This is incredibly good. It lets me choose from many designs, and it applies them faithfully in NotebookLM. It is a very strong tool.Translated from Japanese.
The prompt collection is fun just to browse, and it is great that I can make and try many things.
Saving favorites is extremely convenient. The one-click workflow is easy, and for someone like me who is not good at design, this is the perfect tool.Translated from Japanese.

FAQ
Only the common points of confusion
Question
Did NotebookLM become paid after the update?
Answer
NotebookLM integration remains free. Paid access only applies to AI Chat integration for ChatGPT, Grok, and Gemini. If you only use NotebookLM to read materials and call design prompts, you are still in the free scope.
Question
What do I get after purchase?
Answer
After purchase, you can insert saved styles, Popular, Business, and Daily Prompt directly into the selected AI Chat, or into ChatGPT, Grok, and Gemini with Bundle.
Question
Do I need to buy anything if I only use NotebookLM?
Answer
No. If you only use NotebookLM, you do not need to choose a plan. The NotebookLM button and catalog remain free.
Question
Can I hide the input button?
Answer
Yes. Open the Chrome extension icon → BananaNL → Options to adjust where NotebookLM and AI Chat buttons appear. If you only want the free NotebookLM flow, turn AI Chat access off and hide the ChatGPT, Grok, and Gemini buttons.
Question
I purchased, but the button does not appear
Answer
First reload the ChatGPT, Grok, or Gemini tab. If it still does not appear, check that AI Chat access is enabled in Options, then refresh purchase status or re-authenticate.
