Description
Eraser is a design tool for engineers. It combines a diagram-as-code editor with an AI copilot that produces the first draft, so documenting a system stops being the thing everyone postpones.
What it makes
- Cloud architecture diagrams with icon sets for the major providers
- Sequence diagrams for request flows and protocols
- Entity relationship diagrams generated from a schema or a description
- Flowcharts and system diagrams for anything else
How the AI helps
Describe a system in prose and DiagramGPT produces a diagram you can edit. Paste a schema, a Terraform file, or application code and it infers the structure. Because everything is backed by a text syntax, diagrams live in version control and diff like code — the AI writes the syntax, and you refine it.
The rest of the product
Docs sit alongside diagrams, so design documents embed live diagrams rather than stale screenshots. A whiteboard mode handles the messy thinking stage, and there are integrations with GitHub, Confluence, and Notion.
Free for individuals, with paid plans for teams that need collaboration and private workspaces.
