A/B Simulate

A/B Simulate runs your A/B test in simulation, right in the chat. Ask Claude for a few versions of an ad headline, email subject line, e,ao; preheader, SMS, push notification, web headline, or social post, and A/B Simulate ranks them head to head with Neural 2.1, Jacquard's copy performance model, trained on billions of real marketing sends. You get the predicted winner, plus each variant's predicted lift in clicks over your current copy (opens, for push), before anyone on your list sees a thing.

Put your current or default copy first as the control. One simulation tests 2 to 20 variants and uses 1 credit, however many variants it has. Email subject lines, preheaders and push are calibrated. Ad, web and social headlines are provisional, and SMS returns the predicted order only. Results are predictions, not guarantees.

Use it to pick the line you send, to narrow a real A/B test down to your two strongest variants, or to get a read on sends that are too small, too last-minute or too one-off to test.

After the send, Claude can share how each variant did: total sent and clicks, plus opens and revenue if you have them. Sharing is free on every plan, and A/B Simulate shows the real result next to its prediction.

A/B Simulate never connects to your email platform, and never asks for subscriber lists, recipient addresses or individual events. It stores the variants you simulate, their predicted rank and lift, and any campaign totals you choose to share. It doesn't currently use your copy or results to train models.

The Free plan includes 10 credits a month. Paid plans start at $29 a month for 100 credits.
