How it works

Internet is needed once, during setup. After that, never.

Buy the assistant you want and receive an activation code.
Download the PAi setup program ? one file, about 40 MB.
Enter your code. PAi checks your computer's memory, disk space and graphics, then recommends the AI that suits it.
Choose your AI engine ? DeepSeek, Qwen, Llama or Gemma.
The AI downloads. Several gigabytes, once, because it runs on your machine rather than a server. It resumes if interrupted.
Done. PAi installs it, tests that it starts, and creates your desktop shortcut. Disconnect the internet if you like.
