NoteWave is an AI-powered "Second Brain" and immersive research ecosystem. It transforms static PDF documents into dynamic knowledge graphs, interactive research studios, and voice-enabled learning environments.
Built with Next.js 16 (Turbopack), NoteWave utilizes high-integrity LLM orchestration, vector search, and real-time audio processing to redefine how we interact with documents.
It is strongly recommended to run this application locally.
The publicly deployed version is intended purely as a portfolio demo. Because it relies on free-tier API keys (Groq & ElevenLabs), it may be rate-limited, become unavailable, or run out of credits without notice. Running locally gives you full control and complete data privacy.
NoteWave is organized into specialized "Studios," each designed for a specific cognitive task:
-
RAG-Powered Chat
Professional document analysis with semantic source citing using Pinecone and Groq (Llama 3.3 70B). -
Podcast Studio
Generates an engaging audio deep-dive conversation between AI hosts. Supports MP3 downloads and real-time script tracking. -
Flashcard Studio
AI-driven concept extraction with a 3D flip UI and "Creator Mode" for manual additions. -
Knowledge Graph
A 3D Force-Directed Graph that visualizes relationships between concepts in your research. -
Agentic Debate
Multi-persona research environment where Dr. Skeptic, The Weaver, and Veritas debate the core thesis of your documents. -
Verified Vault
Integrity auditor that scans for bias, logical fallacies, and "hallucination" scores. -
Quiz Studio
Adaptive learning module that generates custom assessments and detailed mastery reports. -
Voice Immersion
Hands-free mode using Deepgram Nova-2 (speech-to-text) and OpenAI TTS-1 (neural voice replies).
-
Adaptive Settings Studio
Bio-Adaptive Profile that tracks cognitive load and suggests personalized learning styles (Kinesthetic, Visual, etc.). -
Focus Mode
UI transformation that dims distractions and simplifies the workspace for deep work. -
Command Orchestration
Global/command palette with full keyboard navigation for instant studio switching. -
Local Persistence
Session settings and document metadata synced tolocalStoragefor privacy-first continuity.
Centered chat interface with resizable sidebars for sources and studios.
Clean directory guiding users to specialized AI tools.
