Two years ago, I built a simple command line interface to instantly write down notes in a JSON file. I have been using and building it ever since, and now it has become more mature with useful features such as: * Sync across multiple devices * End-to-end encrypted backups * Weekly email digests for spaced repetition * Web client, browser extension, IDE plugins The whole thing is open source and optimized for command line usage. What I have noticed in the past years is that this tool can be used to build a personal knowledge base. The reason is that it provides a way of quickly capturing new information without switching environment. Also, it sends you automated email digests. (i.e. if you are in a command line, just jot down your thoughts and get email reminders later). I wanted to share the progress I have made so far.
