Lookalikey vs Colorin

Lookalikey lets you create personalized greeting cards, posters, and canvas prints by swapping a face, pet photo, or custom name into pre-designed templates. Pick a design for birthdays, anniversaries, thank-you notes, and dozens of other occasions, upload a photo, preview the result in about 30 seconds, and order a printed card or digital download.

The platform offers face swap, pet swap, and text swap modes across hundreds of themed templates. Physical cards ship in the UK and US, with digital downloads delivered instantly.

Lookalikey is run by a small family team that launched the service in May 2024 and has served over 300,000 customers.

Colorin is a web platform for creating custom coloring books from text prompts, photos, or locked characters. You brainstorm page ideas in batch, generate many pages at once in a consistent style, and export print-ready PDFs sized for home printing or Amazon KDP and Etsy listings.

Most coloring tools stop at single pages. Colorin is built around full book workflows: its ideas generator turns a theme into dozens of page concepts you can select and send to batch generation, and character lock keeps the same character across every page while scenes change.

The platform offers six art styles (Cartoon, Kawaii, Storybook, Minimalist, Intricate, and Zentangle), built-in page editing, cover design, and KDP-ready trim sizes with margin presets. Parents, teachers, and independent publishers use it to make personalized activity books or sell commercial titles without juggling separate design tools.
