Notion requires endless manual organization. Obsidian needs you to be a power user. NotebookLM can't read half your content. None of them understand how you actually consume information today.
Notion
Great for docs- AI can't read videos or social media
- Manual organization required
- No visual/spatial interface
Obsidian
Powerful but complex- Steep learning curve
- Manual linking between notes
- No AI that understands content
NotebookLM
AI but limited- Can't read TikToks, Reels, or social
- No visual boards
- Limited source types
