Kortex-Notebooklm

The honest comparison nobody else will write

NotebookLM is exceptional at one thing: synthesizing sources into grounded, citation-backed answers. Google built something genuinely different here. We're not going to pretend otherwise.

But NotebookLM was designed as a research assistant — not a knowledge operating system. The moment you need to do something with your research, the gaps become obvious.

What default NotebookLM gives you

| Feature | Default NotebookLM |

| AI answers from your sources | ✅ Excellent |

| Audio Overview (podcast) | ✅ Built-in |

| Source upload (PDF, doc, YouTube) | ✅ Works well |

| Export your sources | ❌ Not possible |

| Export chat history | ❌ Not possible |

| Notebook organization | ❌ Flat list only |

| Search across notebooks | ❌ Doesn't exist |

| Automation | ❌ Manual only |

What Kortex adds on top

Kortex doesn't replace NotebookLM — it installs as a browser extension and adds features directly inside the NotebookLM interface.

Export: unlock your data

This is the #1 request from NotebookLM users. Kortex lets you export:

• Sources — individual files or entire notebooks as PDF, Markdown, or ZIP

• Chat conversations — full dialogue with citations

• Artifacts — Briefing Docs, Study Guides, FAQs

Organization: escape the flat list

With 20+ notebooks, default NotebookLM becomes unmanageable. Kortex adds:

• Collections — group notebooks into folders

• Color-coded tags — #research, #client, #urgent

• Smart Search — real-time search across all notebook titles and tags

Automation: set it and forget it

This is where Kortex separates itself. Instead of manual steps, you define rules:

• When a new notebook is created → run Auto-Researcher to generate a Briefing Doc

• When a notebook is tagged #podcast → add its Audio Overview to my RSS feed

• When tag #urgent is added → also add #priority

Who should use Kortex

Add Kortex if you:

• Have more than 10 active notebooks

• Need to export research for reports, teams, or other tools

• Want to automate repetitive research workflows

• Use Audio Overviews and want a personal podcast feed

Stick with default NotebookLM if you're an occasional user with a small number of notebooks and no need to move data out.

Bottom line

NotebookLM is the engine. Kortex is the cockpit. They're better together.
