Use Pi as a terminal-based coding agent that can be customized by its users.
Eraser
Eraser generates technical diagrams from text, code, or files for architecture and process documentation.
About Eraser
Eraser is a web tool for creating technical diagrams — such as architecture and business process diagrams — from text prompts, code, or uploaded files. An AI result is placed on a full canvas where it can be refined by hand or through chat, and output can be made consistent using AI presets, team style presets, templates, naming and notation rules, policies, and reference architectures.
Key features
- Generates diagrams from text prompts, code such as Terraform, and uploaded design docs
- Accepts image uploads (PNG, JPEG, WebP) and files (PDF, Word, Excel, PowerPoint, Draw.io, Visio)
- Full canvas visual editor plus AI chat for refining generated diagrams
- Team style presets, templates, and rules for consistent notation and layout
- MCP server supports diagram create, search, update, and export from Claude, Cursor, or ChatGPT
- Interactive microsites with drill-downs across system maps, syncing from code, cloud accounts, and catalogs
Best for: Architecture, platform, and process teams that need to document systems and workflows quickly from text, code, or existing files.
Good for
- Multiple input types, including prompts, code, git repositories, uploaded images, and documents
- Templates, rules, reference architectures, and knowledge can ground AI output in how a team's systems work
- Enterprise options include SOC 2 Type 2 certification, annual penetration testing, SAML SSO, and multi-tenant, single-tenant, or self-hosted deployment
Watch out for
- Pricing is not stated on the homepage
- MCP-based diagram creation runs through third-party assistants such as Claude, Cursor, or ChatGPT
- The open-source, MIT-licensed, self-hostable component is the agent toolkit, not the full product
