5 Steps To Build An AI Board Of Advisors In Gemini Notebook, So You Can Pressure-Test Any Decision, Opportunity, or Idea

Hey there!

You make most of your hardest calls of the year with nobody in the room who has done it before.

There is a budget gap you need a plan for by Thursday, a staff hire you are two thirds sure about, and 340 survey responses sitting in a spreadsheet that could support three different conclusions. You can call three people you trust. Two take a week to get back to you, and the third answers through the lens of whatever happened at their last church. The decision still has a date on it.

So today I'm going to show you how to build a standing board of advisors inside Gemini Notebook that you can convene in about ninety seconds, on any decision, with advisors who disagree with each other in front of you and then hand you a sequenced plan.

Let's build it.

(Quick naming note: Google renamed NotebookLM to Gemini Notebook in July 2026. Same tool, same login, and your old notebook links still work.)

Start with three to five advisors and go deep on each one.

The instinct is to load 20 voices. Resist it.

Four advisors with ten or fifteen pages of real thinking each will out-advise twenty with a paragraph apiece. Gemini Notebook answers only from what you give it, so a thin advisor gives thin counsel and says so.

Pick your four by the seat they hold in the room:

1. The operator who has run a staff and a budget through a hard season
2. The money mind who thinks in generosity, development, and cash flow
3. The governance voice who thinks in bylaws, fiduciary duty, and risk
4. The skeptic whose entire job is naming what will go wrong

The free tier holds 50 sources per notebook, which is plenty. Four advisors with a handful of documents each leaves you room to drop in your own data later.

Give every advisor their own labeled source file.

This step decides whether you get four voices or one blended mush.

Create one document per advisor and name it so there is no ambiguity about who is speaking, like ADVISOR | Governance | ECFA Standards and Board Practice. Inside, capture how that advisor thinks. Their frameworks, the beliefs they will not trade away, a few direct quotes so the voice carries, and two or three real examples of them applying it. Upload each one as its own separate source.

Separate sources give you a second power. Every source has a checkbox in the left panel. Uncheck three of them and you are talking to one advisor alone.

Free public sources you can load without a copyright headache:

1. Podcast transcripts and show notes from leadership shows you already trust
2. Conference talks and public YouTube sessions
3. ECFA's free governance library, bylaws templates, and the Church & Nonprofit Tax & Financial Guide
4. Lake Institute on Faith & Giving research and the free Giving USA key findings
5. Bridgespan's free strategy and funding-model articles, and Pew's Religious Landscape data
6. Books and PDF's you have purchased that are relevant

Keep identifiable congregant and donor records out of it. Aggregate the survey, strip the names, then upload.

Set your custom instructions once so the board behaves like a board.

Open the chat panel and click the slider icon at the top. Choose Conversation style, then Custom. You get 10,000 characters, and whatever you write there governs every conversation in that notebook from then on.

Paste this in and edit the names:

You are the facilitator of my advisory board. Each source
document labeled ADVISOR is one board member.

When I ask a question:
1. Have each relevant advisor respond in turn, in their own
voice, beginning with their name in brackets, grounded ONLY
in their own source documents.
2. Never blend two advisors into one voice.
3. Cite the specific source behind every claim.
4. After all advisors speak, add a section titled "Where the
board disagrees" naming the real tensions between them.
5. Close with "Facilitator's synthesis": a prioritized,
sequenced action list with owners and timeframes.
6. If a topic is absent from an advisor's sources, have that
advisor say so plainly instead of guessing.

Audience: the senior leader of a church or faith-based
nonprofit. Speak plainly. No jargon.

Set it once. It runs on every question you ask after that.

Ask your first question with a diagnose, argue, decide structure.

Here is the base prompt for your first board meeting. Swap the situation and keep the rest as your template.

SITUATION: [Describe the decision in 4-6 sentences. Include
the numbers, the timeline, who is affected, and what you have
already tried.]

STEP 1, DIAGNOSIS: Each advisor states what they believe is
actually going on here, from their own lens, in under 150
words.

STEP 2, PRESCRIPTION: Each advisor gives their specific
recommended action and the single assumption it rests on.

STEP 3, CROSS-EXAMINATION: Each advisor articulates the strongest objection to the other advisors' prescriptions. Be direct.

STEP 4, CONVERGENCE: Produce one prioritized, sequenced
90-day action list. For each action give the owner, the week
it starts, and the one metric that tells us it worked.

STEP 5, OPEN QUESTIONS: List what the board still disagrees
on and what evidence would settle it.

Step 3 is the part I love. It makes each advisor defend a position against the others, and that argument is what you would otherwise pay three consultants to stage for you. Leave it out and the board is just a polite messy list of things.

Point the same board at six different kinds of decisions.

One notebook covers you all year. The prompt above stays put and only the situation changes.

1. Survey and feedback data. Paste your congregational or donor survey results in as a source and ask the board to diagnose the themes before you form your own read.
2. A facilities or building call. The governance advisor weighs debt and fiduciary duty while the generosity advisor weighs campaign capacity. Watch where they collide.
3. Budget shortfall. Ask for three response scenarios at different severity levels, then have the board rank them.
4. A hire you are unsure about. Describe the role and the finalist, and ask each advisor what they would want to know before saying yes.
5. Something you produced. Load your sermon series plan, campaign messaging, or annual report and generate an Audio Overview set to Critique for an editorial read from two hosts.
6. A real two-sided question. Generate an Audio Overview set to Debate and listen to the board go back and forth during your commute.

That gets your board built and running, and it will earn its keep on the next decision that hits your desk.

Turn the board's verdict into a source before you build anything from it.

Here is where most people stall out. Gemini Notebook builds its Studio outputs from sources, and a saved note is not a source until you convert it.

Here is the click path.

1. Run your board meeting prompt and get the synthesis you want.
2. Click Save to Note on that response.
3. Open the note and click Convert to source. (Or from the Notes area in Studio: More, then Convert all notes to source.)
4. In the left Sources panel, uncheck every source except your new synthesis source.

That last step matters more than it looks.

If the advisor documents stay checked, the video wanders back into their raw material and you end up with a lecture on leadership theory in place of your decision.

One note: this workflow lives on desktop web. Notes and convert-to-source are missing from the mobile app for now.

Use the Video Overview steering box to turn the board's thinking into a SWOT walkthrough.

Now go to Studio, then Video Overview. Before you generate, open the customization options and choose format Explainer and a visual style (Whiteboard reads well for a teaching setting).

Then paste this into the steering prompt box:

Below is the full steering prompt, plus the one verification step to run before any of this leaves your laptop.
