What Happens When You Can Actually Talk to Your Database

I imported tens of thousands of contacts, payment records, meetings, support tickets and newsletter subscribers into Second Brain. Then I started asking questions.

For most of my career, I wanted the same thing: one place where all my data lives together, so I can ask it questions and spot patterns. Like those scenes in movies where someone walks up to a screen, asks a question, and instantly gets the answer pulled from everywhere. One window, everything connected.

Reality was the opposite. Every tool I use keeps its own version of reality. Stripe knows who paid. Substack knows who reads my newsletter. Google Calendar knows who I met with last Tuesday. My CRM knows... whatever someone remembered to type into it six months ago.

Now multiply that by several businesses, each with its own Stripe account, its own calendar, its own contact list, its own CRM. The data doesn’t just live in different tools. It lives in different worlds. A customer in one business might also be a client in another, and I’d have no way of knowing unless I happened to remember their name.

None of these tools talk to each other. And I got tired of it.

So when we built Second Brain, the first thing I did was dump everything into it. Every contact, every transaction, every subscriber, every meeting. All into one local database on my laptop. Then I connected it to Claude and started asking questions I’d never been able to ask before.

I finally know the relationship between my newsletter and customers

Here’s a question I couldn’t answer until I put both datasets in the same database: what’s the relationship between reading the newsletter and becoming a customer?

Not just the overlap. The sequence.

Did people subscribe to the newsletter first and then become customers? Or did they buy first and subscribe later? How long between subscribing and paying? Are long-time readers more likely to stay on a paid plan?

No single tool gives you this. Your newsletter platform tracks opens and clicks. Your payment processor tracks charges. But the timeline across both? That only exists when the data is in one place and you can actually ask questions across it.

In a traditional CRM, you’d need to connect your payment system to your analytics platform to your email tool, set up automations, build reports. In Second Brain, I asked the question and got the answer in about five seconds.

I actually know who I’m talking to

You’re about to get on a call. You check the CRM. You see a name, a company, maybe a deal stage. That’s it.

What you don’t see: this person’s payment failed twice last month. They filed a support ticket that’s still open. They unsubscribed from your newsletter.

You walk into the call thinking everything is fine. It’s not.

I used to do this all the time. Now before any important call, I ask Claude: “What do I know about this person?” It pulls their payment history, subscription status, newsletter engagement, calendar meetings, any notes I’ve saved. All in one answer.

It takes ten seconds and it completely changes how I approach the conversation. I’m not guessing anymore. I’m prepared.

You can ask questions nobody built a dashboard for

This is the thing that changed my thinking the most.

Dashboards are great, but they only answer questions someone already thought to ask. They’re static. Someone designed them last quarter based on what seemed important then.

That shift matters more than any feature. You go from consuming pre-made reports to interrogating your own business in real time. You become curious about your data because the cost of asking a question (before it was a new custom report) dropped to zero.

It works both ways

Everything I’ve described so far is about asking your database questions. But you can also tell it things.

After a call, I say “save this ….. about…..” It goes straight into the database as a note, linked to the contact. I can paste a screenshot of a chat and ask Claude to create a records based on that. I can paste a meeting summary and say “add this to the customer’s record.” I can say “this person is now the CEO of Acme Corp” and it’s done.

This is the part that makes it feel like that movie scene I mentioned at the top. You’re not filling out forms. You’re not clicking through dropdown menus. You’re having a conversation with your database, and it works in both directions. Ask and get answers. Tell and it remembers. Meanwhile still having the direct access to your data using Second Brain interface.

It keeps getting better

We ship updates constantly. Right now Second Brain has 21 import sources: Stripe, PayPal, Notion, ChatGPT conversations, Evernote, Asana, Jira, Trello, Obsidian, Google Calendar, Google Contacts, Substack, email archives, CSV uploads, and more.

We just added zip file imports (up to 200+ doc files at once), and improved database cleanup tool. More import sources are coming.

Here’s what I’ve learned building this: each new import source makes everything else more valuable. Connecting your Stripe data is useful. Importing your Stripe data, CRM and subscribers is powerful. Import your Google Calendar data on top of that and now you can see the correlations.

It compounds. The more data you bring in, the more questions you can ask, and the more patterns you find that were always there but invisible.

Start with one import. Whatever you have. A contacts CSV, your transactions, your newsletter subscriber list, multiple spreadsheets. Get it in, connect Claude, and ask your database something you’ve always wanted to know but never could.

You’ll be surprised what’s been hiding in your own data.
