overview
An edtech startup based in Greece, building a mobile learning app for children aged 4 to 10. The app offered courses in language, maths, and general knowledge, with each course featuring a unique set of illustrated screens and interactive elements.
The app's visual identity was built around a distinctive flat vector illustration style — friendly characters, clean lines, bold colours, and a playful but educational tone. Every new course needed 30 to 50 unique illustrations, including character poses, icons, scene backgrounds, and interactive elements. The company was also expanding into Arabic-language content, requiring a new set of illustrated Arabic alphabets where each letter transformed into a creative, child-friendly illustration.
The Challenge
The company had been working with a freelance illustrator to produce all visual assets. The illustrator was talented and understood the style perfectly. But the bottleneck was capacity: a single illustrator producing 30 to 50 illustrations per course, with each illustration taking 2 to 4 hours of work.
Single illustrator bottleneck
Entire visual output depended on one person — one course at a time, no way to scale.
$80K–$135K annual cost
12 planned courses at $6.75K–$11.25K each in illustration fees alone.
Roadmap blocked
Fully written courses sitting idle, waiting on illustrations before they could launch.
The Arabic alphabet project alone required 28 unique illustrated letters, each with multiple variations. The freelancer estimated 6 to 8 weeks for this project, at a cost of roughly $15,000.
Our product roadmap was being dictated by illustration capacity, not by content readiness.
How We Solved It
We started from the company's existing illustration library. Line weights, colour palette, character proportions, compositional patterns. The model learned all of it directly from the assets the team had already produced.
1. Training on the existing illustration library
We used the full library of existing illustrations as training data. The model learned the specific characteristics of the style: line weights, colour palette, character proportions, shading techniques, and compositional patterns.
2. Solving the Arabic alphabet challenge
For the Arabic alphabet project, we worked with the company's educational content team to understand the pedagogical requirements. Each letter needed to be recognisable as both an Arabic character and a playful illustrated object. The model was trained to produce illustrations that met both the visual style requirements and the educational clarity standards.
3. Humans directing, AI producing
The company's design team directed the creative output, selecting illustrations, requesting adjustments, and making final refinements. The AI handled the production volume. The humans ensured every illustration was educationally sound and visually on-brand.
