Description
Hi HN, wanted to translate this into a more human-readable post - please see below and would love any and all feedback!What is it: A second brain you self-host and engine to compound itself and spark new ideas, from your own ideas.Why: ROI on your own knowledge, actually realize the value from your ideas. Down the line I'd love for this to evolve into a wider / shareable concept -- Haven't fully figured this out yet which is part of the reason I am posting. View the /constellation folder for the specs on that concept. (Self hosting engine is all in the repo as well)Looking forward to hearing from anyone!
