Our verdict on LetDraw
LetDraw is a browser-based whiteboard and diagramming tool for engineers, DevOps teams, data teams, and other software-focused groups. Its AI can generate editable diagrams from text prompts, images, and voice, as well as from sources including Mermaid, D2, Docker Compose, Kubernetes, Terraform, SQL, and OpenAPI. Alongside diagramming, it provides comments, sharing links, workspace invitations, roles, live cursors, and collaborative editing.
The pricing structure starts with a Free plan that includes a full drawing canvas, PNG, SVG, and PDF export, Mermaid and D2 import, and 3 free AI prompts. The Pro plan is listed at $5 per month or $50 per year and adds unlimited documents and folders, real-time collaboration, version history, presentation mode, and more AI usage. Enterprise adds single sign-on, SCIM provisioning, automatic domain join, a self-hosting option, and priority support. This makes LetDraw particularly suited to teams seeking paid collaboration and AI features at a low monthly price, while organizations needing administrative controls have a separate tier.
Its platform fit is broad for technical workflows. LetDraw supports web access, a REST API, an MCP server, offline browser operation, and local processing. Diagrams can be exported as PNG, SVG, PDF, or WebM, while Mermaid and D2 provide import and export paths for diagram-oriented workflows. The product should appeal to software teams that want AI-assisted visual documentation without giving up source-based diagramming or collaboration. Teams seeking a general-purpose whiteboard without technical source support may find its engineering focus less relevant.
