Free Venn Diagram Generator

For exact counts, enter your items in the fixed A, B and optional C lists below the input. The tool removes duplicates according to the chosen matching rule and calculates shared and exclusive regions. Export SVG or PNG and save the settings as JSON. The original AI input remains available for illustrated comparisons.

In research, a venn diagram visualizes shared and unique elements between groups — for example overlapping gene sets, common survey respondents, or features compared across methods. The intersection regions make it immediately clear what two or more sets have in common and what is exclusive to each. This venn diagram generator is built for that scientific framing, producing labeled two-set and three-set figures suitable for manuscripts, posters, and grant applications.

A two set venn diagram uses two overlapping circles with a single central intersection, ideal for direct A-versus-B comparisons. A 3 circle venn diagram uses three overlapping circles, creating seven distinct regions including three pairwise overlaps and one shared triple intersection at the center. SciFig generates both layouts with a schematic circle layout; exact counts are available separately in the two- and three-set counting tool.

Yes. Generate an unlabeled venn diagram with two or three empty overlapping circles, export it, and use it as a blank template that students or collaborators fill in by hand. The venn diagram maker keeps the circle proportions and intersection regions intact so the blank template stays geometrically accurate, making it a reliable worksheet or brainstorming starting point.

Set intersections appear as the overlapping regions where two or more circles cross. In a two-set venn diagram there is one central intersection; in a three-set diagram there are three pairwise intersections plus one triple overlap. SciFig labels each region precisely, so the shared elements between sets are easy to read. Accurate intersection geometry is essential for the diagram to communicate set relationships correctly.

SciFig works as a free venn diagram maker for everyday diagrams — describe your sets and generate a venn diagram online in seconds. Because it is a venn diagram generator built for scientific work, you can produce two-set, three-circle, and multi-set layouts with labeled overlapping circles, then refine and export them at publication resolution for papers, lectures, and presentations. It also works as a venn diagram maker free for quick drafts — generate with the venn diagram maker free, then refine and export at publication resolution. The exact mode below the input deduplicates items in two or three sets, counts each exclusive region and reports the union and intersections. Circle areas are schematic, not proportional to counts.
