How Screenshot API can be used with OpenAI-4o Image Generator
OpenAI-4o can now generate images too. The model generates good images & is becoming quite popular.
Using it with CaptureKit Screenshot API, can bring in some awesome use cases that we thought of sharing in this blog.
If you are a marketer, you can spin those raw screenshots into stunning visuals that give the essence of the product.
I will just give you an overview of the workflow first to help you understand how this automation can be thought of in action.
And then I will give 12 use cases of this combination that you can use in marketing.
Let’s get started!!
Automation Workflow of Using OpenAI-4o with CaptureKit
You won’t be taking manual screenshots and uploading it every time on the image generating module.
If you want this to work autonomously, here’s what you would need to do.
Now this is something of a general overview, depending upon your needs, programming language, or no-code tools you are using you may tweak it to better fit in your needs.
-
Pick A Trigger
Since the system should work autonomously, start with a basic trigger in your workflow. It can be uploading the URL of the webpage you want to make visual for.
-
Call Screenshot API
This second step takes that URL to CaptureKit for taking the screenshot hero section of the image.
-
Generate a Prompt for Image Generation
Using this hero section’s screenshot, our autonomous workflow should generate a simple prompt by understanding what the product is about.
So suppose we give in typerform (customer feedback tool) to it, the AI model generates a simple prompt “Please generate people discussing their customer feedback and take this screenshot as background image”
It will take some manual system prompts to train your model here.
-
Send This Image & Prompt To OpenAI-4o to Get Output
From the output of our second and third steps, we send the input for this model. An image is built following the prompt. We can now put it in a database or directly upload it, where it can be used.
See the image generated using the prompt generated in our 3rd step and the screenshot taken in the second step.
