I really wanted to love this one. It's being marketed by AppSumo as an alternative to Evernote, which it is clearly not. I find the UI a little bit disorientating and I'm disappointed by the lack of iOS app. I would love to be able to have notebooks that would hold notes on the same topic in card format. Much better than the endless string of notes/knowledge under a collection. On the plus side, the AI integration is a nice upgrade from other tools. Undecided if I should just ask for a refund or wait for this tool to mature into something more effective.
