I have built this for my own use after extracting it from a project. It originally, for me, was about keeping logs of a bunch of complex math stuff I was doing in a project and cross referencing concepts and what I'd tried/not tried etc. Once I extracted it, the "archaeology" features became key after talking with users. Now the Q&A interface from the local app and the archaeology are the most popular pieces, but it works very well to make better decisions when documenting things as it goes with the git history combed through already. It can also attach documents or other metadata to the nodes to track things like PRDs, notion write-ups, etc. Really anything the LLM can have access to.
