Engineers who write design docs get diagrams from text or code on a usable free plan, though three files won't last long.

Kenning's take

What it does

Eraser turns a written description or pasted code into technical diagrams such as cloud architecture and database charts on an infinite canvas, then edits them with AI. It also drafts design documents and can keep codebase diagrams up to date through a bot. A diagramming API and an MCP server let other apps and coding agents use it.

• AI diagrams from text or code
• Diagram-as-code
• AI-drafted technical design documents
• GitHub, Notion, Confluence and VS Code integrations
• Diagramming API and MCP server

Who it suits. Software engineers, architects and DevOps teams who write technical designs.
