Download the beta.
Free, for Windows 10 and 11. Not a trial.
Nova Helix Free is out as a beta. It is free, it does not expire, and it is far from perfect. The developer would rather hear about the rough edges than not.
Pro and Ultra models are not published yet, so a paid plan cannot be used today. The plans page has the prices and the launch offer.
The download is a zip rather than an installer, and it is not code signed, so Windows will warn you the first time. Unzip it anywhere and run Install.cmd.
The application is a small download. Its models are about sixteen gigabytes, and Nova Helix fetches those itself: open Settings, then Downloads. You can stop and resume, and nothing has to be placed by hand. The model list is published, with a checksum for every file.
What you will need.
Operating system
64 bit Windows 10 or 11.

Any ordinary laptop. 16 GB is comfortable; below it, a smaller model. What Free wants.

About 16 GB for Free’s models, fetched inside the app.
