What is Eraser?

Eraser is an AI diagramming and documentation platform for architecture and process teams. It turns text prompts, code, and uploaded files into technical diagrams, including architecture maps, network diagrams, flowcharts, and entity relationship diagrams. Users can supply Terraform, reference Git repositories, or upload design documents to give the AI context about their systems.

Generated diagrams open on an editable canvas, where users can make manual changes or request revisions through AI chat. Teams can define notation rules, styles, templates, and reference architectures to keep diagrams consistent. Markdown notes, real-time collaboration, comments, and exports to PDF, PNG, SVG, and Markdown support shared technical documentation.

Eraser also supports interactive system maps with drill-down views and connections to code, cloud accounts, and internal catalogs. A diagramming API and MCP server let software agents create, find, update, and export diagrams. The free plan includes three files and three AI credits; paid plans add higher allowances, private files, and connected data sources.
