About

Ottisk

Read full description

Learning sticks when you need to know what happens next. Ottisk blends binge-worthy original novels, audiobooks and practice across Russian, Spanish, German and English. Love the energy of light novels, the atmosphere of manhwa or the style of anime? Pick an original fantasy, romance, mystery or progression novel – and stay inside the story instead of switching to a textbook. STAY IN THE STORY Meet an unfamiliar word? Tap it for a translation based on its context, then save it with the original sentence. Need the whole passage? Translate the paragraph without leaving the reader. LISTEN FROM THE EXACT PARAGRAPH See at a glance which chapters are narrated. Start audio from any voiced paragraph, then keep listening across chapters in the background. Change the speed, use Lock Screen controls or set a sleep timer. TURN STORY MOMENTS INTO MEMORY Saved words become review cards together with their original sentence. Smart spaced repetition brings each card back at the right time: less drilling, more story. READ YOUR WAY • keep opened chapters available offline; • adjust fonts, spacing, margins, brightness and paragraph focus; • choose light, sepia, dark or AMOLED themes; • use the complete interface in English, Spanish, German or Russian; • start without creating an account. Choose a story, open chapter one, and let curiosity keep you learning.
