AI diagrams and technical design docs built from your code and systems
Generate architecture diagrams, flowcharts, sequence diagrams, and BPMN from a text prompt, code, Terraform, or an uploaded PDF, Word, Excel, PowerPoint, Draw.io, or Visio file.
Build interactive maps that sync with cloud accounts, repositories, and internal catalogs so the picture stays close to the real environment, with drill-down from org level to a single container.
Paste code or connect private and public Git repositories, Confluence, Notion, VS Code, and GitHub to keep diagrams grounded in actual implementation.
Run the agent toolkit in your own infrastructure under an MIT license and let MCP-compatible clients create, search, update, and export diagrams with OAuth or API tokens.

AI-powered water leak detection and smart water management for buildings
Real-time water insights with remote notifications and detailed consumption data, delivering leak prevention and control from wherever you are.
WRAS-approved control valves work with the monitoring platform to cut the water supply when a leak or abnormal flow pattern is detected.
A range of flow sensors and sub-meters for accurate, reliable measurement across different pipe sizes and fluid applications.
Cable that senses the presence of water along its length and can trigger automatic shut-off when paired with the control system.

#1
SpecialistAutomatically embeds visual diagrams directly inside text documents, though it lacks Eraser's specialized cloud architecture focus.
#2Provides extensive drag-and-drop shapes and templates for general diagrams, but weaker automated code-to-diagram capabilities than Eraser.
Combines team whiteboarding, documentation, and diagramming in one platform, but less tailored for automated codebase architecture.
