However, I recently begun moving towards a command line workflow using helix etc for my coding, and wanted to port my notes over to this workflow.

zenkat is a project that aims to give back some of the 'superpowers' that note-taking apps give you, like tags, knowledge graphs, and so on, while being FOSS (GPLv3).

Super happy to hear your feedback as it helps me improve the project, or to take pull requests.
