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. It’s become one of the biggest productivity sinks in modern work. At the same time, AI has transformed how we write, plan, and collaborate — yet our inboxes are still stuck in the past. I built Zero to fix that. Zero automatically prioritizes, organizes, and even…

Supamail AI▲214I run multiple projects and D2C brands, which means I manage 6 different Gmail accounts and easily get 100+ emails a day - team updates, invoices, customer queries, newsletters, OTPs… everything mixed together. After missing a few important emails that actually cost me money, I realized the problem wasn’t the number of emails, it was how hard it was to make sense of them. So I built Supamail, an AI-powered inbox that helps you read less and understand more. Here’s what it does: - Emails in last 24 hrs shrink into clear summaries, smart categories, and easy replies so you never feel…

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. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels…

Dan Ariely and I are looking for ways to help people with high email load. One idea was Shortwhale, which we've tested for a few months now. The idea is super simple: It's a place to tell people how you prefer email and it offers a simple contact form that adds the necessary structure to email. Although technically trivial, it works extremely well for Dan. We have ideas on how to expand this but first we'd like to know if someone else might find this useful too (we know that this is only a solution for people who get tons of (unsolicited) email). Underlying to all of this is the idea to put…
