ThoughtDAG

ThoughtDAG replaces the linear chat transcript with an editable graph: conversations grow on an infinite canvas, and the wires between nodes determine exactly which context is sent to the LLM on the next request. You can branch, prune and merge threads, and preview the tokens the model will receive before asking, so an unrelated detour never pollutes a summary. The project is open source under the MIT license, local-first, and written in TypeScript.
