Set up your first projectBrief it.
Tell your assistant what should change, what must stay, and how you will know it works.
Build it.
Work through the task with your model and project tools. Review decisions as the work takes shape.
Check it.
Inspect the changes. Run the relevant checks. Try the result yourself, then ask for the next revision.
A workflow you can follow today. Integrated preview, diff panels, and persistent project decisions are planned; they are not in the current download.
The desktop preview
A place to work.
Room to decide.
Conversations and project tools, in a desktop host on your computer. You bring the model credentials.
Connect your provider.
Configure an available model provider with your credentials. Model requests and usage charges go to that provider.
Stay close to the work.
Direct the conversation, inspect the result, and decide what to keep. Optional SaturnBot adds scheduled work while the host is running.

Before you start
A few useful
details.
What can I download today?
The Windows x64 desktop preview, version 1.2.4. The installer is unsigned. The download section includes its size and checksum. A complete browser-hosted workspace is not available.
What does it cost?
There is no paid SaturnAI plan on offer today. The desktop preview uses your model credentials, and your provider bills its usage separately. Design Tools are free, with no paid tier. See access and costs.
Can I use my existing assistant?
Yes. Free Design Tools connect through a URL, MCP, or HTTP. That gives your assistant references and guidance; it does not install the desktop workspace.
Will scheduled work run with my computer off?
No. Optional SaturnBot needs its desktop host to stay running. Scheduling does not continue while your computer is asleep or the host has stopped.
