Hotel Lobby AI - Turn any two photos into a viral orange-booth duet video

Hotel Lobby AI turns two photos (friends, couples, pets or cartoon characters) into a short duet video staged in the minimalist orange recording booth that's all over TikTok and Reels. No prompts, no editing: drop one photo per performer and get a watermark-free vertical 9:16 or 4:3 video in minutes. Your first video is free, no card needed. Then $4.99 for 3 videos, or a monthly plan. Failed videos are refunded, and uploaded photos are deleted after generation.
