Omnia OS — Email Reimagined
I just shipped something I’ve needed for years - a more efficient email client. I finally built Omnia OS because my inbox turned into a landfill of AI-generated noise. If you're going to email me going forward, I suggest including a more compelling subject and opening line, otherwise all emails from unknown people will not make it to my inbox. AI draft-suggestion tools never solved the real problem: finding the messages, files, or company I actually need to follow up with. After securing AI systems for a living, I know how easy it is to weaponize prompt injection, so bolting AI onto email…

What it does
Omnia OS is an email client that quarantines unknown senders, groups mail by company, and lets you bulk-clean in minutes. Local-only, no AI processing.
Omnia OS is a desktop Email client that keeps your inbox clean without relying on AI.
Omnia OS isolates unverified senders, groups email by company, and helps you clear a backlog in minutes. Unknown contacts land in review queues. Decide who joins your inbox. Threads, files, and people from each organization live together. Omnia OS lives on your machine, keeps suspicious domains isolated, and makes phishing stand out before it hits your team. All data stays on your device, Omnia never sends it to the cloud. Mitigate phishing emails by isolating unknown domains. i.e. rnicrosoft.com would need separate approval to join your inbox. Version 1 supports Gmail email accounts and is currently only available on macOS. All of your data is stored locally on your own device, nothing is…from omniaos.co

Zero2025 · 0.email · ▲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…

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
