Thanks! We do have a couple of similarities to Roam (backlinks, unlinked reference, graph view) but also quite a few things that make us unique.

First, our task management is completely different. Type tasks inside notes and they are available in your kanban/todo-list. You can also drag-and-drop tasks directly to your calendar.

Also, the way we work with blocks is (almost) unique where you can create saved searches to find blocks based on their content.

In short: simplicity, end-to-end encryption, and good design is what separates us from most tools.
