Thanks for the interest!

Not yet, currently most of our users bring their own sync (Dropbox etc.), so if you edit the same document in real time that might create conflict copies.

We're working on a sync service with end-to-end encryption (for convenience, completely optional), and we might improve it to support real-time collaboration in the future.

Will there also be an option for client-side encryption without using your sync service?

We might provide a plugin in the future to achieve this.

Right now I think the closet thing is to use set up an encrypted folder with a third party app to use with Obsidian.

I just tried the beta. Beautifully done @erica
