Hi HN, The one thing AI reliably does is generate noise. Half the tools I see launch are just machines for producing more noise across more channels. And people are starting to see this in the form of emails in their inboxes as spam filters are struggling. There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels have been abused like this. Captchainbox applies the idea of proof-of-work to email.

How I've gotten 1.5M reddit views and thousands of users across every product I've launched I've launched 8 products in the last 18 months and I'm now building a marketing tool full time. Along the way lovable invited me out to their HQ at 18 to demo one of them, I've run growth for a YC backed company, and got into Antler. But none of that is the point. The point is that most people assume the products that got traction had some secret in the product itself. They didn't. The product barely
