What it does
Built for testing real flows
The same synthetic feedback engine you know, reachable from any page.
Element-precise capture
Drag a region, grab the whole page, or hover to pick a single element devtools-style — the screenshot rides along with the session.
Live results in the popup
Watch the persona's run advance step by step and see whether the goal was met, streamed straight back to the toolbar.
Secure login handoff
Behind a sign-in? Hand off to a secure live-view capture so the crowd tests the authenticated page — powered by Airtop.
Workspace-aware
Switch workspaces from the popup; prototypes, personas, and sessions all stay scoped to the right team.
