Open the view
Open Path → Audience. The page picks your first three channels for an initial comparison; everything else lives in the toggle row above the chart. The page only renders when you have two or more channels in your workspace. With fewer than two, the page shows an empty state pointing you to create more channels.Toggle two to five channels
The toggle row shows every channel in your workspace. Click any chip to add or remove it from the comparison; selections update the Venn diagram, stats panel, and detail table immediately. You can select between two and five channels. Adding a sixth toggle is rejected; five is the maximum the Venn diagram renders cleanly. To compare more, swap channels in and out rather than stack them.Read the Venn diagram
The diagram shows one circle per selected channel. Each circle’s size scales with the channel’s total audience, so a glance tells you which channels are large and which are small. The intersections are the data:- Two-channel overlap. The lens shape where two circles meet shows the count of people who belong to both channels.
- Three-or-more overlap. For three or more circles, every region is meaningful. The center region (all circles) is the people in every selected channel; each two-way overlap is people in exactly that pair; each outer crescent is the people unique to that channel.
- No overlap. Circles render side by side without intersecting. That’s a real signal: those channels are reaching disjoint audiences.
What you can learn
Three concrete reads:- Concentration risk. If one circle dominates the diagram and barely overlaps with others, you’re depending heavily on a single channel. Losing it would cost you most of the audience it reaches.
- Redundancy. Two circles that overlap on 80% of their area are reaching mostly the same people. One of them is doing the work the other is also doing: a candidate to scale back or repurpose.
- Unique reach. A channel’s true value is the slice that doesn’t overlap with anything else. That outer crescent is your durable, channel-specific audience: the people you’d lose if you turned that channel off.
Edge cases
- Fewer than two channels selected. The chart needs at least two to compute an overlap. The page shows an empty state until you add a second.
- One channel is empty. A channel with zero attributed people renders as a missing circle in the diagram. The overlap regions still draw for the remaining channels.
- Same person on three channels. Counted in the all-three intersection region. The chart does not double-count them in the pairwise regions.
- Six or more channels. The toggle ignores the extra selection. Swap channels in and out to compare different combinations.
