AI-powered knowledge management
AI-powered knowledge management

1 / 2 Nexgraph is an AI-powered knowledge management platform that lets users transcribe and process audio, video, PDFs, and text documents into interactive mindgraphs — automatically extracting summaries, key points, and building semantic knowledge graphs that connect concepts across sources. Think of it as a second brain that organizes and links everything you feed it.
Users can add sources from local files, YouTube, Google Drive, or URLs. The app processes them with transcription and AI analysis to generate searchable summaries and structured concept hierarchies. Key features include: RAG-powered chat for querying your entire knowledge base in natural language, interactive graph visualization of relationships between concepts across sources, multi-language support, Firebase authentication with a premium tier, and sharing capabilities.
Built with Next.js, TypeScript, and Firestore. AI processing is handled client-side and server-side via OpenAI and DeepInfra APIs. The knowledge graph is rendered as an interactive force-directed visualization.
