问题

A CS student juggling five separate apps (timer, Anki, notes, YouTube, spreadsheet) felt overwhelmed and needed a unified, offline-first learning workspace.

结果

Cogniva replaces five separate study tools with a single offline-first PWA, providing Pomodoro timing, SM-2 flashcards, adaptive quizzes, AI assistance, analytics, and gamification. The student experiences a unified workflow, improved focus, and privacy‑first data handling.

The AI service first checks a curated preset knowledge base… If no preset matches, a dynamic template generator produces subject-aware, difficulty-scaled content. This means the app works completely offline without any API key.
