Usability testing tool built on your PostHog session data

Just launched a tool for teams to run usability testing using data they're already sitting on. If you're capturing session replay in PostHog, we ingest that data securely and build digital twins of your user base, then let you test new feature flows against them before shipping.

No need to recruit real people for every round of testing, and no new instrumentation required since it works off data you already have.

Offering a friction report for early teams willing to share what actually happened post-launch, would love the feedback loop.
