Text2diagram (https://text2everything.vip/) generates visualizations from a statement.

Two generation modes: “Quick” (without account) for a diagram in one statement, without an account, and “Chat” (with account) which asks questions before generating.

Seven types of diagrams: flowchart, sequence, ERD, class, state, mind map, Gantt. Can be detected automatically from the instruction or chosen manually.

Export possible in SVG, PNG, and in Markdown or OPML.

LLM not specified.

Note: no history.

Free and account-free for Quick, with an account for Chat. Seems unlimited.
