What is an AI ad generator?
An AI ad generator turns a written brief into finished ad creative. Instead of briefing a designer or a video crew, you describe the product, the scene, and the format you want, and generative models produce the image or video. The best ones also understand ad-specific needs: aspect ratios for feed and Stories, room for a headline, product fidelity, and the creator-style realism that performs on Meta and TikTok.
AdStellar goes a step further than a standalone generator. The same composer you see above sits inside a full ad platform, so a generation is not a file to download and re-upload somewhere else. It becomes a creative in Canvas that you can pair with copy and audiences, test as hundreds of variations, launch to Meta, and measure with creative analytics that tell you what to make next.
Because every model is available on every plan, you can route each job to the model that suits it: GPT Image 2.5 Flare for phone-camera UGC realism, Nano Banana Pro for accurate on-image text, Imagen 4 for cinematic product shots, and Kling, MiniMax, or Seedance for video.
