LongStories.ai is a web-based AI video generator built for long-form content rather than short clips. It creates story videos and music videos of up to 15 minutes from an idea, a pasted script, an uploaded voice recording or a song, and it aims to keep characters, styles and voices the same from the first scene to the last.
The product is organized in three layers: a single video, a series of videos, and a universe that holds a shared world. The site reports more than 20,000 videos created and more than 10,000 creators, figures the company states itself.
How does LongStories.ai work?
A user starts from one of four inputs: a few lines describing an idea, a finished script, a voice recording, or a song. For an idea, LongStories writes the script and plans the shots. The user then picks a visual style, decides who speaks (a narrator, the characters, both or nobody) and chooses an animation level: Mini, Fast, Pro or Ultra, or still images.
After selecting Generate Video, the result opens as Story Cards, each holding its shots and its words. Users can fix one shot, change the text, preview the result and export. When the story continues, Next episode creates a new video that keeps the cast, look, voices and story so far.
Key features of LongStories.ai
Consistency is the central feature. Characters, places and objects are stored in a library and reused across videos, and series carry the cast and a short record of each episode forward. Universes add a world-level layer with cast, lore, rules, art direction, audience and a single visual style.
Other tools round out the workflow: a song generator with auto lyrics, custom lyrics or instrumental output across 16 genres and 10 moods; narrator and character voices with captions; clip upscaling to 1080p, 2K or 4K; and posting or scheduling to YouTube. Higher tiers add API access, custom voices, custom video model selection and experimental consistency controls.
