About nocturne_memory

About thoughtdag
ThoughtDAG is an MIT licensed TypeScript application that turns LLM conversations into an editable thought graph on an infinite canvas, where each exchange becomes a node and the wires between nodes, rather than the whole transcript, decide what the model sees next; it is built for people who branch into side questions and want to keep the useful paths.
