## How do marketers use Kortex?

Marketers use Kortex, a Chrome extension for Gemini Notebook (formerly NotebookLM), to collect customer language from Reddit, X and LinkedIn, competitor pages and their own brand docs in a notebook per campaign or audience. They ask it for angles and objections with citations, keep brand prompts one shortcut away in any AI chat, and export briefs as Markdown or PDF.

## Where marketing research gets lost

The best copy uses the customer’s own words. Kortex helps you keep them.

-   **The perfect customer quote was in a Reddit thread you scrolled past.**
    
    Send Reddit posts with their top comments, X threads and LinkedIn posts with the author to the audience’s notebook in one click.
    
-   **Competitor positioning is a dozen sites you check by hand.**
    
    Crawl each competitor’s site into a notebook and ask how they position against you.
    
-   **AI copy drifts away from your brand voice.**
    
    Keep your brand guide in the notebook and your brand-voice prompts in the Prompts library, one `;shortcut` away in ChatGPT, Claude or Gemini.
    
-   **Briefs don’t say where the insight came from.**
    
    Gemini Notebook answers from your sources and cites each point, so the brief can point at the thread or page behind it.
    
-   **Every campaign starts a new folder of tabs.**
    
    Duplicate last campaign’s notebook in one click, or save it as a template with its tags and collection.
    

## From customer words to the brief

From what customers say to what goes in the brief.

### Collect the customer’s own words

Objections and phrases from real threads, each with its source.

1.  Create a notebook per audience, like Ops leads, in an Audiences collection.
2.  Send Reddit threads with their top comments, X threads and LinkedIn posts where they describe the problem.
3.  Add review exports and survey responses as sources too.
4.  Ask for the objections and phrases that come up most, each cited to its source.

### Map competitor positioning

How each competitor positions and prices, from their own pages.

1.  In Bulk Import, crawl each competitor’s site to the depth you choose, or paste their landing page links.
2.  Add a Domain Router rule so new links from those domains go to the Competitors notebook.
3.  Ask how each one positions, prices and answers your strongest objection.
4.  Save the answer as a note and export it as PDF for the team.

### Keep AI copy on brand

Your voice prompts, one shortcut away in any AI chat.

1.  Send your brand voice guide from Google Docs to a Brand notebook.
2.  Save your brand-voice, headline and ad-variation prompts in the Prompts library, each with a `;shortcut`.
3.  In ChatGPT, Claude or Gemini, type the shortcut and the prompt drops in. Send the finished chat back to the campaign’s notebook.
4.  Keep the prompts you reuse in your Prompts library.

### Turn the research into a brief

A brief whose insights point at their sources.

1.  Tick the audience and competitor sources and ask for a campaign brief: audience, problem, proof and objections.
2.  Generate a briefing doc or an infographic from the same sources.
3.  Export the brief as Markdown for your docs, or PDF for the team.
4.  Planning content from it? The [research to content planner](/tools/research-to-content) has the prompts.

## What reviewers say about these features

Quoted word for word and linked to where they were posted. Reviewers don’t say what they do for a living, so we picked reviews about the features on this page.

> “Kortex turns NotebookLM into an actual knowledge base instead of a fancy note dump. Highlighting text from any webpage and sending it straight in feels borderline magical.”

## What marketers ask

Something we missed? [Ask us](#contact).

### Can Kortex save Instagram or TikTok posts?

Not with the send button, which covers X, Reddit and LinkedIn. On other sites, highlight the text you want and right-click to send it.

### Will it write the copy for me?

Gemini Notebook drafts from your sources, and your saved prompts work in ChatGPT, Claude and Gemini too. Kortex keeps the research and the prompts in order; the copy still needs your edit.

### Can it keep tabs on competitors?

Crawl their sites into a notebook and run the crawl again when you want a fresh copy. Kortex MCP can also ask a notebook a question on a schedule.

### Does it work with HubSpot or Google Analytics?

There’s no direct integration. Export the reports as documents and add them in Gemini Notebook.

## Start with the audience you know least.

Add Kortex to Chrome and send the next Reddit thread where a customer explains their problem.
