A focused AI product is not scored like a free technical editor or a workshop suite.
Workshops
Miro

Free
draw.io
Free core editor with technical shapes, desktop, and self-hosting.
Docs-as-code
Mermaid
Text diagrams for repositories, PRs, and documentation pipelines.
Enterprise
Lucidchart

Match the tool to the workflow.
Most disappointing purchases happen when a broad suite is chosen for a narrow job, or a free canvas is forced into enterprise governance.
