Most AI tools charge a subscription to mark up your API calls,
scatter your workflow across 5 tabs, and hold your data on
their servers.
Syntex AI OS fixes all three — at once.
It's a full desktop environment that runs in a browser tab.
Bring your OpenRouter key and unlock 300+ models — Claude,
ChatGPT, Gemini, Llama, paying providers directly at
cost. Your key is stored in your browser only. We never see it.
Pro tier is free for everyone until 100,000 users.
No credit card. No trial.
