Last year, I came across NotebookLM and immediately noticed a pain point: importing the web pages I was browsing into NotebookLM required several steps. So in less than a day, I developed this Chrome extension: NotebookLM Web Importer[1], which allows for one-click importing.
As NotebookLM has gained popularity this year, my extension has also seen great growth. So, in July, I added paid premium features to unlock additional features. It exceeded my expectations and quickly went over $500 a month. It now has over 100,000 users and is still growing.
