Brainbox - Give your AI Agent a safe home

AI can work for you - and now it can even shop and pay for you. Agents may have access to all your data and full control of your system. We believe these agents need broad permissions and the freedom to work efficiently, but only with the data and control you choose to grant them. We give the autonomous agents of your choice (Claude, GPT, Ollama, …) a safe home.

Stop clicking. brainbox builds the spreadsheets, the report, the slides, the presenter notes, even a briefing video - all while you're gone. What's left is the part that always needed you: deciding whether it's right, and doing the work that matters.

Germany calculates how long its own paperwork should take. For this stack of forms: 37 working days. Brainbox did it in 13 minutes. No API - it just fills the same forms a human would, at scale. What would you do with your day if you never had to fill out a form again?

Anthropic's frontier model Fable 5 lost 0-5 to a chess program from 1991. Then it stopped playing and started building. We ran a session in brainbox with Fable 5 and gave it one task: produce a video that explains itself - by autonomously installing a chess program, playing against it, and showing its work. The results were intriguing. 🧵1/5

No joke - my 7yo and his friend built their own video games, then debugged them until each one played exactly how they wanted. I was amazed - they typed only a few things. Mostly, they just talked, via brainbox's local voice control (Whisper). Every session runs sealed, and I can approve each step. Safe both ways: my kids, and my machine. Here's what the first one looked like. Today they've built many more. Football, card games, drums. I wish I'd had this when I was his age.

People used to debug code. Now people debug conclusions. That is a harder job, and a far more human one. AI has quietly removed code errors and the pipeline that used to die now runs to completion. We can re-run a pipeline and check whether it works. Comparing pipelines from mid 2026 with those from a few years ago, we are starting to see the problem shifting quietly: from "does not reproduce at all" to "technically reproduces, but is not plausible."

🚀 AI agents can do real work now. Which is exactly why I won't let one loose on my actual computer: Give every AI agent its own computer. We have built an operating system that makes autonomous agents work better: they operate programs, write code and pipelines, fill in forms, make your job easier. And because every session is sealed inside its own virtual machine, your system and your data stay protected.
