Yes, it's an open source software called Dnote [0]. I wrote it two years ago and have been using it since. The two main features are: * putting in new information without switching environment * getting automated weekly email digests Like you, I wanted to avoid building habit around a separate app because that would require me to switch environment every time I want to write something, thus losing context of my current task. So I made Dnote work as a CLI, browser extension, IDE plug-in. While I'm not sure exactly why you want an email spaced repetition, for me, the reason was that I never looked back at my past notes. The solution to this negligence was to automate the spaced repetition via weekly email. I suspect we are trying to solve a similar problem. Hope my software can help.
