Definition
ToonBooth turns your photos into a black-and-white webtoon caricature strip that looks just like you, your family, or your friends. Modes range from classic photo-booth-style strips to story-driven four-panel comics, and each produces a completely different result. Upload photos of multiple people and they’re automatically composed into one group strip.
Problem Statement
Photo-booth strips only exist offline and stay close to a lightly retouched photo. There’s no easy way to get a caricatured, comic-style strip of yourself. ToonBooth sits between the two, available anywhere, but fully reimagined in a webtoon style.
Core Audience
- Couples, families, and friend groups: Users who want to turn a photo together into something more special
- Photo-booth fans in their teens through 30s: Users looking for a shareable result for social media
- Fans of caricature and webtoon-style content: Users who want a comic reinterpretation of themselves rather than a realistic photo
