Comma-separated items. Matching is case-insensitive and trims whitespace. Example shown — replace with your own sets.
How it works
- Label your two sets and list their items, comma-separated.
- The tool compares both lists and finds items shared between them.
- The diagram redraws instantly, with unique items on each side and shared items in the overlap.
- Click Download PNG to save the diagram as an image.
FAQ
How do I list items for each set?
Type a comma-separated list into each set's items box, e.g. "HTML, CSS, JavaScript". The diagram automatically finds items that appear in both lists and places them in the overlap.
Is matching case-sensitive?
No — "JavaScript" and "javascript" are treated as the same item. Extra spaces around items are trimmed automatically too.
Can I make a three-circle Venn diagram?
This tool focuses on the most common two-set comparison for clarity and readability. For three or more sets, consider splitting the comparison into multiple two-set diagrams.
Can I rename the two sets?
Yes — edit the "Set A label" and "Set B label" fields; the circle titles and the shared/unique counts update immediately.
Is my data uploaded anywhere?
No. Everything — parsing, comparing, and drawing — runs locally in your browser using the Canvas API, including when you download the PNG.
