Your Agent Can Now Build Tests and Send Them to Review

Chat interface showing a live test build card with progress, a preview link, and reviewer selection options

Ask your agent to build a test from a hypothesis, and you can now watch it happen. A live build card appears right in the chat, showing progress as the test comes together, with buttons to open or configure it while it’s still in motion. Once the build finishes, the same card shows the test’s name and a preview link, so you can see the variation the moment it’s ready.

  • Live build cards in chat, with progress and quick access to open or configure the test
  • Instant preview link and test name as soon as a build finishes
  • Send an idle or ready test to review without leaving the chat
  • Recommended reviewers suggested automatically, or hand-pick teammates and guests
  • Invite external reviewers by email, right from the same flow
  • Approval cards now name the exact hypothesis, test, or persona an action applies to

Hypotheses, right where you need them

Test tables now show a hypothesis popover with a link into the Explorer, so you can see the reasoning behind any test and jump straight to its origin without digging around. Hypotheses with attached images display more cleanly, the overall hypothesis UI is sharper, and the agent now writes tighter, more focused hypotheses even when you hand it a lot of context. You can also attach or remove triggers on tests that haven’t gone live yet, giving you more flexibility before launch.

Cleaner starts, sharper results

New agents now start with a sensible default goal and summary already in place, so setup begins further along. Screenshot captures dismiss cookie banners first, so you see the real page every time. Behind the scenes, test statistics are more accurate thanks to refined Bayesian analysis and attribution, and SDK configuration is now cryptographically signed for tighter security.
