Eraser
AI diagramming and docs for software architecture and technical systems
About Eraser
## Intro Eraser is a diagramming and documentation tool for technical teams. You can draw on a canvas, write diagrams as code, or describe a system and let AI lay out the diagram for you. It covers architecture, data flow, sequence, ERD, network and flowchart diagrams, plus design docs. It is aimed at engineers and architects, but it has become useful for AI-assisted builders too: a clear diagram of your app helps you explain it to clients, teammates and the AI tools writing your code. ## Key features - **AI diagram generation.** Create diagrams from a text prompt, Terraform, a design doc or an uploaded file such as a PDF, Word doc, Visio file or image, then refine on the canvas or through AI chat. - **Diagram-as-code.** Write diagrams in code so they can be versioned and edited like any other text, with 3,000+ tech icons built in. - **Codebase diagrams.** Connect a GitHub repo and Eraserbot creates diagrams of your codebase that update themselves as the code changes. - **MCP server.** Lets Claude, Cursor or ChatGPT create, search, update and export Eraser diagrams, which suits builders already working with AI coding tools. It also integrates with Notion, Confluence and VS Code, and exports to PDF, PNG, SVG and Markdown. ## Best for Eraser suits technical founders documenting how their app fits together, developers who want architecture diagrams kept in sync with code, and agencies handing over technical documentation to clients. Larger teams can use style presets and naming rules to keep diagrams consistent. Non-technical founders sketching simple flows will find Whimsical easier and cheaper. ## Pricing summary The free plan allows 3 files and 3 AI credits. Business is $45 per member a month billed annually, or $60 monthly, with 100 AI credits. Business Plus is $42 per member annually with a 10-seat minimum. Enterprise is custom. Education users and nonprofits can ask for a discount. ## Quick verdict Eraser is one of the best tools for turning a codebase or a rough description into a clean technical diagram, and the MCP server is a real plus for AI-assisted builders. The catch is price: the free plan is a short trial, and Business costs far more per seat than general diagram tools. For a solo technical founder, try the free Git Diagrammer tool first to see how Eraser reads your codebase. Teams documenting complex systems will get the most value, especially if diagrams currently go stale the week after they are drawn.
