Eraser
What it is
Eraser creates AI-powered diagrams for technical teams from prompts, code, files, and private Git repositories. It supports flow charts, entity-relationship diagrams, cloud architecture diagrams, sequence diagrams, and BPMN diagrams. Users can refine generated diagrams with manual diagram-as-code editing or AI edits, and reference libraries can ground output in company building blocks. Teams can collaborate in real time, comment, tag, and invite unlimited free guests. Eraser lists GitHub, Notion, Confluence, and a VS Code extension, along with live diagram embeds and Git-powered updates. The free plan includes three files, three AI diagrams, and seven-day version history. Starter costs $15 per user per month when billed annually, or $20 monthly; private files begin with Starter. SAML SSO is available from Business. The diagram API is for paid users, while MCP operations depend on plan AI-credit limits. Eraser says it is SOC 2 Type 2 certified, conducts annual penetration testing, and does not train AI models on customer content.
