## What is Sajin?

Shoot now, develop later. Sajin is an AI darkroom: pick a preset, hand over one photo, and it comes back in about 30 seconds.

Studio presets: 1994 photo studio portrait, AI profile, ID photo (not for passports or government IDs), hanbok, photocard, black-and-white studio, four-cut photo booth sheet, travel snap, 90s teen movie poster, superhero team poster.
Play presets: die-cut sticker, webtoon panel, 3D character, action figure box, pet portrait, anime cel, caricature, Korean minhwa portrait, claymation, pet sticker.
Seasonal limited-time presets come and go.

Your first 5 photos are free, then 1 free photo every week. Need more? Buy credits or subscribe to Sajin Plus. Photos without a visible face are returned without using a credit.

Photos are sent to an image-generation AI (US servers) for processing and the original is deleted from our servers afterwards. Results are AI-generated images; studio presets carry an AI mark.

Sajin Plus renews monthly; cancel anytime in your App Store account settings at least 24 hours before the current period ends.
