UMichScribe: Lecture Transcript Exporter

Exports synchronized lecture transcripts and high-res slides from U-M lecture videos for study and AI review. Unofficial.

UMichScribe is a privacy-first, open-source browser extension that extracts synchronized lecture transcripts and high-definition slide milestones from University of Michigan lecture recordings (LecCap, Kaltura, and Canvas LMS). Designed for students who want to study efficiently or feed rich lecture context into modern multimodal AI models (Claude, ChatGPT, Gemini, etc.), UMichScribe pairs spoken instructor dialogue with the exact visual slide frame being discussed. --- 🌟 Key Features 📄 Embedded PDF Export (Best for AI Vision): Embeds full-resolution 960×720 visual slide captures directly on each page alongside synchronized speech cues. Upload directly to Claude or ChatGPT to let multimodal vision read handwritten math, complex diagrams, circuit graphs, and code. 📝 Markdown Export (.md): Generates clean, beautifully formatted notes with `#` headers, slide timestamps, speaker cues, and embedded slide images. Ready for instant import into Obsidian, Notion, Logseq, and Bear. 📄 Plain Text Export (.txt): Pure, lightweight text formatted for universal scratchpads, terminal searching, and fast copy-pasting. ⚡ 10× Fast Parallel Downloading: Employs an asynchronous worker pool with concurrent connections to download 100+ slide frames and compile a complete lecture in just 3 to 4 seconds. 🎯 Smart Lecture Detection: Automatically discovers course numbers and recording dates (e.g., `STATS 250 - 2026-09-02.pdf`) for effortless organization. ⏱️ Time Range Filtering: Filter by custom start and end timestamps to export specific problem walkthroughs or exam review segments. 🧹 Conservative Caption Cleanup: Intelligently merges fragmented captions and removes duplicate cues without altering professor phrasing or meaning. --- 🔒 100% Private & Client-Side Zero Cloud Storage: All extraction, caption merging, and PDF compiling happens entirely inside your browser's memory. No Third-Party Trackers: No analytics, no telemetry, no tracking cookies, and no background beacons. No Video/Audio Downloading: Does not rip or pirate media streams.
