Day Day Up - AI English Reading for Mandarin Speakers
Built for Mandarin speakers learning English - from age 6 to adult. Make daily progress, one fox at a time.
[Three Core Innovations]
* AI-Tailored Articles
No grinding worksheets. AI generates a fresh article every day from 16 topic areas, matched to your CEFR level and interests - kids get science, sports, history and stories; adults get business, health, current affairs, personal finance, arts and psychology. Tap Easier or Harder inside any article and AI rewrites the same story at a different Lexile level in seconds.
* 6-Color Polysemy Magic (Exclusive)
"Run" has six meanings in one article? AI auto-classifies every occurrence and tags each sense with a unique color: yellow for "to run", purple for "to flow", orange for "to operate", and so on. See multi-sense words at a glance, no more flipping dictionaries.
* 4D Pronunciation Scoring
Powered by Microsoft Azure Speech (same engine used by Duolingo): four-dimensional scoring on accuracy, fluency, completeness, prosody. Every mispronunciation gets targeted feedback in the user's chosen UI language.
