About

Eraser is an AI-powered diagramming and technical documentation tool aimed at engineering teams that need to produce architecture diagrams, design docs, and system maps quickly. Instead of dragging shapes around a canvas, users describe what they need in text, paste code such as Terraform, or upload files, and Eraser generates a laid-out diagram that can then be refined manually or through AI chat.

The product, made by Eraser Labs, combines a diagram-as-code approach with an AI assistant, a visual canvas editor, and an open-source MCP (Model Context Protocol) toolkit that lets agents in tools like Claude, Cursor, or ChatGPT create, update, and export diagrams. It also supports standardization through team-defined rules, styles, and templates, so generated diagrams stay consistent with an organization's notation and brand. The company states it serves more than 5,000 customers and targets software engineers, enterprise architects, DevOps teams, and technology consultants.

Key Features

AI diagram generation: Users can generate diagrams from text prompts, code (including Terraform and Git repositories), or uploaded files such as PDF, Word, Excel, PowerPoint, Draw.io, and Visio documents, plus images in PNG, JPEG, or WebP.
Visual editor and AI chat: Every AI-generated result lands on a full canvas, where users can edit by hand or keep iterating through a chat interface.
Rules, styles, and templates: Teams can define naming and notation rules, colors, layout conventions, reference architectures, and patterns so that AI output matches their real systems and stays on-brand.
Agent toolkit with MCP server: Eraser provides full diagram CRUD (create, read, update, export) for agents in Claude, Cursor, or ChatGPT, with OAuth and API token authentication over HTTP and stdio transports.
Open-source, MIT-licensed components: The agent toolkit can be self-hosted, its source is available on GitHub for inspection and auditing, and an open SDK supports building custom tools.
System and organization mapping: Microsite-style maps support interactive drill-downs (C4 context, containers, components), syncing from code, cloud accounts, and internal catalogs, and guided interactive explainers.
Security and deployment options: Eraser is SOC 2 Type 2 certified, undergoes annual penetration testing, supports SAML SSO with providers such as Microsoft Entra and Okta, and offers multi-tenant, single-tenant, or self-hosted deployment.

Who It's For

Eraser is built for software engineers, enterprise architects, DevOps teams, and technology consultants who need to produce architecture diagrams, design docs, documentation, data flow diagrams, wireframes, and brainstorming visuals. It suits teams that want to standardize notation across many diagrams, keep diagrams grounded in their actual codebase and infrastructure, or let AI agents maintain documentation automatically. Organizations with strict security requirements — such as those needing SAML SSO, SOC 2 certification, or self-hosting — are also addressed through the Business and Enterprise plans.
