RV Park SAAS So that I’ve used wispr flow to help write this so it’s a disclaimer. I recently built myparkoffice.com , and to be honest, it started as total "AI slop." I asked AI to identify a "pen and paper" industry that was ripe for AI disruption. When it suggested RV parks, I thought I’d struck gold. A low-tech niche with clear inefficiencies? Sounds like the perfect solo-founder dream, right? I leaned heavily into AI to build the entire thing, treating it more like a fun experiment th

I found out that numerous apps are rejected every year due to constant changes in the policies of the App Store and Play Store. So I built Veravo. You tell it about your app, and it tracks

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. If a sender is willing to do a bit of work to reach you, the message is more likely to be worth your time and the sender more likely to be real. The work is a traditional captcha. You can also set a pay-to-deliver amount if you want more friction. The proceeds of the delivery payment after transaction costs go to the Internet Archive and the EFF. The tool curr
