How to Build a Personal Knowledge Base That Works Like a Second Brain
Using ChatGPT + Hexomatic
Let’s be honest: ChatGPT is brilliant, but without context, it’s like hiring a genius intern who doesn’t know what business you’re in. Every time you start a new conversation, you're reintroducing yourself.
Even with web browsing enabled, ChatGPT still struggles with finding relevant, up-to-date, or deep information about you or your business.
But what if ChatGPT already knew your website, your blog content (or the exact piece you need), your offers, your public reviews, what others say about your brand — even how you talk to your customers?
That’s where building your “Second Brain” comes in.
The idea is simple: collect the public digital footprint you already have and use it as fuel to make ChatGPT smarter, more useful, and more personalized.
And yes — privacy matters. So think twice about what you share. You’ll probably want to skip anything internal or sensitive. The focus here is on public content — things anyone could already find online — but now you’re making it actionable.
Step 1: Collect the Right Public Data
Start with what’s already out there about you or your business:
Your and your closest competitor website (home, about, services, pricing pages, FAQ)
Your blog or newsletter archive
Google search results for your name, business, or products
Reviews on platforms like Google, Trustpilot, etc.
Your bio pages
Articles, interviews, or podcasts where you’ve been mentioned
Event listings or public case studies
Common customer questions (from forums, Reddit, emails, etc.)
Step 2: Automate the Collection with Hexomatic
Doing this manually would take hours — so here’s where Hexomatic saves the day.
Examples of automations:
Scrape your and why not your close competitor website — pull all the text from your About, Services, or Blog pages
Automate Google searches — e.g., “Your Name + interview”, “Your Brand” or “Your products”
Extract content from article links — grab the full text from any press or guest post
Collect data from podcasts and interviews — use Youtube Transcript Scraper
Classify data and sort the data
You end up with a clean, structured files that contains the essence of your digital presence.
Step 3: Feed It to ChatGPT Like a Pro
Once you have your knowledge base, here’s how to use it:
Paste relevant chunks directly into your prompts
Upload context files to ChatGPT (PDF, .txt, .csv)
Reference them when building your own GPT or working inside custom tools
For repeat tasks, save pre-filled prompts that include your core data
Some Prompt Ideas You Can Improve and Try:
“Using the info from my website and reviews, write a cold email pitch …”
“Based on our testimonials, create a 3-slide pitch deck draft for a client meeting.”
“Summarize my blog tone and write a tweet in the same voice.”
“Generate a few FAQ answers based on our Google reviews.”
“Create 3 variations of our About page copy optimized for different audiences (e.g., agencies, startups, enterprises).”
“Draft a support reply to a common question about our pricing using our existing tone of voice.”
“Based on our case studies, write a short success story for social media”
“Turn our Services page into an elevator pitch I can say in 20 seconds.”
“What objections do you think prospects might have after reading our reviews? How should we respond?”
“Using our latest blog posts, generate a 5-part email sequence for a nurturing campaign.”
“Using this scraped competitor page, how can I position our product differently?”
“Compare our homepage with [Competitor X]'s — what messaging do they use that we don’t?”
“Analyze [Competitor X]’s pricing page and suggest how we can better communicate our value.”
“What services or features are they highlighting more than us?”
“Based on [Competitor X]'s blog strategy, what topics should we be covering next?”

Final Thought
Your digital footprint is already out there — scattered across websites, reviews, podcasts, and posts.
But it’s only valuable if you can use it.
With a little help from Hexomatic, you can automate the messy part and give ChatGPT the exact context it needs to actually sound like you.
