Protect your email and calendar by requiring unknown senders to solve a CAPTCHA or pay a fee.

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.

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

Set up a paid contact link for your bio where visitors deposit money to email you—reply to refund them or keep the fee.

goodfaith — a paid contact link for your bio. strangers pay a deposit to email you. reply and they get it back. ignore them and you keep it. reply = free, silence = pays you. turns "please stop pitching me" into "sure, put money behind it."

Check if your chatbot complies with EU AI Act Article 50 disclosure requirements.
u/JarJarBuilds · Reddit
I built a free checker for whether your chatbot breaks the new EU AI law There's an EU rule (AI Act, Article 50) that becomes enforceable Aug 2: if you run a chatbot, you have to disclose it's AI. I kept seeing people unsure whether their setup was compliant, so I built a checker. You paste a URL, it loads the page, finds the chat widget, and tells you whether a clear AI disclosure is present. No signup, no email. Stack, in case anyone cares: Next.js, Convex for the backend, Playwright vi
