LetDraw

Product: LetDraw is a hand-drawn whiteboard for diagrams that explain how software works.
Code diagrams: It converts Mermaid and D2 code into editable shapes and can export diagrams back to Mermaid or D2.
Infrastructure inputs: It can generate diagrams from Docker Compose, Kubernetes, Terraform, Helm, Graphviz DOT, SQL DDL, OpenAPI, git log, EXPLAIN, Mermaid, and D2 inputs.
Diagram tools: The canvas includes editable tables and code blocks, mind maps, charts, math/LaTeX, smart connectors, and PNG, SVG, and PDF export.
AI: Users can generate diagrams from text, images, or voice, and ask AI to explain an existing diagram.
Integrations: LetDraw provides a REST API and MCP server, with documentation for connecting clients including Claude and Cursor.
API access: The API and MCP are available to Pro and Enterprise users; free and guest users cannot create tokens.
Privacy: The app works in the browser and offline, stores drawings locally by default, and makes cloud sync opt-in.
Encryption: Live collaboration and shared snapshots use browser-side AES-GCM end-to-end encryption, and requests use TLS with HSTS.
Compliance: LetDraw says it aligns with GDPR principles but is not formally SOC 2 or ISO 27001 certified.
Self-hosting: Enterprise includes a self-hosting option so data can stay on the customer’s own infrastructure.
Support: The support page says most requests receive a reply within one business day, with faster replies for Pro and Enterprise.
Audience: The getting-started guide names software developers, DevOps and platform teams, software architects, product and project managers, technical writers, students, and educators as typical users.
