Recently, I was talking to an entrepreneur who shared that one of his side projects was building a personal AI brain. The goal was to process information across every area he cared about, automate repetitive tasks, and deploy simple agents to monitor different parts of his life.
I was intrigued, so I asked him to show me how he had built it and what it looked like.
It started with vibe coding in tools like Lovable and Replit, where he experimented with different AI applications. He also took inspiration from Google’s NotebookLM, which allows users to upload documents and ask questions based on their contents. Because the answers are grounded in those documents, the system is less likely to hallucinate or introduce information from outside sources.
He began by creating a central dashboard. Imagine a screen with several boxes, each displaying one to four key metrics. Every box represented a different area of his work. Clicking on a box opened a separate vibe-coded application designed around something he worked on regularly.
One of those applications was his own version of NotebookLM, but without the same document limitations. This app focused entirely on startup strategy.
Anything related to strategy, best practices, or mental models could be added to it. He could link to an article, upload a PDF, or connect a Google Doc. Over time, it became a personalized repository for everything he found valuable about building startups.
Whenever he encountered a new question, challenge, or piece of information, he could add it to the system and discuss it with the AI. Instead of searching across bookmarks, documents, and notes, he had one central place to retrieve and synthesize the ideas that mattered most to him.
Back on the main dashboard, a second box opened an application focused on product development. This app pulled information from several internal systems. It included data from Jira, such as trouble tickets and issue tracking, along with feeds from customer support, Salesforce, and the company’s roadmap management software.
Inside this custom dashboard, he could see the latest information from each system in one place. Through a plain-text chat interface, he could ask questions about the product, customer needs, support trends, development priorities, or roadmap decisions. The application could also generate graphs and charts related to the product management metrics he cared about.
Another box on the dashboard focused on financials. Clicking it opened a custom application that pulled information from the company’s financial management software, Salesforce, and other financial planning and analysis tools. It also included a chatbot for asking questions, generating summaries, and exploring the company’s financial performance.
The final section he showed me focused on industry trends. He had built an AI agent that continuously checked social media, industry websites, Techmeme, and other relevant sources. The agent compiled that information into a local database and highlighted what was trending or gaining momentum.
The app displayed graphs, charts, summaries, and a chat interface that allowed him to ask the language model questions about what was happening in the market.
Time will tell whether this becomes the standard way entrepreneurs and innovators operate. But seeing it in action, updating in real time and customized entirely for one individual, gave me a glimpse of where the world may be headed.
It was one of those lightbulb moments.
The future is an abundance of software. Some of it will be off the shelf. Some of it will be handcrafted. Much of it will be interactive, personalized, and customizable in ways that were never previously practical.
Enterprising entrepreneurs should consider building their own personal AI brains, along with small vibe-coded applications for each area of the business where they spend meaningful time. These tools can support both high-level thinking and detailed operational work.
The amount of internal and external information now available to entrepreneurs is enormous. The ability to process, synthesize, and retrieve that information quickly is unparalleled. Entrepreneurs would do well to make their most important information not only accessible, but also intelligent and insightful.
