85% of people say a brand's video has convinced them to buy a product or service. That figure comes from Wyzowl's 2026 video marketing survey.
The same survey found that 63% of video marketers have now used AI tools to create or edit video, up from 51% a year earlier.
The reason is simple. A filmed video ad needs a script, a shoot, an editor and days of back and forth. AI video ads need one prompt and a logo.
This guide shows how AI video ads work, how to write a prompt that gets a usable video, which sizes to use on Facebook and Instagram, and how to launch the ad with AiSensy.
What Are AI Video Ads?
AI video ads are short promotional videos that an AI tool creates from a text prompt and your brand assets.
You describe what you want. The tool builds the scenes, motion, layout and text overlays. You get several versions of the ad in one go, ready to review.
For businesses that sell on WhatsApp, the video does one more job. It runs as a Click-to-WhatsApp (CTWA) ad, so a tap on the ad opens a chat with your business.
Why Businesses Are Moving to AI Video Ads
Buyers prefer video. In Wyzowl's survey, 63% of people said a short video is their favourite way to learn about a product or service.
Marketers are following them. 41% of video marketers paid for video ads in the past year, up from 36% the year before.
AI makes it practical for a small team to keep up with that demand, because one person can now produce several ad versions in a single sitting.
