Started at an @AnthropicAI Hackathon in February. Today, Matrix OS (@joinmatrixos) is live, giving a computer for your AI agents so they don't die when you close your laptop. But for me, the story started much earlier. When I was six, I could barely read, but I would spend hours clicking through Windows XP just trying to understand what a computer could do. I think I’ve been obsessed with that question ever since. Over the past 3.5 years, I’ve built intensively with AI. I kept seeing the same pattern: the models were getting incredibly capable, but the computer around them was still designed for a human sitting in front of a screen, clicking around and typing. I joined forces with @NimaNaderi2004, we kept building, and today we’re opening signups, shipping Matrix and our desktop app, and announcing our first angel round, backed by @alexwikstrom, @bakkermichiel, @salar, @Founder_Ash, @mattiasmiksche, @fbjork, @sidk_, and @engineerrprompt among others. Since we are backed by the best, we brought @xyhstruggler , @Elibethmarch and @valeriewistrom to help build and achieve one mission. Our mission is to give everyone a Personal Cloud Computer 💚 PS: We’re also hiring engineers in Stockholm and around the world. If rethinking what a computer can be; sounds like your kind of problem, come build with us!

Last night, we explored AI Safety and Agents, how much control we should give them? I absolutely loved the energy in the room, all the great questions and engagements and being on the panel with Mantas
Vilnius, you were amazing! 💚 30-minute panel - turned into 75 minutes. That's how good the crowd & conversations were. Huge thanks to everyone who joined us. Can't wait for the next one! 🐰

welcome to the club Duet 🤝 So far, Matrix is the only open source full agentic computer and assistant in the market that works with any model you want and is available in EU, US and globally, no waiting list or restrictions give it a try matrix-os.com/
We’re opening a research preview of Claude Duet, a new app where Claude works as a proactive agent. It comes to you with what needs your attention, completes tasks you ask of it, keeps working when you step away, and checks with you before it acts on your behalf.

I believe everyone in AI rn should spend learning about AI Safety more seriously than before happy to be with Mantas in Vilnius next week to discuss these
Vilnius engineers, this one’s for you 🇱🇹 What happens when AI agents get real access? Systems, data, decisions, communication. We are hosting an engineering evening with @thehamedmp + Mantas Lukauskas from @Hostinger 📍 Vilnius 🕕 18:00–21:00 luma.com/sk1bo3gs

OpenAI Dots: always-on agent + cloud computer. Also: Pro users in the EEA, UK & Switzerland wait. If you want the computer, not the lock-in: → bring Claude / Codex / Cursor / Gemini CLI → Matrix Cloud or your own Linux VPS → always-on on Builder/Max @joinmatrixos

I'm happy to see @OpenAI also joined our vision for everyone will have a Personal Cloud Computer using their newest product Dot. Tl;dr of Dot, Grok bot, Muse and Matrix: > Build agents > Work 24/7 > Connect to your tools > Access from desktop and mobile What we do differently in Matrix is being the Model agnostic, open source alternative to them you can access from anywhere (even EU and UK, since Muse and Dot are not available) and use any model/subscription you want, without being bound to one provider. These providers and models will come and go, your computer will stay the same. Matrix OS is the computer for you and your agents to share, work and collaborate. Excited for seeing where everyone will land in PCC world and well done to Dots team for such a great execution. Check out this comparison page on our website and use Matrix today in EU and UK.

great to see claude also caught up to Matrix for anyone who wants to use cloud coding environments with a fixed cost, use Matrix at matrix-os.com a cloud computer for ai agents, cli, mcp, ... included and it's multi-provider
Cloud sessions are officially available and out of research preview! They let you keep Claude Code working, even when your laptop is closed. Existing subscribers get a one-time credit to try them: $100 on Pro, $250 on Max.

“I’ll just set up a VPS” Then come persistent sessions, browser access, auth, routing, backups, and updates. Matrix Cloud puts those pieces together for you 🐇 What would you ship with 100 hours back?
