ThoughtDAG

Overview

ThoughtDAG is an open-source tool introduced via Show HN that replaces linear chat history with an editable directed acyclic graph (DAG). Developers can visualize and edit nodes to decide which parts of prior context are fed into the model, improving control, debuggability, and reproducibility. Developers should care because it offers fine-grained context management beyond standard chat logs, useful for complex agents and multi-branch workflows.
