Introduction
As the number of presentations I need to produce grew, the time I could spend perfecting each one shrank. I finally abandoned PowerPoint, Canva, and similar tools in favor of Google NotebookLM’s Slide Decks.
What Is Slide Decks?
Slide Decks, launched in November 2025, converts the sources you upload to a NotebookLM notebook into a full‑fledged presentation. You can choose between two formats:
- Detailed Deck – information‑rich slides that cover every key point.
- Presenter Slides – concise, audience‑focused slides that balance clarity and brevity.
The feature is powered by Google’s Nano Banana image model and was released alongside Infographics.
How It Works
Unlike generic AI slide generators, Slide Decks pulls *only* from the documents you upload. No internet‑wide training data, no random assumptions. The output is entirely driven by the prompt you provide.
Crafting Effective Prompts
The quality of the deck hinges on prompt detail. I usually include:
- Presentation length and audience.
- Slide‑by‑slide outline request.
- Visual description for each slide (images, diagrams, QR‑code placeholders).
- On‑screen text limits (3‑5 bullet points).
- Design style (dark mode, minimalist, professional, etc.).
Example template:
- "I have a [X‑minute] presentation for [audience] titled '[Title]'. Generate a slide‑by‑slide outline with visual description, bullet points, and design style."
Pros and Cons
- Pros
- Turns days of work into an hour.
- Ensures content stays true to uploaded sources.
- Highly customizable via prompt engineering.
- Cons
- Cannot edit slides directly inside NotebookLM (as of now).
- Requires very detailed prompts for optimal results.
Workarounds and Future Outlook
When minor tweaks are needed, I download the generated PDF and edit it in a secondary tool. Google has hinted at upcoming edit capabilities, which would make the feature “truly unstoppable.”
