Most creators treat Substack Notes like a separate content channel.
They open a blank page and try to come up with fresh ideas every single day.
That approach is slow and exhausting.
Here's a better way.
Take content you already created and repurpose it into Notes.
I built a custom GPT that does this automatically. Here's exactly how to use it.
Step 1: Find a piece of content that performed well
Look through your LinkedIn posts, newsletters, tweets, or blog articles.
Find something that got good engagement or included a strong insight.
The GPT works with any format. You can drop in a 200-word LinkedIn post or a 2,000-word newsletter.
Step 2: Copy and paste the content into the GPT
Open the custom GPT and paste your content directly into the chat.
The GPT will analyze your content and identify the key insights, angles, and hooks.
It scans through 100+ note templates from top Substack creators like Jay Clouse, Nicolas Cole, Dickie Bush, Justin Welsh, and Taylin Johnson.
Then it matches your content to the best templates.
Step 3: Review your 10 generated Notes
The GPT spits out 10 unique Substack Notes instantly.
Each note takes a different angle on your original content.
Some will be quick tips. Others will be personal stories. A few will challenge common beliefs.
You get variety without doing any extra work.
Step 4: Copy and paste Notes directly into Substack
Pick the Notes you like best and post them on Substack.
You can post one per day for the next 10 days. Or batch post a few at once.
The Notes are ready to go. No editing required unless you want to tweak something.
Step 5: Repeat with your next piece of content
Every time you publish something new, run it through the GPT.
One newsletter becomes 10 Notes.
One LinkedIn post becomes 10 Notes.
One case study becomes 10 Notes.
You now have an endless content system for Substack without creating anything new from scratch.
Why this works
Most people abandon Substack Notes after a few weeks because it feels like extra work.
This system removes that problem.
You're not creating new content. You're multiplying content you already made.
The GPT handles the creative heavy lifting. You just copy, paste, and post.
