Pxink is a free, 100% client-side utility built to optimize AI API spend. AI models like Claude and Gemini bill text tokens by density, but vision tokens strictly by image dimensions. Pxink leverages this quirk by wrapping massive text blocks or codebase logs into highly dense 1928px PNGs. The model's OCR reads the text perfectly, but your total token bill drops by roughly 60%. Requires zero setup, no accounts, and your data never leaves your browser.
