Zeyls is a Swedish software company building focused, practical apps in two areas: language learning and B2B sales tools.
Learn a language that actually sticks.
Yadger is our language-learning app, built around real reading, vocabulary, grammar, and pronunciation practice — with AI-powered coaching to guide you along the way. It started with Farsi/Persian and now supports 26 languages.
Whether you're learning to reconnect with your roots, prepare for travel, or simply love languages, Yadger is designed to make consistent progress feel natural.
