Detailed Introduction
Smart Excalidraw is an AI-assisted visualization tool that converts natural language descriptions into structured, editable charts in Excalidraw format using large language models (LLMs). Generated diagrams are immediately editable on the canvas so users can refine layout and style manually, enabling a smooth pipeline from AI generation to human polishing. The project offers an online demo and a local deployment option; configuration requires an AI provider API key and stores settings locally in the browser to protect privacy.
Main Features
- AI-driven generation: LLMs interpret requirements and produce professional diagrams.
- Rich chart types: supports 20+ chart kinds including flowcharts, architecture diagrams, sequence diagrams, ER diagrams, and mind maps.
- Excalidraw compatibility: outputs native Excalidraw format for interactive editing.
- Ready-to-use: online demo and local run options with simple configuration.
Use Cases
Suitable for product prototyping, architecture design, technical documentation illustrations, and collaborative design reviews. Designers and engineers can describe needs in natural language to quickly obtain a structured diagram, then refine it on the Excalidraw canvas; it can also integrate into documentation pipelines and review workflows to speed visual output.
Technical Features
- Multi-provider support: compatible with OpenAI and Anthropic models; Claude Sonnet is recommended for best results.
- Smart connection algorithm: built-in connector optimization reduces line crossings and improves readability.
- Frontend storage: configuration and temporary data are saved client-side for privacy and lower server cost.
- Modern stack: built with Next.js, Excalidraw and TailwindCSS for easy development and extension.
