Automatically generate and overlay captions on images with AI

Feeds an image to an AI model, writes a fitting caption, and overlays the text directly onto the picture.

How the work actually flows

A straight line.

The problem it solves

You need captioned images for social posts on a regular basis, but writing and placing text on every image by hand is slow and the results are inconsistent from one post to the next.

Who it fits

Social media managers or content creators who need quick, on-brand captioned images.

How it works

  1. An image is pulled in from wherever it's stored
  2. The image is resized to fit AI processing limits
  3. AI looks at the picture and writes a caption title and text
  4. The caption is positioned and overlaid onto the original image
What you get

Captioned images ready without opening an editor

You get a captioned, ready-to-post image generated automatically from any picture you provide.

What you get

A finished image with an AI-written caption already placed on it.

What you need

A Google Gemini API key and a Google Drive account.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
