The context
Horizon Humain is a human resources consulting firm that supports growing small and midsize businesses. Its founder, Myriam Allouche, produces a lot of visual content for the firm's website, social media and communication materials. Creating illustrations and infographics, or adapting photos to the brand style, meant either hiring an outside provider or mastering complex AI prompting tools.
The goal: design a simple, custom tool that generates all these visuals in Horizon Humain's art direction automatically, with no prompt to write.

What I did
Analyzing the art direction
A study of Horizon Humain's visual identity: colors (purple, white, dark gray), a caring and professional tone, and the types of visuals used on the website and social media. This analysis was the basis for calibrating the generation models.
Building the app with vibe coding
The full web app was built with Claude Code. Its interface lets the user create illustrations and infographics and adapt photos to the brand style without writing a single prompt.
Integrating Gemini 3 Pro Preview
The app is powered by Google's Gemini 3 Pro Preview. It creates original illustrations, generates LinkedIn infographics with built-in text, and transforms existing images to match Horizon Humain's visual style, in every aspect ratio needed.
Style personalization through favorite images
A feature that lets the client pick favorite images to refine the style of the next generations. The tool learns from these visual preferences and produces results that match expectations more and more closely.
Deployment on Vercel with protected access
The app is deployed on Vercel with access restricted by email address. Only authorized people can use the tool. Updates ship continuously with no service interruption.
