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…

Hello Aria▲163I built HelloAria because every task manager I tried required too many steps to do something simple. The core idea: say "remind me to review the PR tomorrow at 10" and it creates the task, sets the reminder, and files it. No forms, no manual input. It works on iOS natively and also through WhatsApp, Telegram, and email — so you can capture tasks from wherever you already are. Tech stack: Swift/SwiftUI on the client, with NLP handling the intent parsing and entity extraction from natural language input. Looking for feedback from the HN community. What would make this actually useful for…

LIAMfree tier▲111Hi HN, yesterday I missed a meeting and spent most of the day sending ~35 emails. That kind of inbox + calendar admin has been draining my time for a long while, so I built LIAM to fix it. It helps with: - Drafting replies in your tone (honestly a bit scary how close it gets) - Scheduling meetings and handling the back and forth - Prioritising important threads and organising the inbox Important: LIAM doesn’t send anything without approval. I’d love feedback on what you’d actually trust an email agent to do, and which email workflows you’d automate first. You are more than welcome to roast…
