About Diagram Generator

Diagram Generator produces presentation-ready diagrams from a text prompt, and differs from most prompt-to-image tools in that the agent searches the web and grounds the facts before it renders anything, so a diagram of a real system or process is drawn from retrieved material rather than from the model's recollection. It covers sixteen or more diagram types — flowcharts, ER diagrams, sequence diagrams, mind maps and others — and lets you choose the output form at generation time and switch afterwards: an editable Mermaid definition when the diagram needs to live in a repository or a doc, or a rendered image up to 4K when it needs to go into a deck. A separate Logic Mode runs a reasoning pass over the structure before drawing, billed at one credit, which is aimed at diagrams where the arrangement matters more than the styling. Pricing is explicitly compute-based rather than seat-based: every plan buys credits, and resolution is what costs more, with 1K generation at one credit, 2K at three and 4K above that. The free Developer tier issues a one-time credit allowance so the output quality can be judged before any commitment, with a watermark on Pro-mode renders. The product is in public beta at version 2.4 and names the underlying image and reasoning models it uses on the page rather than describing them generically.
