- Note that the first thing you're asked to do is sign up to a plan, and the Free one limits you to 20 imports a day.

- so great , I love it
- Jeff Kang
- I reached the limit of NotebookLM notebooks a while ago, and it was tedious having to delete the notebooks one by one. I was surprised that they don’t allow multi-selecting by default. I ended up finding a Reddit thread where the creator left a comment about the extension. It works great for multi-selecting and deleting. Thanks!
- Daniel Gavrilescu
- So far so (very) good. I am using only a decent part of its functionalities and found it very handful , stable and user friendly, like knowing apriori what i need and implemented properly. Keep up the good work !!
- nanomaine
- Love the tool, works great and has lots of features. Had trouble installing, but Gemini had suggestions, and one worked: turn on chrome developer mode: • Open Chrome and type chrome://extensions/ in the address bar. • Enable Developer mode (toggle in the top right). • Attempt the install again from the Web Store. NLM Tools responded quickly to my request for help, but I already had it installed. Great customer service, and fantastic tool!

- Lies 🤥. Does not refresh web articles like it claims, just Google Drive stuff. This article says it will look for stale web links and offer to refresh them. It does not. https://www.nlmtools.com/blog/notebooklm-source-freshness-sync#:~:text=You%20add%20a%20web%20article%2C So much wasted time.

- This is certainly an excellent extension for NotebookLM... I will make sure people know about this useful utility. I am still waiting on the ability to merge multiple sources in a given notebook into one source. Or merging merging multiple webpages into one source before uploading into a Notebook in NotebookLM.
