Features
Everything you need, nothing you don’t
Built to be fast, private, and genuinely useful from day one.
Private & local
Runs strong AI models right on your PC — fully offline-capable. Your chats and files never leave your computer.
A brain that grows
It reasons from first principles, remembers what matters across chats, and refines its own knowledge over time. Build custom brains for any role.
An agent with its own computer
A built-in, firewalled sandbox machine the AI can actually use — browse the web, write & run code, install tools, and finish real tasks. Watch it live.
Deep reasoning & research
Deep mode attacks a problem from several angles and fuses the best answer. Autopilot researches a goal on its own, cycle after cycle, until it lands.
Pro models on tap
Subscribe and Claude, GPT & Gemini are built in — no API keys, no setup. Or plug in your own key. Or just run free local models. Your call.
Voice, images & your phone
Talk to it and have replies read aloud, generate images, run scheduled tasks, plug in MCP tools, and chat with it from anywhere over Telegram.
Pricing

FAQ
Questions, answered
What platform does it run on?
Windows 10 and 11 (64-bit). Download the installer, run it, and the AI model downloads itself on first launch.
Is it really private?
Yes. With local models, everything runs on your own machine and nothing leaves your computer. There are no accounts and no telemetry. (If you use Pro or your own API key, those requests go to the model provider — your choice.)
Do I need to pay anything?
No. The full app is free — agent, brain, deep reasoning, the works — running strong local models. Pro is optional: it adds Claude, GPT & Gemini built in, with no API keys to manage.
What is Ziusudra Pro?
A $20/month subscription that gives you top cloud models (Claude, GPT, Gemini) inside the app with zero setup. After you subscribe you get a key — paste it into Settings → Ziusudra Pro and pick a Pro model.
What can the agent actually do?
It has its own isolated sandbox computer it can use — browse the web, write and run code, install tools, and complete real multi-step tasks. You can watch it work live, and it stays walled off from your real PC.
Can I cancel Pro?
Anytime — manage or cancel your subscription from inside the app (Settings → Ziusudra Pro → Manage subscription) or just reply to a billing email. Billing is handled securely by Stripe.
