I've been looking for an Evernote replacement that was more ahem concise. I've been using Evernote to help plan experiments and track papers, but it can't seem to get out of it's way... particularly when trying to share a notebook with collaborators. Honestly, the biggest downside that I see with Quiver is that it is Mac only. This isn't an issue for me, but might be for some collaborators.

Then again, the alternative would be to use some other tool or shared Google Doc or something like that, so Quiver probably isn't too much of a hassle in that regard.

You should be able to script writing new data to a note for simulations / plots, given that the notes are JSON files. I love that the DB is an easy to read / edit / backup set of JSON files.
