Olutil stands for Online Utilities — a growing suite of privacy-first, browser-native web tools. This sub-site offers language-learning helpers that run entirely in your browser: flashcards, vocabulary tests, an IPA reference, typing practice, word frequency, spelling and dictation, word roots, review planning, speaking self-assessment, GPA and score benchmarks. Pronunciation, word roots and score benchmarks are approximate references, not official, and whatever you type never leaves your device. 100% Local Processing
