how would you use Anki deck if it is collaborative?

Hi everyone, sorry if this is something that’s been asked before, or if it’s a bit of a beginner’s thought. I’ve been wondering about this for a while but wasn’t sure how to put it into words.

How would you go about making an Anki deck that’s actually collaborative? Like, something that you can load with premade decks at the start… but later on, you and maybe a study partner, teacher, or friend can keep adding new cards to it as blind spots appear. Almost like an evolving shared memory.

And maybe when you need to focus, you can filter or tag certain cards for super-targeted review sessions.

Would this sort of deck even be useful for you? Or do you think Anki works best when it’s kept private, individual, and tailored only to your own brain?

I guess what I’m really wondering is… would the learning experience change if an Anki deck was truly collaborative? Would it help? Or would it somehow make things messier or less effective?

Sorry if this is a strange question. Just curious how others think about this.

Thanks for reading.
