features

The creative loop
that learns and improves.

01

Brief to creative in 60 seconds

Type your campaign goal. Creative Engine generates copy, headlines, CTAs, and visual briefs — in your brand voice, for your target audience, across every channel format.

02

Brand voice enforcement

Upload your brand guidelines once. Every creative generated by Plexrio — forever — matches your voice, tone, vocabulary, and visual identity automatically.

03

Automatic A/B testing

Creative Engine launches multiple variants simultaneously and runs statistical significance testing in the background. You see the results — not the math.

04

Creative fatigue detection

Creative Engine monitors impression frequency and CTR decay. When a creative is burning out — before performance visibly drops — it flags the fatigue and queues replacements.

05

Winner auto-promotion

When a variant reaches statistical significance, Creative Engine promotes it automatically — increasing its budget allocation and pausing underperformers. No manual A/B management.

06

Winning pattern extraction

Every winning creative teaches the system. Creative Engine extracts the patterns — hooks, CTAs, emotional triggers, formats — and uses them to brief the next generation.

the fatigue problem

Your best ad stops working after 4 days.

On Meta, the average winning creative shows fatigue signals within 4.2 days of launch at scale. By day 7, CTR has dropped 40%. By day 14, you are paying 2x the CPM for 60% of the results. Most teams catch this at the weekly review — after thousands of dollars in degraded performance. Creative Engine detects the signal on day 3 and queues a replacement before the drop is visible in ROAS.

faq

Common questions.

What formats does Creative Engine generate?

Meta ad copy (primary text, headline, description), Google ad copy (headlines, descriptions), LinkedIn ad copy, email subject lines and body, landing page headlines, and visual briefs for your design team or AI image tools.

How does brand voice training work?

You upload your brand guidelines, existing ad copy, and any approved content. Creative Engine extracts your voice patterns — vocabulary, sentence structure, tone, messaging hierarchy — and applies them to every generation.

Does Creative Engine generate images?

Creative Engine generates visual briefs and copy. For image generation, it integrates with tools like Midjourney and DALL-E. Full native image generation is on the roadmap.

How many variants does it generate per campaign?

Configurable — default is 3-5 variants per ad set. For high-spend campaigns, we recommend 5-8 variants to maximize learning velocity. Creative Engine manages the testing automatically regardless of variant count.

What is creative fatigue and when does it happen?

Creative fatigue occurs when the same audience has seen your ad too many times — CTR drops, costs rise. It typically starts around 10,000-15,000 impressions per unique user. Creative Engine detects the signal before the drop becomes visible in ROAS.
