Nice fit for debugging pipelines. A feature that would make this especially useful is a real tensor-diff mode: choose two compatible tensors or checkpoints and render absolute/relative error heatmaps plus percentile stats. Side-by-side comparison is helpful, but the diff view is usually where you can immediately see where two runs, preprocessing branches, or layers start diverging.

Neat Tool. I built something similar to visualize robotic trajectories stored in NPZ files using threejs in a client-side webapp. The quality of those auxiliary tools modern LLMs can just one-shot is truly mind-blowing. In earlier days I would have squandered weeks to that and would have ended up with something worse; I know enough js to get something done with threejs, but really i am trying to do robotics here.
Also incredibly impressed by your vectorizer tool. Will definitely consider this!
