What is ByStory?

ByStory is an AI drama tool. An AI short-drama studio that coordinates six specialized agents for world-building, characters, scripts, cinematic video, music, voice, and localization into 34 languages.

ByStory is an AI production studio aimed at short-form drama. Instead of exposing a single video generator, it runs a pipeline of six specialized agents that divide the work: world-building, character creation, scripting, cinematic direction, and localization. A writer, marketer, or hobbyist brings a premise, and the system develops it into a finished drama episode rather than a loose collection of clips. The stated promise is delivery in minutes with no writing experience required. The video layer is built on third-party models rather than in-house ones: Seedance 2.0, Veo 3.1, and Kling 3.0 handle clip generation, either from a text prompt or from reference images supplied by the user. Around that core sit soundtrack and narration tools. Music comes from Lyria, driven by descriptions of genre, mood, and instrumentation, and generated tracks can be dropped directly onto the timeline's Music lane or iterated into a library of variations. Voice work draws on 30 character voices spanning 75 languages, so a cast can be voiced rather than merely captioned. Localization is treated as a first-class step, not an afterthought. Scripts and captions can be translated into 34 languages with an emphasis on preserving nuance, which suits creators who plan to publish the same series across several regional audiences. In practice the tool behaves like a small studio in a browser tab: draft the premise, let the agents build the world and cast, review generated footage and audio on a timeline, then push the result out in multiple languages. It sits closest to AI video generators such as the models it wraps, but the framing is different. Those tools answer a single prompt with a single clip; ByStory answers a story idea with a structured episode. The trade-off is control and cost transparency. Anyone who simply needs one cinematic shot will find dedicated generators more direct, and anyone with an established production pipeline should confirm how much fine-grained editing the timeline allows before committing.

How do you use ByStory?

1Describe your story spark
Open the site and start a new project with a short premise. The copy stresses that no writing experience is needed, so a sentence or two of setup is enough to begin.
2Let the agents build world and cast
The six agents take over world-building and character creation first. Review the setting and characters they produce before the script stage locks them in.
3Review the script and direct the shots
Check the generated script, then let the cinematic direction agent plan clips. Footage is produced with Seedance 2.0, Veo 3.1, or Kling 3.0 from prompts or reference images.
4Score the episode with Lyria
Describe genre, mood, and instrumentation to generate an original track, then place it on the timeline's Music lane. Generate variations until one matches the scene.
5Assign voices and localize
Pick from the 30 character voices for narration, and translate scripts and captions into any of the 34 supported languages before export.
