One rule decides everything here: free is everything a launch needs to run. Paid is the optimisation on top. A fresh install also runs the full paid set free for 14 days. Prices are served by our checkout server, in US dollars.

Every fresh install runs everything free for 14 days — no key, no payment details. After the trial, the free edition above keeps working forever, and a key is only for turning the paid features back on.
macOS and Linux:
curl -fsSL https://oaica.com/install.sh | bash
Windows: download the installer from oaica.com.
