Eraser

Eraser generates production-ready technical diagrams from AI prompts, aimed at architecture and process teams, DevOps, technology consultants and software engineers. It provides DiagramGPT, a free diagram maker, a Git diagrammer, markdown notes, and integrations with GitHub, Notion, Confluence and VS Code, plus agent integrations and an MCP client catalogue.

Targeting engineers rather than general business users is what shapes the product, and the consequence is that diagrams are treated as artefacts that live beside code. A software architecture diagram is wrong within weeks of being drawn, and the only diagrams that stay accurate are the ones stored where the code is, reviewed when the code changes, and editable by the person making the change rather than by whoever owns the drawing tool.

The Git diagrammer follows that reasoning to its conclusion, generating diagrams from the repository itself rather than from someone's recollection of it.

Publishing an MCP client catalogue and agent integrations positions this for a workflow where the diagram is generated by an assistant reading the codebase, which is the natural end point of everything else the product does. A diagram nobody had to draw is the only kind that stays current, because the cost of regenerating it falls to nearly nothing.
