Cogniva — AI-Powered Adaptive Learning Workspace Built for a Friend

Description and use

Cogniva consolidates five study tools into a single offline-first PWA, offering Pomodoro timing, SM‑2 flashcards, adaptive quizzes, AI assistance, analytics, and gamification, while preserving privacy and offline functionality.

Problem

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

Outcome

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.

Workflow

• 1. Install the app locally or use the live deployed demo.
• 2. Log in as the demo user "Alex Morgan" or create a new profile.
• 3. Use the dashboard to view KPIs, streak alerts, and activity heatmap.
• 4. Start a Pomodoro session via /app/focus, tag the session, and receive XP rewards.
• 5. Review flashcards with SM-2 spaced repetition at /app/flashcards.
• 6. Take adaptive quizzes at /app/quizzes, receive explanations and accuracy tracking.
• 7. View learning analytics at /app/analytics for weekly study hours and accuracy trends.
• 8. Access the AI co‑pilot to explain concepts, diagnose mistakes, generate study plans, or create flashcards/quizzes with one click.
• 9. Manage tasks and schedule in the planner at /app/planner.
• 10. Earn XP, levels, streaks, and badges via gamification at /app/achievements.

Evidence

Cogniva replaces all of them with a single cohesive workspace.

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.
