Frequently Asked Questions
What insights does Subreddit Overlap provide?
Audience overlap strength, adjacent communities, and shared-interest signals so you can expand research and distribution with confidence.
Is the analysis real time?
Yes. Overlap is computed from recent public participation at the time you run the tool.
How accurate are the AI insights?
Overlap is derived from public activity samples plus AI-assisted interpretation. It is a strong directional map, not a census of every subscriber.
Can I analyze any public subreddit?
Yes, as long as the communities are public and accessible. Private or empty communities will not produce useful overlap.
Can I export the results?
You can copy results from the page. Premium unlocks richer overlap intelligence and fuller reports.
What is included in Premium?
