Hey Hacker news, Over the last couple months, I've been hacking with a friend on an email client for gmail that is similar to superhuman. A little backstory, we think that superhuman, in it's current implementation is vim-like. We hope to mostly match the performance and usability there and expand it into something more vscode-like. Looking for feedback and suggestions!

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…

Hi all! Excited to share rss2newsletter after completing dev work for the initial release. The idea for this project came out of necessity, as I wanted to share my articles via email newsletter. I was looking for a super minimal, lightweight, and open source solution, and when none existed, I decided to create one. For any sizable number of email recipients, a popular platform like Mailchimp will easily cost you hundreds or even thousands per month in per-contact fees. rss2newsletter, on the other hand, allows you to use Amazon SES, so you can reach your audience at pennies on the dollar.…
