H3 Prompt Writer 🆎
Type what happens, one line for each moment, and leave a blank line to cut to a new place. Connect up to four pictures, give each one a job such as person, place or outfit, and name them @1 and @2 in your lines. Connect a video to copy its moves or carry it on. Add a voice or a song and it writes the lines H3 needs. H3's own six parts go through as they are. Connect a small text model and it fills in a one-line idea.
