AI-Generated Image Caption Overlay Workflow

This n8n workflow automates the process of downloading an image, generating a descriptive caption using AI, and overlaying the caption directly onto the image. It integrates multiple nodes including image processing, AI language models, and image editing to create visually enhanced images with captions, ideal for posts, social media, or watermarking. The workflow begins with fetching an image from a URL, then uses Google’s Gemini AI model to produce a fitting caption based on the image content. It calculates optimal text placement, overlays the caption onto the image, and produces a finalized image with embedded text. This automation streamlines content creation, making it useful for bloggers, marketers, or social media managers who want to generate engaging visual content quickly.
