Your article needs an image that explains its idea.
OGAD (Off Grid AI Desktop) lets you generate a blog illustration locally on your computer. Describe the scene, choose a visual treatment and refine a draft without using a cloud image-generation service. Download the app and model first; generation can then work without internet.

Turn the article’s idea into a visible scene
Start with what the reader should understand. An article about focused work might use a quiet desk with one open notebook. A guide to local AI could show a phone and computer in a home workspace. A gardening article could show a simple raised bed and a few tools.
Use a scene the image model can draw. Exact software interfaces, technical diagrams and charts need separate checks and often work better in tools where you control every label and connection.
For a post about focused work:
An editorial illustration of a quiet desk with one open notebook and a pencil, warm morning light, muted green and cream palette, simple shapes, generous empty space above, no words or logos.
The empty space gives you somewhere to add a title later. Asking for no words reduces the need to clean up invented lettering, though you should still inspect the result.
Generate a draft that fits the page
- In OGAD, open Models and download a supported local image-generation model. Choose an option that fits your computer’s memory.
- Select it, open Chat, then use + → Generate image.
- Enter your visual brief and start with that model’s default settings.
- Inspect the draft as a small thumbnail and at a larger size. Keep the subject clear at both sizes.
- Open a useful result and select Download.
- Crop and add any exact headline in your normal image editor before using it on the blog.
The free desktop app includes local image generation. A supported SDXL model is a practical starting point for illustration experiments; the catalog has options with different visual tendencies. Choose based on the output you need and the memory available, without assuming every model runs on every computer.
Choose a size for the place the image will appear
Before generating, open Image options and use Size. The checked desktop controls offer square sizes, including 512 × 512 and 1024 × 1024. Use a size supported by your model and available memory. A smaller draft can help you choose the composition; inspect the final-size generation separately.
For a wide blog banner or a 16:9 presentation slide, leave room around the subject and crop the saved image in your normal editor. The square Size control is not an arbitrary aspect-ratio selector. Check your publishing layout’s required dimensions before the final crop, and do not crop away the part that explains the idea.
Changing generation size can change the composition. A new larger generation is not an exact enlargement of your first image. Review it at the size readers will see, then add any exact headline or labels outside the image generator.
Make the image specific to the article
Change the subject before adding more decorative detail. “A person at a desk” could fit thousands of posts. “A quiet desk with one notebook and all other tools put away” gives a focused-work article a clearer visual idea.
You can ask for a small set of variations by generating them one at a time:
- A close view with one clear subject for a thumbnail.
- A wider scene with empty space for a headline.
- A simpler treatment with fewer objects for an inline image.
Keep the model and palette consistent while you compare the layouts. Save the useful prompts with the images. This makes it easier to return to a direction later, without promising identical results across future generations.
Keep facts and interface details under your control
Use generated illustrations for concepts and scenes. If the article teaches a real product workflow, use a verified screenshot for the controls. If it presents data, make the chart from that data rather than asking an image model to draw plausible bars.
Inspect hands, repeated objects, stray text and misleading symbols. Add real logos only through the correct source and your normal layout process. Write alt text that describes the final image rather than repeating a list of search keywords.
The illustration should support the article’s point. If it suggests a capability the product does not have, change it even if it looks polished.
Work offline after setup
Use the downloaded local model and turn off optional prompt enhancement for your first run if you want to avoid a second model dependency. You can disconnect internet access and generate a simple draft to check the route.
This guide follows the local image workflow in OGAD 0.0.51. Your final blog upload needs a network connection; creating the illustration locally is the part that can work offline.
Make the image for the article you are writing
Download OGAD, write a one-sentence visual brief and generate a first draft. Choose the version that makes the article easier to understand, then crop it and add exact text in your editor. Give the post an image made for its idea.
