Extract Slides & Visuals from Bilibili Lectures
Paste a Bilibili lecture or presentation URL. AI watches the entire video, extracts every slide as a PDF, captures key frames, and generates a scene-by-scene transcript. Pro feature.
Features
Every Slide as a Downloadable PDF
AI detects slide transitions throughout the Bilibili video and assembles a clean PDF deck you can review, annotate, or share — without pausing and screenshotting manually.
Automatic slide detection
AI vision identifies when the presenter changes slides, filters out duplicates, and exports each unique slide in order.
One-click PDF download
Get a single PDF file with all slides laid out page-by-page. Print it, annotate in your PDF reader, or attach to your notes.
Works with any presentation style
PowerPoint, WPS, Keynote, whiteboard — if it appears on screen, AI captures it.
Scene-by-Scene Transcript with Timestamps
Beyond slides, AI generates a structured transcript that maps what the speaker said to each visual segment — so you can search and jump to the exact moment.
Timestamped scene transcript
Each scene gets a text block with start/end times. Click to jump to that moment in the original video.
Markdown export
Copy the full scene transcript as Markdown — paste into Notion, Obsidian, or your research doc.
Speaker + slide context together
See what was on screen alongside what was said. Perfect for lecture notes and exam review.
Key Frame Extraction for Visual Analysis
AI picks out the most informative frames from the video — diagrams, code snippets, charts, annotations — and lets you download them individually.
Smart frame selection
Not every frame — only the ones with meaningful visual content. AI filters out filler and transition screens.
High-resolution captures
Frames are extracted at the original video resolution. No blurry screenshots.
Batch download as ZIP
Download all key frames at once in a ZIP archive for offline review or inclusion in your own presentations.
