Work on your A/B tests from the chat you already use. No terminal.

What is new

Apex now works inside ChatGPT and Claude. Connect it once, and the chat you already use can see your experiments, your live pages and your results.

Ask how a test is doing, have the chat draft the next one and read the result, without switching tools for every question. A test still goes live in Apex, and a person approves it.

What you can do with it

  • Ask: which tests are live, which are still collecting data and how each one is doing.
  • Live pages: look at the pages your tests run on, so the chat talks about your real page.
  • Build: describe a test in your own words, for example an easy A/B test on your home page, and the chat drafts it in Apex.
  • Launch: set the primary goal and approve the launch in Apex. Nothing goes live from the chat alone.
  • Read: the verdict, the lift and the confidence of a finished test, and what moved per device.

    How are my experiments running?

    Apex

    Home page test, live

    Two variants, still collecting data

    Apex answers from your account: which tests are live and how far each one is.

  • Build

    Create an easy A/B test on my home page.

    Apex

    DraftHome page test

    Set a primary goal, then approve the launch in Apex.

    The chat drafts the test in Apex. You set the goal and approve the launch.

  • Read

    How did my A/B test perform?

    Apex

    Verdict, lift and confidence

    What moved per device

    When a test is done, the chat sums up the result, just like the results page.

Good to know

The chat drafts a test; people check it and decide when it goes live in Apex.

Developers can do the same from the terminal with the Apex CLI.
