Substack note generator (Claude AI artifact/app)
Don't pay for AI writing tools when you can build your own in Claude
Anthropic just supercharged their AI artifacts for Claude.
Now you can create AI apps right in your Claude chat. Just by talking to Claude like you normally do.
You can publish these apps and share them. Anyone who uses them burns their own Claude usage limits, not yours.
Within 10 minutes, I'd built something that turns any Substack post into 20 viral-ready notes.
Nothing fancy. Just a practical tool that allows me to easily extract more value from my newsletters.
But first, let me be clear about something
I don't believe in 99% of AI writing tools. Quick generation-style tools for newsletters, social media posts, etc.
They're usually absolute shit. Don't pay for them.
Why? Because they have zero context about who you are.
And if you know anything about me, it's that context is everything.
These generic tools can't access your voice, your archive, your frameworks. They can't tap into the depth you've built in your Claude or ChatGPT projects.
So why did I build this tool?
Because this is one of the rare exceptions where a standalone tool actually makes sense.
It's not trying to write FOR you. It's extracting FROM what you already wrote.
When you paste your Substack post, all the context it needs is right there. Your voice, your ideas, your insights—already baked in.
The tool just reformats them into 20 bite-sized notes.
No generic AI writing. Just your own content, restructured.
The tool does ONE thing perfectly
Paste your newsletter.
Click generate.
Get 20 notes, each 50-75 words.
That's it.
Built with 8 proven note formats that actually get engagement (Contrast format, List structures, Personal discovery, Problem-solution, and 4 more).
Every post you've written can become 20 pieces of promotional content.
