Build a NotebookLM notebook containing a focused body of material about one subject, using sources such as Google Drive files, websites, YouTube videos, or pasted text. Then request an infographic tailored to a defined audience, publishing channel, and brand treatment. NotebookLM synthesizes the corpus, selects the most relevant ideas, frames them as concise visual messages, and uses Nano Banana Pro to render the asset. Review the result on two dimensions: whether the content accurately represents the sources and whether the visual hierarchy suits the intended channel. Because an initial generation may be only about 80% right, add more explicit visual or editorial direction and regenerate. The output is a fast, source-grounded draft that can make recurring marketing content multimedia without requiring a separate research, writing, and design process.
Origin
Extracted from Marketing Against The Grain, where the host demonstrates creating a LinkedIn infographic from a NotebookLM corpus about Gemini 3.
Core principles
- 01Ground the output in a focused corpus rather than an isolated prompt
- 02Specify the audience, publishing channel, and brand treatment
- 03Judge both visual quality and contextual accuracy
- 04Treat the first generation as a strong draft rather than a finished asset
How to run it
- 1
Define the subject and destination
Choose one focused subject and decide where the infographic will be used, such as LinkedIn, a sales presentation, or an internal update.
Pro tip Name the target audience and channel before collecting sources so the notebook remains purpose-built.
Watch out A broad or mixed subject can produce a visually coherent asset with an unfocused message.
- 2
Build the source corpus
Create a notebook and add relevant source material through file uploads, Google Drive, websites, YouTube videos, or pasted text.
Pro tip Combine complementary sources that cover the subject from different useful angles.
Watch out Do not treat generated wording as reliable if the underlying sources are weak or unrelated.
- 3
Prompt for a contextualized infographic
Ask NotebookLM to create an infographic for the intended channel, audience, and business purpose. Include brand colors or other high-level art direction.
Pro tip Describe the communication job the asset must perform, not merely the desired appearance.
Watch out Leaving the context unspecified encourages generic framing and styling.
- 4
Review content selection and framing
Compare the claims and headings in the infographic with the source corpus. Confirm that the model surfaced the most relevant themes and expressed them accurately.
Pro tip Evaluate contextualization separately from visual appeal.
Watch out A polished image can conceal omissions, weak prioritization, or unsupported claims.
- 5
Direct and regenerate
Identify the missing editorial or visual details, add specific instructions, and regenerate until the result is suitable for use.
Pro tip Convert vague dissatisfaction into concrete changes to hierarchy, density, imagery, or emphasis.
Watch out Do not publish the first generation solely because it was produced quickly.
In the wild
The host assembled a NotebookLM corpus from Marketing Against The Grain and two Gemini 3 videos by Greg Isenberg, including one featuring Logan Kilpatrick. He requested a LinkedIn infographic in HubSpot brand colors without supplying the hexadecimal color values. The result organized marketing use cases such as creating interactive tools, analyzing long videos, improving creative direction, and using generative interfaces for research.
→ NotebookLM produced a contextually relevant visual in about a minute that the host judged roughly 80% complete.
Common mistakes
Judging only the artwork
An attractive infographic is not useful if it selects, frames, or summarizes the source material poorly. Review content accuracy and visual execution independently.
Using an unfocused corpus
Mixing unrelated source material weakens prioritization and makes the generated narrative less coherent.
Publishing the first draft
The first output may be strong but still need more visual direction, tighter wording, or clearer hierarchy.
Is it for you?
Best for
It is best for marketers who have several trustworthy sources and need a visual summary for social media, sales, education, or internal communication.
Not ideal for
It is not ideal when factual precision cannot be checked or when the final design requires exact pixel-level control and manual editing.
From the transcript
“You can upload a source, but you can also link to a G Drive, a website, a YouTube video, paste in any text.”
“I gave Notebook LM the instructions to build an infographic that I could use on LinkedIn. And I asked it to be done in Hubspot…”
“It's maybe 80% of what I wanted to be, not 100%, but this was very good and took a minute.”
