Just starting to use Kortex, great product. It appears to be a great addition to NotebookLM. Together they make an outstanding product.
Thomas Jaeger (Tom)
Amazing tool! Very helpful and an absolute time saver! My recommendation!
Mark Trexler
Amazing product, and the developer is so responsive! Well worth the purchase price.
Jenni Duncombe
Love! love! love! - and I'm only using the free version. Huge time saver - no NotebookLM user should be without it! I'm definitely considering the Pro version once I get my business beyond the early start up stage.
Alejandro Peterson
So far so good
Paul Lavis
I would echo that it's definitely worth the buy. I have made some requests of the team over the last few days (around podcasts, Spotify and other bits) and they have been fantastic at sorting the issues I raised and made the tool better as a result. Excellent tool, it's getting better and they are very responsive!
Dave Gould
Def worth the buy. I have been using NBLM since the first release. I have lots of notebooks and this tool helps me keep them same, particularly the ability to Merge. There is still a few glitches in the ui. Still a 5 star rating, but would hope they continue developing and updating.
Roberto Ruiz
This is a very handy and useful tool.
J.G.A. Talboom
Perfect
Bobby Hayes
So the app really shines in features that notebook LM should have that they don't. So it does fill a gap. So it's definitely needed. Only gripe it is kind of buggy on some things. I don't know if it's just me, but I do have issues with the podcast feature working correctly sometimes it doesn’t push to my podcast app and download right away. Also, it gets stuck, then skips to the next podcast.
Gregg Maynard
This has been a real game changer for me. As a very early adopter of NotebookLM, this puts it in a whole other gear. It gives me, in my AI consulting service business, a real step ahead of the competition. The features in the pro version are out of this world. Definitely worth looking into a subscription. And can I tell you about the support? I had a small issue with licensing and heard back from their support group within minutes, some of the best customer service I've ever encountered.
Krishna
Amazing tool! Just blew my mind looking at the use cases that it can handle. Addresses almost all the pain-point a notebooklm power user struggles with. Kudos to the team!
Chris Marsh
What a great tool! This makes a great tool even better!! Great work!!
Andre Van der Westhuizen
NB-LM will not be useful to me without it!
Luigino Bottega
Great tool!
Phung Quyen
Great, useful tools, doing a lot of things that NotebookLM is supposed to do in the first place. I can also see some new helpful features being updated regularly. Again, great stuff. 5/5 no doubt about it.
Greg Kanczes
A great tool, opened up all of Notebook LM's functionality for my ChatGPT and Gemini chats!
Lars Algermissen

Super! Simply Amazing
hans blink
I'm using this and it's saved me a lot of extra work for my one-man pensioner club. Highly recommended!
Stefan Živojinović
Very useful !
Jet Mojica
Very useful.Kortex-NotebookLM has started to earn a regular spot in my workflow. What really sold me is how easy it is to import conversations from different LLMs. I can take chats from ChatGPT, Claude, Gemini, and others and bring them straight into NotebookLM without the usual copy-paste cleanup. It is not perfect yet. I sometimes wish the organization and metadata controls were a bit more flexible. Still, it does something genuinely useful by bridging live AI conversations and long-term research notes. Solid 4 stars, and I am starting to enjoy using it more and more.
Leslie
Fantastic... and fast, helpful support!
Acey Tech
Simply Amazing. So many features that -IMHO- NotebookLM should have included in the first place. Thanks to the Devs!
Jihaad Haulkhory
Very helpful tool. It completes Notebook LM and improves efficiency.
Samuel Figueroa
I have installed the extension but have yet to use it much. I'm impressed with what I have tried so far. Excellent features greatly improving NLM. I had a question and contacted support. The help provided was one of the best received recently. That alone was enough to buy the lifetime subscription
Ashutosh Wakankar
Incredibly helpful, timely and intuitive. Hope it remains that way.
JGL
Extremely helpful. Provides exactly the functions which I had preposed already to Google!
bryan ramadhan
very good ...
Imran Virji
So far so good. Pulling sources from reddit is very cool.
Moses NTAM (Dr. NTAM)
Very great tool, time saver for repeated task, my favorite for the moment is the prompt saver. Have not yet explored most of the other features
Suresh Srinivas Ramesh
Great features, saves a lot of time by adding extra features that should have been added by google.
Frederik Schrader
Bought the lifetime license after about 30 seconds. Which probably says a bit more about Google than about this extension's dev, but it IS very well made and I haven't encountered any bugs yet. Thanks for doing what Google for some reason refuses to do -- can you please do the Gemini Web app next? :D
Tarek Salem.
So far it's good and the lifetime price is fair.
Jason Neiffer
This adds much needed features to NotebookLM. I upgraded... which was totally worth it!
