OmniGen: make product and ad images with AI
OmniGen uses AI to create product photos and ad images. You describe what you want in Classic mode, or let it turn a product photo into an ad in Ad Engine mode.
বাংলায়: OmniGen হল একটি AI ইমেজ জেনারেটর যা আপনার বিবরণ অনুযায়ী পণ্যের ছবি এবং বিজ্ঞাপনের ছবি তৈরি করে। আপনি শুধু যা চান সেটা বলে দিন অথবা একটি পণ্যের ছবি আপলোড করুন এবং AI সেটাকে বিজ্ঞাপনে রূপান্তরিত করবে।
Where to find it: Sidebar › group Tools › OmniGen
What OmniGen is
OmniGen is an AI image generator inside Omnikyo. It needs a Gemini API key set up on your Settings (ask your tech person or an admin how to add it; there is no self-service field in the UI). Without the key, every generate request fails with "Gemini API key not configured. Please add it in Settings."
OmniGen has two modes. In Classic mode you write a prompt and pick a model, ratio and style. In Ad Engine mode you upload a product photo and let AI turn it into an ad with headline text.
Generated images are stored only in the browser while OmniGen is open. When you leave the page or close the browser, history is gone. Download each image you want to keep.
Generate an image in Classic mode
- Open Sidebar › Tools › OmniGen.
- Stay on the Classic tab.
- Type your prompt in Describe your imagination... ("a cozy home office with plants", "a yellow cotton shirt on a mannequin").
- Pick a Model: Gemini 2.5 Flash (fast, default), Gemini 3 Pro (high-fidelity), or Imagen 4 (photorealistic).
- Pick an Aspect Ratio: Square, Landscape, Portrait, Classic, or Poster.
- Pick a Style Preset: No Style (default), Photorealistic, Anime, Cyberpunk, Oil Painting, 3D Render, or Pencil Sketch. (A preset adds words to your prompt.)
- Click Generate Image.
- The image appears on the canvas. To try again, change the prompt or settings and click Generate Image again.
- Click Download to save the image as PNG.
- Each image appears in History on the left. Click a thumbnail to show it again.
Turn a product photo into an ad image
Ad Engine uses your product photo to suggest ad directions, then creates an ad with a headline.
- Open Sidebar › Tools › OmniGen.
- Click the Ad Engine tab.
- Click Upload Product and pick a photo of your product.
- Click Analyze & Ideate. OmniGen analyzes the photo and suggests 3 creative directions (titles and headlines).
- Pick one. Its visual prompt fills the composer.
- Optional: turn on Render Text if you want the suggested headline text added to the image itself.
- Optional: edit the prompt or write your own.
- Click Generate Ad Campaign.
- The ad image appears on the canvas.
- Click Download to save.
