ByThen

ByThen is an AI video producer designed for long-form storytelling, enabling creators to turn ideas into narratively driven videos within a single workflow. It provides scriptwriting, key assets, storyboarding, voiceover, video generation, music, and timeline editing, exporting each project as an MP4 file. The platform targets content creators who produce structured, narrator-led videos such as faceless YouTube videos and educational explainers.

ByThen operates through a five-step process that starts with setting a creator profile, then generating or adding a script, building characters and environments, reviewing a scene-by-scene storyboard, and finishing with a video ready for export. The workflow emphasizes consistency across scenes and keeps all assets saved for reuse in new projects.

The tool emphasizes a single end-to-end workflow, with a project that can run up to 30 minutes and a creator profile that remembers characters, environments, and visual identity across videos. It offers built-in controls to adjust the script, replace clips, and shape the visual identity at every stage, ensuring the final output remains aligned with the initial creative direction.

It notes limits on video duration, a fixed frame rate and resolution, and credit-based usage.
