Zero▲845Hi HN, I’m Nizar, and I’m building Zero (https://0.email) — an AI-powered email client that manages your inbox for you. Email hasn’t changed in decades, even though the way we work has. The average knowledge worker now spends close to 30% of their week on email, constantly reacting, replying, and sorting through noise.

Hi HN :) really excited to share this with you. 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.
