What is Eraser?
Eraser is a diagramming platform for technical teams. You can paste a text prompt, drop in Terraform code, or upload a design document, and its AI turns that input into a layouted diagram on an infinite canvas. The results can then be refined by hand or by continuing the conversation in AI chat. Teams can apply shared style presets, templates, and reference architectures so generated diagrams match their notation and real systems.
Beyond one-off diagrams, Eraser covers codebase diagrams that update from repositories, interactive drill-down maps from company-wide views down to single services, and guided explainers. It also offers AI documents for design docs, integrations with Confluence, Notion, VS Code, and GitHub, an API, and an MCP server so tools like Claude, Cursor, or ChatGPT can create and edit diagrams.
