Synthesia makes talking-head avatars. Long Story makes narrated films.
Synthesia is a leader in AI avatar videos for corporate training and explainers — a presenter on screen, reading a script. Long Story is for the opposite style: faceless, narration-led long-form content where the visuals are the story, not a talking head. If you're building a documentary, sleep, or lore channel, you don't want an avatar — you want hours of narrated scenes.
