Eraser

Eraser uses AI to create editable technical diagrams and documentation from prompts, code, files, and Git repositories.

Eraser

Eraser helps engineering and product teams create architecture diagrams, flowcharts, sequence diagrams, entity relationship diagrams, and technical documents. Users can generate diagrams from natural-language prompts, codebases, images, Terraform, database schemas, and other files.

Diagrams remain editable through AI prompts, diagram-as-code, or the visual editor. Eraser also supports Git integrations, MCP and API access, real-time collaboration, and exports. The free plan limits files and AI credits; API tokens require a paid plan.
