Tyokiie: Offline Wiki+Timeline

Tyokiie is an offline-first Wikipedia reader and reference toolkit for exploring human knowledge without an account, sign-up, or internet connection. Search and read articles from an on-device language database with a clean reading experience, optional serif mode, collapsible sections, compact table of contents, and themes including Day, Sepia, Night, Nord, Chinese Ink, and Rice Paper.

Its flagship Parallel Timeline displays rulers, scientists, composers, regions, and major events side by side on a shared year axis. Switch between historical time from 3400 BC to today and a logarithmic cosmic view spanning the Big Bang, Earth’s formation, dinosaurs, and human history. Additional features include Wikimedia Commons portraits, cross-language Link Glosses, a scientific calculator, unit converter, and localization in 15 languages. Tyokiie is designed to be private, fast, and useful offline.
