Zovo Flowchart

Steps and decisions into a laid-out flowchart with SVG, PDF and Mermaid exports.

Zovo Flowchart is a flowchart maker for ChatGPT and Claude. Describe a process as steps and decisions, or paste Mermaid flowchart text, and it lays the chart out in layers from top to bottom or left to right. It reorders each layer to reduce edge crossings, keeps boxes apart, wraps long text inside the boxes, routes arrows with right angles or straight lines, and places edge labels such as yes and no in open space. It also checks the process: node ids that do not exist, decisions with fewer than two branches, steps that are not reachable from the start, and loops. The interactive chart lets you pan, zoom and click a step to highlight the paths through it. Downloads: a vector SVG, a vector PDF (fit to the chart, Letter or A4) and Mermaid text.

“Turn this Mermaid text into a PDF flowchart: flowchart TD A[Login] --> B{Valid?} B -->|yes| C[Home] B -->|no| A”

Limitations

Up to 150 nodes and 300 edges per chart, 120 characters per box and 40 per edge label
No swimlanes, subgraphs, colours per node or manual positioning; Mermaid styling lines are skipped
The PDF uses standard fonts with Western European letters; other characters are simplified or shown as ? in the PDF only, with a note on the page
Charts are not saved; large charts get download links that expire after about one hour
