You need an active Claude subscription to use Claude Desktop with Second Brain (MCP).
One local database on your computer for contacts, customers, payments, emails, documents, notes, meetings, hiring and interview data, and the rest of your operational history—organized so you can actually use them.
Connect it to Claude Desktop. Ask in plain language, get answers from your data, and save new information back to the same database without leaving the conversation.
Example: Claude pulling a customer record from your database—not a generic web reply.
Early pricing through April 11 · Application releases April 20
Claude and ChatGPT do have some context. They remember the conversation you are in, and sometimes small pieces of stored memory.
But they still do not know your business.
Second Brain pairs a local database with Claude Desktop (via MCP) so your assistant can work with your real records—not just the current chat thread.
They cannot see your customers, your products, your meetings, your hiring pipeline and interview notes, your internal records, or what actually happened last week. Most questions still require pasting information or re-explaining the situation before you can get a useful answer.
Built-in memory helps with small things. It cannot hold tens of thousands of contacts, years of articles, financial records, meetings and recruiting data, or structured business data. That requires a real database.
So I built one.
It runs locally and holds 100K+ contacts, 300+ articles, financial records, meetings and hiring notes, interview data, and structured operational data. When I ask a question, the system queries the data and returns answers based on real information.
Now I'm making the same system available to others.
A SQLite database on your machine with a browser-based interface to browse, search, filter, and manage your data. No cloud. Your data never leaves your computer.
Contacts, emails, phones, organizations, relationships, spend tracking, customer records, meetings, hiring and interview notes. All searchable, filterable, exportable.
CSV, ZIP, platform exports. The import pipeline handles upserts so your database stays current without duplicates or fake data.
Via MCP (Model Context Protocol), Claude reads and writes to your database. Ask questions in plain English, get answers from your actual data.
Suppression states, bounce tracking, and filtering so you can build clean contact lists from real data.
Everything runs on your machine. No subscription. No cloud dependency. No one else has access to your data.
Every license includes the full Second Brain application. The only difference is how much help you get with installation. The application releases on April 20. All buyers receive access on that date.
The full application plus a recorded setup guide. Install at your own pace after release.
The full application plus live installation support on April 20. I walk you through every step and answer your questions.
The full application plus a private 60-minute 1-on-1 session. I install it on your machine and load your actual business data.
Requires an active Claude subscription (same as the rest of Second Brain).
Free session April 22–23 for paid Hexomatic users: how to use Hexomatic well—scheduled scrapes, workflow habits, and clean exports—so contacts, meetings, hiring notes, and interview data flow into your second brain on autopilot. Same approach I use to keep 100K+ contacts and years of business context current.
Founders and business owners who use AI daily but are tired of re-explaining their business every conversation.
Agency owners managing client data, contacts, meetings, hiring workflows, and projects across multiple tools.
Freelancers and consultants who want a private, local CRM that connects to Claude.
Anyone who wants their AI to answer from real data instead of guessing.
I'm Stepan Aslanyan, founder of Hexact. I've been building and selling software products for 25 years. My second brain currently holds 100K+ contacts, 300+ published articles, customer payment data, meetings and hiring context, interview notes, and client information across three companies.
I didn't build this as a product to sell. I built it because I needed it. Every morning I open Claude and ask questions about my business, and it answers with facts pulled from my actual database. No copy-pasting. No re-explaining context—answers grounded in my data, not guesses.
It took months of iteration to get it right. The schema, the import pipelines, the CRM configuration, the dashboard. Now I want to help others skip that trial and error.
Second Brain releases on Monday, April 20, 2026. All buyers receive access to the application and their chosen setup path on that date. If you chose the self-setup license, you'll also receive the installation guide on April 20.
A one-time purchase of the Second Brain application for your own use, with the setup and support tier you selected on this page (self-setup, guided, or done-for-you). You keep the software—no subscription.
You need basic computer comfort. The guided setup option walks you through every step on screen. If you can install an app and follow along, you can do this. If you want zero effort, the done-for-you license handles everything.
A Mac or Windows machine, Claude Desktop, and an active Claude subscription. Node.js is covered during setup if you need it.
Your data never leaves your machine. There is no cloud component. The database is a file on your computer. You own it completely.
No. One-time payment. You get the application and you keep it forever. No monthly fees, no cloud bills, no recurring charges.
If you have a paid Hexomatic account, you get a free session on using Hexomatic (scheduling, workflows, exports) so your data—including contacts, meetings, and hiring or interview notes—stays flowing into your second brain. Requires an active Claude subscription.
The MCP connection works with Claude Desktop. ChatGPT does not support MCP at this time. The dashboard and database work independently of any AI tool.
After Friday, April 11 at midnight ET, the self-setup license goes to $39 and the guided setup goes to $59. The done-for-you license stays at $499.
