Tensor Spy, a browser-based tensor inspector

Field notes

The interface accepts local tensor files through drag-and-drop, a picker, or clipboard paste, then exposes both visual slices and numerical inspection. Its stated workflow includes axis selection, dimension tiling, channel-order correction, reshaping, compatible-view comparison, and extraction from multi-tensor archives. The page specifically calls out anomaly counts for zeros, NaNs, and infinities, while keyboard shortcuts support moving through slices and tensors without relying entirely on pointer controls.
