Getting Started: From Video to Permanent Knowledge

Key Features That Make the Magic Happen
1. Screenshots with Timestamps
As the video plays, you can capture screenshots with timestamps. This means you'll never lose track of important visual moments - charts, diagrams, equations, or key slides are preserved forever with context.
2. Multilingual AI Notes
The AI can take notes in any language:
- Watch in English, get notes in Chinese - Perfect for international students
- Korean, Spanish, or any other language - Complete language flexibility
- Multilingual learners - Switch between languages as needed
This feature is perfect for international students or anyone learning in multiple languages.
3. Manual Notes Option
You can also type your own notes without relying on the AI, giving you complete control over your knowledge capture process.
The Magic Moment: AI That Actually Understands
Here's where HoverNotes becomes truly powerful - the AI watches alongside you, seeing charts and equations that appear in the video.
Real-Time Understanding
The AI just wrote exactly what you were trying to write. You can focus on understanding the video and taking screenshots while it handles the tedious typing.
Complex Content Capture
Notice that complex equation? AI Auto Notes captures equations in real-time using both:
- The transcript - What's being said
- The video content on screen - What's being shown
This dual approach means nothing gets missed, even complex mathematical formulas or technical diagrams.
Instant Sync to Your Knowledge System
Your notes are synced and saved into your Obsidian vault as you write them. All screenshots, equations, code, and text appears in your Obsidian note exactly as it appears in your HoverNotes editor.
Connected Knowledge
The video knowledge is now connected to everything else you've learned. You'll never need to rewatch this video to find this information again - it's permanently captured and searchable in your knowledge system.
