CharaSync is a hosted web app that generates images and short videos from a saved library of character and object references, keeping one subject across new scenes. It needs an account and calls GPT Image 2.5 and Seedance 2.0; credit plans run from free (images only) to Pro and Max, which add video. Note before using it: upload only references you own or have permission to use, and no output is guaranteed cleared for commercial use.
