Eraser
AI co-pilot for technical diagrams and markdown documentation.
What is Eraser?
Eraser, accessible via eraser.io (and sometimes searched as app.eraser.oi), is a technical design and documentation platform for engineering teams. It operates as an eraser ai co-pilot that helps developers create architecture diagrams, flowcharts, and sequence diagrams. Powered by diagramgpt (also referred to as diagram gpt), it functions as an ai diagram generator and flowchart maker ai. The platform combines a diagram-as-code canvas (which provides similar capabilities to a mermaid live editor or mermaid diagram tools) with a markdown note-taking editor, enabling teams to build technical designs alongside their documentation.
