The problem, and how we approached it.
The problem
Most gifts are interchangeable: they would work for anyone, which is the opposite of the point. Custom illustrated portraits exist, but they are slow, expensive and a gamble until they arrive.
People want something personal, fast, and they want to see it before they pay.
Our approach
We designed the whole funnel around a free, full-page preview. A three-step creator (story, photos, design) generates a complete comic that keeps the people recognizable.
Customers only pay once, when they want the clean files. No subscription and no account.
Six pieces, one product.
- Story templatesLove Story, Little Hero, Family & Friends, and more, built around real occasions.
- Five art stylesDreamy anime, manga, heroic comic, 3D animated and classic comic.
- Private uploadsPhotos are deleted within 24 hours. Guidance helps people pick photos that work.
- Free previewThe whole page is generated and shown, watermarked, before any payment.
- One-time checkoutFrom 1 page to a 3-page story with a custom cover. No account required.
- Print-ready deliveryWatermark-free PNG and A4 PDF, ready to share or print.
Under the hood
Preview-first, by design.
Giving away the full result before payment only works if generation is dependable. The pipeline takes the chosen story and style, keeps each person's likeness across panels, and produces the watermarked page; payment unlocks the clean files.
