Where is the demand coming from?
Leans on the founder

What it is
A Substack publication documenting first-time founder lessons and mistakes while building in public, centered on creating products without leaving ChatGPT. The post appears to be a narrative/educational essay rather than a shipped product with external adoption signals.
The one thing to knowNo corroborated traction, monetization evidence, or product differentiation detected; this reads as founder blogging about process rather than a wedge-ready market opportunity with user demand.
