Quick Setup (< 1 hour)

You can use Eraser to generate technical diagrams and architecture maps from natural language prompts, code repositories, or existing documentation. It provides a visual canvas paired with an interactive chat assistant, letting you quickly iterate on layouts and system designs. Engineering teams can enforce design rules and templates, connect architecture maps directly to codebases, and drill down through multi-tier C4 models. It also includes an open-source MCP server, letting developers generate, update, and export diagrams directly inside AI coding assistants like Cursor and Claude.
