Build Your Personal Wiki from YouTube Videos

Every video you watch contains knowledge. Most people lose it. You're going to capture it forever.

What's a Personal Wiki?

A searchable database of everything you've learned, organized by topic, with links back to sources.

Traditional wikis require manual writing. Yours builds itself.

The Structure

Level 1: Interests (Auto-Created)

BrainTube automatically detects what you're learning about:

• Machine Learning
• Personal Finance
• Leadership
• Cooking

Each Interest tracks your activity and connects related content.

Level 2: Collections (You Create)

Within each Interest, create specific Collections:

• "ML Fundamentals" (beginner videos)
• "ML Papers Explained" (technical deep-dives)
• "ML Career Advice" (practical guidance)

Level 3: Highlights + Notes (Your Knowledge)

Inside each video:

• Highlights = Important quotes
• Notes = Your interpretation
• Action items = Things to do

How to Build It

Step 1: Create Your Top 5 Collections

Think about your main learning areas:

1. Career/Professional Development
2. Health & Fitness
3. Finance
4. Relationships
5. Hobbies/Skills

Create a Collection for each.

Step 2: Assign Past Videos

Open your Library. For each video:

1. Add it to the relevant Collection
2. Check if you missed highlighting anything important
3. Add one note summarizing why this video matters

Step 3: Use It Daily

When you save a new video:

1. Add to Collection immediately
2. Read the AI summary
3. Highlight + note the key insight
4. Done (60 seconds)

Step 4: Review Monthly

Once a month, open each Collection:

1. Search for connections between videos
2. Use Content Lab to synthesize insights
3. Delete videos that no longer serve you

The Result

After 3 months:

• 50+ videos organized by topic
• 200+ highlights with your notes
• Instant search across everything
• A genuine second brain

Pro Tip

Use the Knowledge Graph to visualize connections between your Collections. You'll discover insights you didn't know you had.
