GPU and RAM consumption is an information that is up to the developer of the installer to add. Also on which GPU's or OS the app is running. If you can't find it in the app description or if there are no post about it, the only way to figure out is having a look at their github page.
The link on pinokio.co leads you to the github page of the pinokio installer. Many projects there provide a link to the project on that page.

If there is none, click install.js on that page and have a look at the first command. The clone command. It contains the link to the project. On that page you should find all information you need.
The storage depends highly on the downloaded models. Models you need for PDF's aren't very big though. More or less you can say an app has a size of 5-10 GB approximately plus the model you need for it. On the majority of the github pages of that projects, you will find a huggingface link that leads to the models. Just have a look how big they are.
I think Unlimited OCR -Searchable PDF sounds like the right app for you. This app is installer and project on one page. So it's enough to click that link on pinokio.co and have a look at the github page.

Many apps have it directly in their description or their Announcements if they require an api key or send data to an external API. If not, you would also find that information on their github page.
