Lohnenswerte Erweiterung für Gemini Notebook
Ich bin mit Kortex sehr zufrieden, bietet für mich genau die Weiterungen in Gemini Notebook, die mir gefehlt hat.
Dadurch wird meine Arbeitsweise effizienter und erheblich erleichtert!

Finally, the missing knowledge management layer for NotebookLM
I love NotebookLM, but what always frustrated me was the lack of organization—no folders, no real structure, and no easy way to manage multiple notebooks. Kortex solves that problem and takes the NotebookLM experience to a whole new level.
The second reason I bought it was knowledge management. I use Claude, ChatGPT, and Gemini every day, and over time I've built a huge library of valuable AI conversations. Finding and organizing them later was always a challenge. Now I export my most valuable chats to NotebookLM, and with Kortex I can organize them by topic and quickly find the information I need.
For me, Kortex doesn't replace NotebookLM—it unlocks its full potential by making knowledge truly organized.
Highly recommended for anyone who uses NotebookLM as a serious knowledge management tool.

IT DOES NOT WORK
It completely fails to fetch any of the notebooks or create a new notebook. It's unable to add anything to an existing notebook or to a new notebook. The core functionality of this app does not work at all.

Jul 29, 2026Hey Ryanz ,
As I mentioned in founders post, it is temporary and the fix is published. It is in the review process from google, and will be available in few days. Thank you for your patience.
