Olutil stands for Online Utilities — a growing suite of privacy-first, browser-native web tools. This sub-site offers craft and handmade calculators that run entirely in your browser: estimating yarn, knitting sizes, fabric, material ratios, bead counts, paper cutting, resin and clay, plus pricing and budgeting helpers. Every result is an approximate estimate, not a quote, and the numbers you enter never leave your device. 100% Local Processing
