Kortex turns Google's minimalist notebooks into an enterprise command center.

Pros:
Organization: Adds hierarchical folders, nested subfolders, tag management, and global search.
Automations: Conditional workflows (e.g., auto-generate audio or briefing docs when tags update).
Cross-Platform Ingestion: Bulk imports from ChatGPT, Claude, Perplexity, and RSS.
Podcast Engine: Converts audio overviews into true RSS feeds for Spotify/Apple Podcasts.

Cons & Risks:
Wrapper Vulnerability: Reliant on Google's UI/API updates.
Complexity: Over 80 features risk overwhelming casual users.
Privacy: Routing multi-platform data through a third-party extension.

Verdict: Essential for power users and heavy researchers boxed in by native limits; overkill for casual workflows.
