Video: "Google Gemini Gems + NotebookLM is INSANE!" by Julian Goldie on YouTube.

What Gemini Gems actually are

Gemini Gems are custom AI assistants you configure inside Google's Gemini interface. You define a name, give it instructions, and it retains those instructions permanently — so every conversation you have with that Gem starts with your context already loaded. Think of it as a trained version of Gemini that knows your brand, your audience, your preferred tone, and your typical tasks without you re-briefing it each time.

That's distinct from the standard Gemini chat experience, where every session is blank. A well-set-up Gem for SEO content might know your target keywords, your brand voice, the format you publish in, and your competitors' names — and it applies all of that on the first message.

What NotebookLM does that regular AI tools don't

NotebookLM is Google's research tool — you upload sources (competitor articles, PDFs, transcripts, YouTube scripts, keyword lists) and it builds a knowledge base from them. It can then answer questions about that source material, surface patterns across multiple documents, and identify what's consistently present across top-ranking content for a given topic.

The practical use here is competitive analysis. Upload the top five articles ranking for your target keyword, ask NotebookLM what each one covers, what angle they all share, and what's missing. It's faster and more structured than reading them yourself, and it gives you a content brief that's grounded in what's actually ranking rather than what an AI imagines should rank.

The combined workflow

Julian Goldie's approach joins both tools in a single loop. NotebookLM handles research and analysis — what to cover, what structure works, what the gaps are. The Gemini Gem then takes that brief and drafts the content in the correct format for the intended platform, whether that's a blog post, a YouTube script, or a summary for a Perplexity citation.

One thing worth noting: the same piece of content, adapted slightly for format, can rank as a written article on Google and as a YouTube video simultaneously — targeting the same keyword from two different result types. That doubles the surface area without doubling the research effort, because the NotebookLM work sits underneath both outputs.

The automation layer

With some basic trigger setup, the workflow can run on upload. You drop source material into NotebookLM, a trigger fires, Gemini drafts the content, and it lands in your CMS or YouTube drafts folder ready for review. Julian Goldie cited an example of scaling from one post a week to twenty without additional time investment — which is plausible if the source material is already being collected anyway.

Worth being realistic, though: the quality of the output depends entirely on the quality of the sources you upload. If your NotebookLM knowledge base is thin or outdated, the Gem drafts content from a weak foundation. The automation handles throughput, not judgement. Someone still needs to decide what topics matter and ensure the source material is current.

What's overstated

The alignment argument — that using Google's own AI gives you an inherent ranking advantage — is compelling in theory but unproven in practice. Google has repeatedly said its ranking systems evaluate content quality, not how the content was created. There's no evidence that Gemini-generated content is favoured simply because it came from Gemini. The actual advantage is more straightforward: NotebookLM is a genuinely good research tool, and if your research is better, your content tends to be better.

Where this connects to NordSys

The Gemini and NotebookLM combination is the kind of thing that works well when it's set up properly and breaks down when the source material isn't maintained. We build SEO content workflows for UK businesses — including configuring AI research pipelines and setting up the automation so output lands in the right place without manual steps in between. If you want to put this to work without the setup overhead, our SEO & AI Ranking service is the right starting point.
