PrivateGPT FAQ

Is PrivateGPT free?: Yes. It runs on your own machine, so there is no usage-based cost either.
Do I need to install anything or write code to use PrivateGPT?: It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
Does PrivateGPT work on a phone?: No. It needs a computer.
Can PrivateGPT run offline?: Yes. Everything happens on your own machine, so your data is never sent to an outside server. That makes it usable for material you cannot share externally.
Can I use PrivateGPT commercially?: The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
