Hi everyone!

I've been experimenting a lot with NotebookLM / Gemini Notebook, especially for turning source material into presentations and teaching content.

One thing I kept running into was that the same source doesn't always work well with the same prompt for every audience.

Something made for children usually needs different wording, pacing, information density, and visual direction than something made for young adults or mature readers.

So I started building a small tool around that idea:

Gemini Notebook Prompt Lab

Instead of being just a long list of prompts, it currently has:

• 132 prompts
• 44 visual themes
• 3 audience versions for each theme: Children, Youth, and Mature readers
• A searchable Prompt Library
• A Prompt Lab for building more customized prompts
• Real Gemini Notebook output previews for a growing number of prompts
• Favorites, filters, import/export, and a few other workflow tools

The basic workflow is pretty simple:

choose an audience → choose a style → copy the prompt → use it with your own source in NotebookLM.

The prompts themselves are already complete.

What I'm still working on is the visual example library.

Rather than filling empty cards with mockups or placeholder artwork, I'm only adding examples when I have an actual generated output to show. So some prompts already have real previews, while others are still text-only.

I'll keep adding more over time.

Here’s the live version:

And the project is fully open source here:

https://github.com/dennis23100/gemini-notebook-prompt-lab

I'd really like to hear from people who use NotebookLM regularly:

Would something like this actually fit into your workflow?

And if you have a minute to try it, I'd especially love feedback on:

• missing styles or use cases
• whether the audience-specific versions are useful
• anything confusing in the UI
• features you'd want added next

Still improving it, so criticism is very welcome. Thanks!
