The Archive is designed around what Notational Velocity and later nvALT brought to the Mac: Fast, reliable search with ease of creation. As both of these applications lost their luster as macOS advanced, I left them behind in a favor of less buggy and more versatile tools. The Archive is the first application to come along that is really making me reconsider moving my note collection out of Dropbox.
The Archive owes a huge debt to nvALT. The developers acknowledge that debt explicitly. The Archive is nvALT improved.
I downloaded and played with The Archive for a few days. I found it to be a very nice and an improvement over nvALT. If I hadn’t moved my notes from nvALT to Bear last year I would definitely consider using The Archive as my notes app. For now, I’m too invested in Bear to change.
Macosxguru wrote a nice review of The Archive. I suggest giving it a read.
