How do I make a banner with AI?

Type the offer and CTA, name your brand colors, pick a size, and click generate. You get three banner layouts to download.

Which sizes does it make?

Three: a 728x90 web leaderboard, a 1080x1080 social square, and a 300x250 medium rectangle. For a print or event piece instead, use the AI flyer generator.

Can it make a YouTube banner?

Not at YouTube channel art size. It makes the three sizes above, so for a channel banner you'd need to resize or rebuild the layout to YouTube's spec.

What should I put in the ad copy box?

The offer, the CTA, and one supporting detail. For example: "Summer Sale - 30% off everything, shop now, free shipping over $50".

Does it keep my brand colors?

Yes. The colors you enter carry through all three variants in a run, so the set looks like one campaign.

Can I save the banners?

Download from the toolbar above the result, and nothing is stored unless you sign up for Intempt.

What happens after I sign up for Intempt?

The Performance Marketer syncs the audience, the Brand Designer produces the creative per angle, and platform ROAS gets graded against first-party revenue every morning. It reads and it drafts, it does not reach into your ad account. You stay the strategy layer and publish the change yourself.

Teams love it

They stopped stitching tools andhired one system.

Acquisition and retention are one connected motion. Personalizing the path before signup only pays off when the same system carries the user through onboarding afterward.

Anonymous traffic was not turning into registered users, and acquisition and retention were run as two separate problems. We ran Experiences on the anonymous visitor flow to put the right content and CTAs in front of each visitor, then handed new signups to automated Journeys for onboarding and deeper engagement.

Judge experiments on revenue per visitor instead of conversion rate. A variant can win on conversions and still lose on revenue, and repeat buying only shows up when the whole journey is in one view.

High-intent shoppers browsed a large, specialized outdoor catalog, and browsing, product interest and purchase history sat in different places. We unified them into one customer view, then ran real-time personalization, intent-based segmentation and timely follow-ups on top of it, judging experiments on revenue per visitor.

Build the pipeline on observed signals. When follow-ups trigger on intent, the team spends its time on the users who are genuinely engaging.

Static lead lists and timeline-based follow-ups were hiding who was actually engaging. We ran a signal-led outbound pipeline where follow-ups fire on real behavior: outbound replies, onboarding progress and product usage.
