About This Template

InstaGraph is an open-source knowledge graph generator inspired by Yohei Nakajima's Instagraph.ai that transforms unstructured text into interactive visual knowledge graphs using AI. Built with a Next.js frontend for the web interface, FastAPI backend for AI processing, React Flow for graph visualization, Tailwind CSS and Headless UI for styling, and OpenAI API for intelligent graph generation, this full-stack application demonstrates how to build AI-powered data visualization tools that make complex information easier to understand. The platform features automatic knowledge graph generation from user-provided text, interactive graph visualization with zoom, pan, and node manipulation, streaming and server-sent event endpoints for real-time updates, clean web interface for easy text input and graph viewing, and seamless integration between modern frontend and Python backend technologies. Users simply navigate to the application, input their text content, click submit, and watch as the AI analyzes relationships and concepts to generate a visual knowledge graph showing connections between ideas, entities, and topics. This visualization approach is invaluable for students and researchers organizing study materials and research notes, content creators mapping out article structures and topic relationships, product managers visualizing feature dependencies and user flows, educators creating visual learning aids from textual content, and anyone trying to understand complex information through visual connections. The project showcases how to architect full-stack AI applications with separate frontend and backend concerns, implement OpenAI integration for natural language understanding, build interactive data visualizations with React Flow, handle streaming responses for real-time feedback, and create intuitive interfaces for AI-powered tools. InstaGraph makes knowledge more accessible by transforming dense text into clear, visual representations of how concepts connect.

Note Gen

Note Gen is an AI-powered Markdown note-taking application that combines traditional writing with advanced features like automatic note generation, semantic search, and retrieval-augmented generation (RAG) to enhance knowledge management. Built with Next.js 14, TypeScript, and shadcn/ui, it enables users to write in Markdown, organize with tags and folders, and leverage OpenAI's GPT models for intelligent content creation. The application uses vector embeddings for semantic search that finds notes by meaning rather than keywords, RAG technology that references existing notes when generating new content, and auto-completion for writing assistance. With a clean interface featuring real-time Markdown preview, syntax highlighting, and keyboard shortcuts, Note Gen transforms note-taking into an active knowledge management system. Perfect for students, writers, developers, and professionals, it helps brainstorm ideas, discover connections between notes, and synthesize information across your knowledge base.
