You watch it work.TaskTry once“Can my user actually do this?”Ad-hoc. You’re building a new flow and you want to know if it works for a real user, without scheduling a research session. Write the task, watch the agent try, read the screenshot of where it got stuck.PlaybookSave and replay“Did we break it?”Take any successful run and save it as a Playbook. Replay it deterministically on every build, from the dashboard. Pass or fail in seconds.ExperimentCompare two builds“Which design wins?”Run the same task against two builds of your app, side by side. See which one your users can complete and which one breaks, before the design debate goes to A/B testing in production.Task“Sign up with email and verify the welcome screen appears.”Agent exploringStep 1→Step 2→Step 3→Step 4The agent reports each step, what it saw, and what changed.What’s nextOn the way.In ProgressPhysical devicesRun tasks on a real iPhone attached to your Mac.NextAndroidSame Agent, against an Android emulator.NextCLI for CIReplay Playbooks from GitHub Actions, GitLab, or CircleCI.LaterHybrid appsReact Native and Flutter, treated the same as native iOS.Open betaStart free.Run tasks against a simulator on your Mac while we’re in open beta.
