I use it on a Windows PC and a Mac without the filtering, because I use Gentech for filtering, and for me it's great and I view as a necessity. In regards to what to said about in-app browsing, if it behaves like google or other search engines then yes it would be filtered and this does include youtube but it's a very minimal filter because all they do for youtube in particular as an example, is set youtube to restricted mode. Webchaver's filtering works at the internet-domain level unlike other filters like gentech and netspark, meaning that all internet activity on the device will be accounted for and if it behaves like a search engine, that will be additionally filtered if you have it enabled. Even if you don't have it enabled, when webchaver takes screenshots they record the internet domain address of the page you're viewing if it's on the internet, and if not then the app on which you're viewing it and that's included in the information of the screenshot for your ally to see. And while it's true that the AI sometimes doesn't pick up inappropriate images that are not explicitly p, if you search up something inappropriate, the AI will be able to classify it as suspicious and notify your ally, because your search terms (the words you put into the search engine to look up) will be run through the AI too so even if it failed the identify the image as suspicious, it would be able to with your search terms.
The bottom line is that you should get it but without the filtering, because it's free if you get through the knas based accountability (the details for how to set that up properly are in my signature). The filtering sometimes conflicts with other filters like Gentech, which it did in my case which means you won't be able to access the internet with both of them, and I believe that you can't add filtering to your webchaver package if you get through the free method. I would also say that pricewise, truple isn't the best thing to get even though it does offer a few more features, because it's close to price to gentech and it would be better for you to have gentech and webchaver than just truple alone, unless you want to get truple and gentech which would be more expensive. And in regards to getting a filter since I recommended to get webchaver without the filtering, I would recommend getting gentech.
