VideoSI

videosi (videosi.io) is an AI body swap and character swap tool for short videos. You upload a clip you saw, up to 60 seconds, plus one photo of yourself or of someone who agreed, and videosi remakes the clip with that person as the lead. The original moves, camera angles, timing and setting stay the same, so the result still reads as the same viral trend.

Unlike a face swap, which only replaces a face, an AI body swap replaces the whole person: body, outfit and movement. Before anything renders, videosi breaks the clip into shots (who moves where, the camera, the setting) and shows the exact price. The breakdown is free. You then choose Body swap, which keeps the scene and swaps the character, or Full remake, which rebuilds the whole scene.

Clips longer than one model generation (15 seconds) are split into segments on the original's own cuts and joined into one file. A fast model returns a video in about 5 minutes, a higher-quality one in about 20.

videosi also offers viral AI video trend effects (AI hug, AI kiss and more) and 7 free creator tools with no sign-up: Video Frame Extractor, Video to Prompt, TikTok Script Generator, TikTok Safe Zone Checker, TikTok Video Size checker, TikTok Caption Generator and Hook Generator.

videosi is for adults 18+ and only for people who consented. Photos of celebrities and public figures are refused, sexual content is blocked, uploads are deleted within 30 days and are never used to train AI models.
