AI video notes generator
AI Video Notes — Summarize Any Video
Turn hours of video into structured notes in minutes. Paste a YouTube link or upload a file — AI extracts key takeaways, creates summaries, and organizes everything into clear, actionable notes.
How it works
Paste a link or upload a video
Copy the URL of any YouTube video or upload a file from your device. No downloads, no browser extensions needed.
AI generates structured notes
AI transcribes the audio, identifies speakers, and distills the content into structured notes with key points, summaries, and highlights.
Ask follow-up questions
Use AI chat to dive deeper. Ask for clarifications, request specific summaries, or extract action items — all grounded in the actual video content.

Behavioral Economics — Nudge Theory and Decision Making
Three key concepts from the lecture:
- Nudge theory — small changes in choice architecture (e.g., defaults) dramatically influence decisions without limiting freedom (Prof. Harris)
- Opt-out vs opt-in framing: organ donation rates jump from 15% to 90%+ just by changing the default option (Prof. Harris)
- Loss aversion — people feel losses ~2x more than gains, driving irrational economic behavior (Prof. Harris)
Today we'll explore nudge theory. The core idea is simple: small changes in how choices are presented can dramatically influence decisions without restricting freedom.
Professor, can you give a real-world example of a nudge that changed behavior at scale?
The classic example is organ donation. Countries with opt-out systems see donation rates above 90%, versus 15% in opt-in countries. Same choice, different default.
Loss aversion is another key concept. People feel losses roughly twice as strongly as equivalent gains. This asymmetry drives much of irrational economic behavior.
