A free AI ad generator that starts from one line of brief
Write what the ad should show, pick the placement ratio, and get a finished creative back. No layers, no timeline, no template gallery to dig through before you see anything.
Generate an ad from a brief
Step one renders your ad still from the prompt, and step two shows a motion preview of how that still would move.
Describe your product in the prompt — colour, packaging, label — and your AI actor will hold it.
The gap between brief and creative
Every performance team has the same bottleneck, and it is not ideas. It is the distance between writing a brief and looking at something. A concept gets typed into a doc on Monday, enters a design queue, comes back Thursday in the wrong ratio, and by the time it is fixed the buyer has moved budget elsewhere. An ai ad generator removes the queue entirely: the brief and the creative are the same action. You type the concept into the prompt box and the render appears, which means an idea gets judged on the day it is had rather than the week after.
That speed changes what a test set looks like. When a creative costs a sentence, you stop defending your favourite concept and start shipping six. The ones that die, die on impressions instead of in a review meeting, and the survivors are the ones the audience picked rather than the ones that survived internal politics.
What this generator does well
Brief in, creative out
There is no intermediate artefact. You do not build a storyboard, pick a template or arrange assets on a canvas — you describe the finished ad and the generator renders it. The prompt box is the whole interface, which is why a first result takes under a minute.
Six ratios, one brief
9:16, 4:5, 1:1, 16:9, 4:3 and 3:4 are all available from the same prompt, so a concept that works vertically can be re-rendered for the feed or for pre-roll without redoing the composition by hand in an editor.
Nothing between you and the tool
It is free and anonymous. Nothing to set up, no card, no seat to provision for the intern who just needs one static by five o’clock. A Cloudflare Turnstile check keeps bots out and then the generator runs.
Three steps to a shippable creative
The whole loop is short enough to run between two meetings.
Describe the finished ad
Write it as if you were describing a frame to a photographer: who is in it, what they hold, where they are, how it is lit and how tightly it is framed. Concrete nouns beat adjectives every time.
Match the ratio to the placement
Choose the shape the ad will actually run in before you render, not after. Rendering natively in 4:5 for the Meta feed avoids the cropped-head problem that kills half of repurposed creatives.
Preview the motion and iterate
Run the motion preview to see whether the frame holds up moving, then adjust the brief. Most concepts need one revision on framing and one on wardrobe before they are ready.
Common questions
A photoreal ad still in the ratio you chose, showing an AI actor with your product in the setting you described. After that you can play a motion preview of the same image to judge how it would move as a video ad before you commit to a full cut.
No. There is no canvas, no layer panel and no export dialog to learn. The skill that matters is writing a clear brief — the same skill you already use when handing a concept to a designer, just applied directly to the prompt box.
Run as many prompts as you need. The tool is free and anonymous, with a Turnstile check between you and each generation, so building a test set of six variants is a matter of time rather than budget approval.
Describe it in words — shape, colour, material, label style, how it is being held. The generator renders from the description, so the more precisely you write the packaging, the closer the rendered product sits to the real thing on your shelf.
