TreeGPT (https://github.com/devnsko/treegpt) visualizes your ChatGPT conversations as a 3D graph, grouped by semantic meaning. The Java part handles the visualization of large graphs, so performance may be slower with bigger datasets.
GPTArchiveParse (https://github.com/devnsko/gptarchiveparse) is a Python tool for parsing ChatGPT conversation archives. It prepares the data for further analysis or visualization in TreeGPT.
