Briefcore (branded as EkSaar: Single Essence) is an AI-powered reading and knowledge-distillation platform designed to help users consume high-value books and insights efficiently. It bridges the gap between traditional reading and modern "on-the-go" learning by offering a multi-format experience (Audio, Text, and Interactive).
Below is a full summary of the app’s core functionality and features.
Overview: The "Single Essence" Philosophy
Briefcore (EkSaar) focuses on the "atomic essence" of knowledge. It is designed for students, creators, and professionals who want to stay informed without the time commitment of reading full-length books. The app distills productivity, psychology, philosophy, and self-growth titles into immersive experiences under 15 minutes.
Core Features & Functionality
1. Smart Summaries & AI Insights
AI-Powered Distillation: Uses advanced AI to generate smart summaries of bestsellers and classics, focusing on the most impactful takeaways.
Curated "Spark Highlights": Provides micro-takeaways that combine visuals, quotes, and concise text to ensure key ideas stick.
2. Advanced Audio-First Experience
Natural Narration: Every summary includes expressive audio narration, making it ideal for commuting or walking.
Audio Transcripts: Real-time text-to-speech synchronization allows you to switch between listening and reading seamlessly.
Player Controls: Features include playback speed adjustment, sleep timers, and smart chapter navigation.
3. Gamified & Interactive Learning
AI-Generated Flashcards: The app automatically creates interactive flashcards based on your highlights and the book’s content.

Offline Mode: Users can download summaries and audio for "flight-mode" learning or areas without internet access.
Curated Collections: Explore handpicked lists across categories like Digital Mindfulness, Innovation, and Growth Mindset.
Technical Architecture
The app is built using a modern, scalable stack designed for high performance and cross-platform accessibility:
Frontend: Flutter (for the mobile application) and Next.js (for the web interface/landing page).
Backend & Database: Firebase (handling authentication, real-time database syncing for notes/progress, and cloud storage).
Deployment: Vercel (hosting the Next.js web application).
AI Layer: Integrated AI models for generating summaries, insights, and flashcards.
