Cohorts are PostHog's way of letting you easily create a list of users who have something in common.
You can use the cohorts to:
View a list of users who all did the same action or have the same property. A few examples of how you might use this are:
- "Which users used the app today"
- "Which users work at the same company"
- "Who used the app once but never came back"
Segment other statistics. For example, to view user paths or action trends. This let's you understand things like:
- "Are people at company X using the app much?"
- "Is the number of Daily Active Users going up or down over time?"
