So you're telling me Stremio let's you stream anything from any platform, for free?
This is based on torrents, this is terrible advice for the basic user because they won't be using vpns to mask anything. There's literally no solution that will suffice for OP if they're looking to be safe.
Let me sleep for centuries while pure evil kills everyone.
No there's nothing like this. You'll still have to search and download stuff before watching it.
You can have your setup auto download lists and try to mimic things. But you'll never be able to have the mindless scrolling like Netflix. Don't let anyone convince you there's a solution out there currently.
Netflix UI, sure. Plex does a great job with showing content from all over. But it's still not the same cohesiveness.
