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

I built a Chrome extension that rewrites emails for different cultures — would love feedback on the website Hey everyone, I've been building MailPolish — an AI tool that polishes emails, letters, and texts so they sound right for different cultures.

It works as a Chrome extension inside Gmail, a Gmai

Reintroducing - an open-source, Gmail-Discord hybrid email inbox for your Resend domains. I've used Resend for every project I have made in the last 2 years. But every time someone replied to any email I sent, that reply went into a webhook payload and then basically disappeared. So I built the client half. You paste your Resend API key, inboxes imports your full history, and you get an actual inbox for every domain - threading, full-text search with from: / has:attachment operators, undo send, scheduled send, snooze, rules, shared aliases, roles. Discord-style sidebar, Cmd+1-9 to switch domains. Gmail shortcuts (because why not). Agents get to work alongside you in your inboxes too (but not too much). There's an MCP server for Claude Code, Codex, opencode etc. Your agent can read, search, and write drafts, but 'only' with your direction. Draft-first by default so it's opt-in only on actual replies/sends from the agent (has to be toggled in the app). $5/mo per o
