We're building the AI workspace that serious people have been waiting for.
We started Open Brain because we were frustrated. Every frontier AI model has different strengths — but using them meant juggling six different apps, losing context every time you switched, and spending more time managing tools than doing real work.
Meridian is the answer to that frustration. One workspace where you can @mention any model, compare their responses, route intelligently, and build with the full power of AI — without the chaos.
We don't have a favourite AI. We believe different models excel at different tasks, and the best tool for serious work lets you use them all — intelligently.
Not another chatbot wrapper. Meridian is a workbench — with projects, rules, memory, routing, and collaboration built for the way ambitious teams actually work.
Our code is on GitHub, our legal docs are public, and our roadmap is open. We believe the best AI tools are built in the open, with users as partners.
We don't train on your data. We don't sell your data. Your prompts and conversations belong to you — full stop.
Serious software for power users — not another chatbot wrapper, but a genuine AI workbench built for the way ambitious teams actually work.Open Brain — Meridian Design Principles
