Crux
A personal AI on your computer you can reach from anywhere
Crux is an AI personal assistant that works across your desktop, files, and apps while keeping your chats and data local to you. It has an overlay mode that sits on your screen and helps you with whatever you're working on, no app-switching needed. You can also reach it remotely from WhatsApp, Telegram, Discord and email. Download for Mac and Windows.
Hey Product Hunt, Vibhanshu here. My friend and I built Crux.
We kept wishing our computer could keep working while we weren't sitting at it. So we built a personal AI that lives on your desktop, has your files and tools, and actually does the work, not just chats about it.
A few things we focused on:
• It has an overlay mode that sits on your screen and helps with whatever you're working on, no switching between apps.
• You can reach it remotely from WhatsApp, Telegram, Discord and email, so it keeps working when you're away from your machine.
• It's BYOK, so it runs on your own API keys or the subscriptions you already have like ChatGPT, Copilot or Grok. You can also use local models or the free ones built into the app, with 100+ providers supported.
It's in beta and still early. We're building toward making it truly proactive and easy enough for anyone to use.
Would genuinely love for you to try it and tell us how you're using it. If you hit a bug, join our Discord and we'll fix it fast: https://discord.gg/nacHyrD5W
Happy to answer anything here.
