Building a second brain has always been the ultimate promise of productivity, but for many of us, it felt more like a chore than a superpower. There is no shortage of PKM tools capable of storing information and processing it, but most of them seem intimidating due to the manual work involved.
After months of experimentation, I finally closed this gap and created a workflow where two tools don’t just coexist: they collaborate. Here’s how I combined the reliability of NotebookLM’s sources with Claude’s analytical depth to create a personal knowledge system that finally feels alive.

Create a notebook in NotebookLM
Process all relevant information
Once my local folder is full of these Claude-generated Markdown files, the next step is to move them to NotebookLM. This is where Google’s AI note-taking tool becomes the anchor of my research.
I start by creating a new notebook, like Vietnam Trip 2026, and the upload process is smooth. Since Claude had already done the heavy lifting organizing my itinerary and toddler travel tips in Markdown, I simply dragged and dropped this entire folder into NotebookLM.
But I don’t stop at my own notes. I grab URLs from travel blogs or official visa sites and paste them. I also found a few high-quality videos, like “Hanoi Walking Tour” or a “Traveling Vietnam with a Toddler” vlog and removed the links.
Sometimes a stray thought comes to me that isn’t in a file or link – like a specific budget reminder or a note about a friend’s recommendation of Da Nanag. I will use the Create New Note function directly in the interface to enter them manually.
It’s like having a digital notebook that immediately becomes part of the laptop’s total intelligence.
Using NotebookLM at its best
Unlock the full potential of your PKM system
Once this notebook is complete, NotebookLM becomes a beast of a research partner. True power lies not only in organization but also in speed.
I can ask very specific questions about my data and get informed answers in seconds.
- Based on the Sapa and Ninh Binh YouTube vlogs I uploaded, which specific paths are stroller-friendly and which require a carrier?
- Cross-check my hotel reservations with the neighborhood guides: are there 24-hour convenience stores near our stay in Da Nang for emergency milk or diaper shopping?
- What are the best indoor rescue activities in Ho Chi Minh City if we are caught in a monsoon downpour?
- Summarize day 4 of my itinerary in a one-page briefing document, including our flight number, hotel address in Vietnamese for the taxi driver, and two nearby vegetarian dinner options.
The possibilities don’t stop at text. For example, I wanted to present the final plan to my family so that everyone was on the same page. Instead of creating a slideshow manually, I simply had NotebookLM generate a slideshow directly from the studio panel.
I began to apply this NotebookLM logic to almost every aspect of my professional life. I use the Claude and NotebookLM combo for my investment analysis, learning Python, setting up self-hosting services, and much more.

The power couple
The true measure of a second brain is not how much information it contains, but how effectively it serves your production. By combining NotebookLM and Claude, I don’t have to face any compromises in my PKM system.
If you’ve been waiting for the moment when AI goes from a novelty to an essential part of your workflow, this is it. Of course, this is just my PKM system. Yours may be completely different depending on your needs and workflow. Don’t be afraid to try new, creative methods to get the most out of this pairing.
