Overview

About ChatFlowchart

ChatFlowchart builds diagrams from plain text and also runs the other direction, reading a screenshot, PDF or whiteboard photo and rebuilding it as an editable diagram. It covers flowcharts, UML sequence and class diagrams, ERDs, state machines and DFAs, Gantt and quadrant charts, Venn and Hasse diagrams and probability trees, and you refine the result by chatting with it. Output goes to PNG, SVG, PDF, Mermaid code, Draw.io or Excalidraw, a share link, or an animated flowchart video. A first chart needs no signup; the free tier caps monthly generations and watermarks PNG export. Pro is $15.90 a month or $99.90 a year, with a non-renewing $19.90 30-day pass and a $9.90 pack of 10 credits; the terms name a company registered in New Hampshire.

Editorial verdict

Pros & cons of ChatFlowchart

medium confidence

The screenshot-to-editable-diagram direction is the part worth showing up for — most text-to-diagram tools only go one way. Export into Mermaid, Draw.io and Excalidraw means you are not trapped if you stop paying, and the 30-day pass is an honest option for someone with one deck to build. The operator is a small New Hampshire-registered company with no team named on the site.

Pros

Reads screenshots and whiteboard photos back into editable diagrams
Around ten diagram families, including ERDs, UML, Gantt and probability trees
Exports to Mermaid, Draw.io and Excalidraw as well as PNG/SVG/PDF
A one-time 30-day pass and a credit pack exist alongside the subscription

Cons

No team or founders named; the terms give only a company name and a Portsmouth, New Hampshire address
The free tier watermarks PNG output and limits monthly generations
No public API found, so diagrams cannot be generated from your own scripts
