Overview

Eraser is an AI co-pilot for technical design and documentation. It helps teams create diagrams, notes, and design docs from prompts and diagram-as-code, with the goal of producing accurate, consistent technical artifacts faster.

The product is aimed at engineering workflows that need structured visuals such as architecture diagrams, flow charts, sequence diagrams, ERDs, and cloud diagrams. The site also positions Eraser for collaboration, version history, exports, and integrations that fit into existing documentation and code workflows.

Features

AI diagram generation

Generate and edit diagrams from prompts, then refine them with manual diagram-as-code or AI edits.

Diagram-as-code workflow

Use diagram-as-code to keep diagrams legible and maintainable, with markdown-based notes alongside the canvas.

Infinite canvas and version history

Work on an infinite canvas with automatic saving and version history snapshots to reduce accidental loss of work.

Integrations and API

Connect Eraser to GitHub, Notion, Confluence, and VS Code, and use the API on paid plans for workflow automation.

Portable export options

Export work as PNG, SVG, PDF, or MD to move diagrams and notes into other tools.

Use cases

Architecture and system design
Create architecture diagrams for system design, infrastructure planning, or internal reviews using prompts and diagram-as-code.
Technical documentation
Draft technical notes, decision docs, and other documentation that stay linked to figures on the canvas.
Team collaboration and reviews
Build flow charts, sequence diagrams, ERDs, and cloud diagrams for day-to-day engineering communication.
Workflow integration
Keep diagrams in sync with code and docs by using GitHub, Notion, Confluence, or the VS Code extension.
Enterprise standardization
Use the enterprise offering to align AI output with reference architectures, deployment preferences, and internal governance needs.
