About Closed on Sunday AI
Closed on Sunday AI is a small independent tool that does one thing: puts a person or pet of your choice in the middle of the Closed on Sunday choir. It is run by Chen Wenjian, an individual operator in China, and was built in October 2026 when the AI choir trend took off.
How it is made
- Lead picture: GPT Image 2 (via APIMart) draws a clean, full-body picture of the person or pet from your photo.
- Video: MiniMax H3 reference-to-video (via fal.ai) films 14 seconds at 1344×768.
- Motion: a faceless depth map of the original 14-second choir shot, so the crowd and camera move like the original.
- Music: an original gospel choir track written for this site with Suno, so videos carry no copyrighted recording.
- Safety: Waffo Prompt Sift for typed choirs, SeeAPI for photos and sampled video frames, plus the model’s own checker.
- Payments: Waffo Pancake as Merchant of Record; storage on Cloudflare R2; hosting on Vercel.
What we promise
Your photos and videos are private, deleted after 30 days and never used for training or marketing. Failed videos are returned to your balance. Example videos use AI-generated people and pets only.
