One notebook per company you cover.

Kortex keeps each company’s filings, call transcripts, notes and AI research in its own Gemini Notebook, so every answer cites a document you can check.

How do financial analysts use Kortex?

Financial analysts, investors and advisors use Kortex, a Chrome extension for Gemini Notebook (formerly NotebookLM), to keep one notebook per company or theme with its filings, earnings call transcripts and saved AI research, and to ask questions answered with citations. They follow their firm’s client-data and record-keeping policies, and export notes and briefs as PDF or Markdown.

Client data and advice

Kortex sends what you import to Gemini Notebook in your own Google account; Kortex itself doesn’t keep your chats or the contents of your sources. Follow your firm’s client-data, confidentiality and record-keeping policies before adding anything about clients. Kortex doesn’t give investment advice, and we don’t claim it meets any financial regulation.

Where the research trail breaks

Numbers need sources. Kortex keeps the documents behind every view in one place.

From filings to the brief

For your own research. Client material follows your firm’s policies.

Set up a notebook per company

Each company’s documents in one notebook, labelled by type.

  1. Create a notebook for each company you cover and file them in a Coverage collection.
  2. Paste the filing and investor-relations links into Bulk Import, or let the web crawler follow the IR site to the depth you choose.
  3. Add PDFs of the annual report in Gemini Notebook as usual.
  4. Tag sources by type, like Filing, Transcript or Note, and filter by them.

Work through an earnings call

Guidance changes and management’s answers, each tied to the transcript.

  1. Add the call transcript to the company’s notebook.
  2. Insert your saved earnings-call prompt: guidance changes, margin drivers and management’s answers to the hard questions, each with the passage cited.
  3. Ask how this quarter’s guidance compares with the last filing in the notebook.
  4. Save the answer as a note and export it as PDF or Markdown.

Check AI research against sources

Every AI claim sits next to the documents that can confirm or contradict it.

  1. Run your theme research in Perplexity, ChatGPT or Claude.
  2. Send the chat to the theme’s notebook. Your prompts and the replies are labelled, and Perplexity threads keep their citations.
  3. Ask Gemini Notebook where the AI research and the filings disagree.
  4. When the chat continues, send it again and the source updates instead of duplicating.

Get a weekly brief on your watchlist

A note on what changed, waiting on Monday morning.

  1. Connect Kortex MCP to Claude or ChatGPT.
  2. Say once: “Every Monday at 7, ask my Watchlist notebooks what changed and save the answer as a note in my Weekly notebook.”
  3. It runs on your computer’s clock while Chrome is running. See how schedules work.

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.

“Brilliant! Is going to save me hours. I can make all sorts of enquiries in Gemini and then Kortex consolidates them into a single notebook where I can review what I have found and make sense of it all. Thank you.”

Questions people ask

Something we missed? Ask us.

Can I add client information to a notebook?

Only if your firm’s policies allow it. Kortex sends what you import to Gemini Notebook in your own Google account and doesn’t keep your chats or the contents of your sources, so your firm’s client-data and record-keeping rules decide what goes in. See is Gemini Notebook safe and private?

Can Kortex pull live market data?

No. Kortex brings in the documents and pages you choose, like filings, transcripts and articles. It has no market data feed, and Gemini Notebook answers only from what’s in the notebook.

Does Gemini Notebook get the numbers right?

It quotes from your sources and cites them, but it can misread a table. Open the cited passage before a figure goes into a model or a client document.

Can I crawl an investor relations site?

Yes. Start from the IR page, choose how many links deep to go, and each page becomes a source. Gemini Notebook’s cap on sources per notebook still applies.

Is this investment advice?

No. Kortex organizes the research you choose to add, and doesn’t give investment advice.
