The butterfly
Green paper wings → pink fairy


Bring the photo of the costume that didn't go to plan — the paper wings, the trash-bag cape, the paper hat — and tell us what it was meant to be. AI dresses the same kid in the costume they were promised, and you get a ready-to-post 3-slide video.
Same kid, same pose — just the costume they were promised. Every kid here is AI-generated and doesn't exist.
Green paper wings → pink fairy


Trash-bag cape → velvet Dracula


Black hoodie and a paper cone → purple witch


It's a three-slide TikTok and Reels format, also searched as the “I'm So Sorry I Lied” costume trend. Slide one shows a flawless Halloween costume with the caption “When I was little I was a witch for Halloween.” Slide two admits it: “I'm so sorry… I lied.” Slide three is the real photo — the homemade costume in all its glory.
That first picture is usually made with AI from the real one, which is why so many versions of the im sorry i lied trend look so polished. The sorry I lied costume joke only lands when the kid in both pictures is clearly the same.
I'm Sorry I Lied handles both parts: the AI costume and the finished slides. You upload the real photo; we keep the face and pose, swap in the promised costume and give you the video plus every slide.
See how it works, step by step →Upload the real photo — you as a kid, or your own child, in the costume that didn't quite land.
Say what it was meant to be — a butterfly, a vampire, a witch. That line becomes the slide-one caption.
Download and post — two AI versions, each as a 3-slide 9:16 video plus the photo and slides. Ready in minutes.
