Tensor Spy
Inspect and visualize NumPy and PyTorch tensors directly in your browser
Visit tensorspy.com ↗What is Tensor Spy?
Tensor Spy is a free browser-based tool for inspecting and analyzing tensor files (.npy, .npz, .pt, .pth) without uploading data to servers. It's designed for machine learning engineers and researchers who need to validate data pipelines, debug model layers, and explore tensor contents during development.
The tool offers slicing, tiling, reshaping, and side-by-side comparison of tensors with automatic statistics including min/max, mean, standard deviation, and counts of anomalies like NaNs and infinities. Keyboard shortcuts and hover inspection enable detailed exploration, while high-contrast rendering highlights problematic values. The makers built it with ChatGPT 5.2 as an experiment in agentic coding.
