Free AI banner generator.

Make web and social banners from your message and colors, in leaderboard, social square, and medium rectangle sizes. In Blu, the Brand Designer generates the same set from your catalog in Google Display and email header sizes, with brand tokens applied to every one.

How to use the AI banner generator

It takes three steps and every output renders on this page so you can copy or export it right away.

Enter the copy and colors

Type the offer and CTA, name your brand colors, and pick leaderboard, square, or medium rectangle.

Generate three banners

The AI banner generator returns three layout takes at the size you picked, ready to download as PNG.

Open it inside Intempt

This page makes the set once. In Blu, the Performance Marketer runs it as a standing play: the audience syncs to the ad platform, conversion is recorded first-party, and ROAS is graded against what customers actually paid.

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.

The audience syncs, conversion is recorded first-party, and every proposed spend change waits for you.
