频对应时刻。
将完整场景文字稿复制为 Markdown——粘贴到 Notion、Obsidian 或你的研究文档。
画面内容和演讲内容并排展示，非常适合课堂笔记和复习。
AI 挑出视频中最有信息量的帧——图表、代码片段、图形、标注——让你单独下载。
不是每帧都要——只选有意义视觉内容的帧。AI 过滤掉填充画面和转场。
按原始视频分辨率提取帧，不会模糊。
一次性下载所有关键帧为 ZIP 压缩包，离线查看或插入你自己的演示文稿。
The live tool above is the BibiGPT slide extractor. A short lecture usually finishes in a few minutes; you can leave the tab open.
Public lectures, conference talks, and tutorials work. Private videos cannot be analyzed; unlisted videos work if you paste the full share URL.
The extractor detects on-screen slide changes, drops duplicate frames, and maps spoken words to each scene with timestamps.
Export a slide PDF, an editable PowerPoint deck, individual key frames, and a scene-by-scene transcript you can search later.
Where the lecture-capture and export claims on this page come from.
Lecture capture is the practice of recording a class so students can review slides and speech later instead of relying on live notes alone.
Wikipedia — Lecture capture ↗PDF keeps one slide per page in a fixed layout; PPTX keeps the same deck editable in PowerPoint, which is why lecture extractors usually offer both.
ISO 32000 — Portable Document Format ↗A YouTube slide extractor is a tool that watches a lecture or presentation video and saves each unique on-screen slide as a page in a PDF or editable PowerPoint. It detects when the picture changes, filters duplicate frames, and keeps the remaining slides in order. BibiGPT also returns a timestamped scene transcript so each slide is paired with what the speaker said.
A scene-by-scene transcript is a text record that splits a video wherever the picture or topic changes, then writes what was said in that window with start and end times. Unlike a flat caption file, each block maps speech to a visual segment, so you can search a phrase and jump to the matching slide.
Slide extraction needs on-screen content that actually changes. A talking-head video with no slides, diagrams, or board work still produces a scene transcript, but it yields few unique frames because the picture barely changes. Lectures, conference talks, and tutorials with visible decks are the videos this method is built for.
