What is Eraser?

Eraser creates production-ready diagrams in seconds using AI. Describe a system in plain language, point it at a codebase, or drop in a file you already have, and Eraser returns an editable technical diagram – architecture, sequence, flow chart, ERD or BPMN.

Create diagrams with AI

Generate from a prompt, an existing image, or a file such as Terraform or a database schema. Refine the result by chatting with it, or edit it directly in the visual editor.

Layout is handled for you, so diagrams come back clean rather than needing to be tidied up by hand. Everything is also diagram-as-code, which means anything AI produces can be read, diffed and edited as text.

Consistent diagrams every time

Generic output is the usual problem with AI diagramming. Templates, references, rules and custom styles ground generation in your own architecture and conventions, so results stay on-brand and match how your systems actually work.

Work where your systems live

Connect a Git repository to generate codebase diagrams, and let Eraserbot keep them current as the code changes. Diagrams sit alongside markdown documents in the same file.

Agent-ready

The MCP server and agent integrations give coding agents full read and write access to diagrams, so a diagram stays in step with the work an agent is already doing.
