## What is Pictwave?

Pictwave turns uploaded artwork into compact frequency signatures and animated waves. Compare low, mid, and high frequency traits, contrast, line rhythm, and similarity across works. The free MVP supports Sign in with Apple, Google sign-in, and up to 10 saved works. Images are analyzed in the browser; Pictwave stores compressed previews and feature data.
