Ever watched a YouTube video and wondered how well you understood its content? Here's a fun twist: Instead of just watching on YouTube, come to **Quizzler** and test your comprehension!
**How does it work?** 🤔
1. Paste the YouTube video URL of your recently watched video.
2. Enter your [OpenAI API Key](https://platform.openai.com/account/api-keys).
⚠️ Important: The video **must** have English captions for the tool to work.
Once you've input the details, voilà! Dive deep into questions crafted just for you, ensuring you've truly grasped the content of the video. Let's put your knowledge to the test!
