What is Eraser?

Eraser is a workspace for technical diagrams and design documents, built for software teams. Its headline feature is AI diagram generation: describe a system in plain English, paste code or a spec, and Eraser produces a cloud architecture diagram, sequence diagram, flowchart or entity relationship diagram that you can keep editing.

Diagrams are stored as diagram-as-code, so you can edit them by hand, with AI instructions or on a canvas. Eraserbot can draw diagrams from your codebase, and a Diagramming API lets you generate them from your own tools. Documents sit next to diagrams for design docs and RFCs, and Eraser integrates with GitHub, VS Code, Notion and Confluence. Its free DiagramGPT tool lets anyone try AI diagram generation without signing up.
