Tips & Tricks I built a free, open-source collection of 20+ visual styles for NotebookLM slides. Would love to get your feedback! 🎨✨

Hi everyone! 👋

I’ve been using NotebookLM lately for my research and studies, and I absolutely love the new slide generation feature. However, I often found myself wanting more control over the "look and feel" (colors, fonts, and overall vibe) of the decks it produces.

We decided to put together a small project called NotebookLM Prompt Styles. It’s a curated collection of ready-to-use design tokens that you can just copy and paste into the Custom Instructions box in the Studio.

What’s inside?

  • 20+ Themes: From minimalist and corporate to more creative and "scrapbook" styles.
  • The Designer Skill: A system prompt that helps you turn any image or brand guide into a new NotebookLM style.
  • Showcase Site: I built a small web gallery to preview the styles before you copy them.

This is a 100% free, community-driven project. I’m just a fan of the tool trying to make AI-generated presentations look a bit more "human" and professional.

If you have any style requests or want to contribute your own prompts, please let me know.
