Exact vs inclusive
Know what the count means.
Exact A ∩ B excludes identifiers also present in other sets. Inclusive A ∩ B includes them.

Compare sets. Inspect every intersection. Export figures for publication.
Paste or import gene, protein, metabolite, pathway or arbitrary identifier lists. Calculations are performed in your browser; dataset contents are not uploaded to VennScope.
Private by design
Your scientific lists stay in this browser session. Verified exports send only a cryptographic file hash and non-scientific export metadata to the verification service.

Live WYSIWYG editing: drag title, subtitle, set labels or intersection values directly on this figure. Font and size controls update the preview immediately. Arrow keys nudge 1 unit; Shift + arrow moves 10 units.
Diagram geometry is schematic. Numerical set and intersection values are exact for the parsed inputs. Font choices use only fonts installed on the user's device; no remote fonts are requested.
Venn vs UpSet
Use the right representation.
Venn is recommended for two or three sets. For larger comparisons, UpSet is usually clearer and does not force complex circle geometry.
Reproducible export
Verification without uploading data.
For verified exports, the final file is hashed locally. Only the hash and export metadata are registered; raw identifiers remain on your device.
