Correlation Heatmap is a free online tool that computes the asset-by-asset Pearson correlation matrix of your data and draws it as a heatmap. Paste prices from a spreadsheet, and see at a glance which assets actually diversify each other — everything runs locally, nothing is uploaded.

Correlations are computed on log returns (or your pasted returns directly) with pairwise-complete observations. A correlation of 1 means lockstep, −1 means perfect opposition, 0 means no linear relationship — and correlation is not causation. Your data never leaves this browser.
