YouTube Shorts Automation API
Build an automated YouTube Shorts pipeline. The AITuber API generates vertical 9:16 videos optimized for YouTube Shorts, complete with AI narration, visual generation, and word-synced captions. Create dozens of Shorts per day, each with unique scripts, voices, and visual styles. Perfect for running faceless YouTube channels at scale.

Every video is generated in the exact 9:16 aspect ratio that YouTube Shorts requires. No cropping or resizing needed.
Captions are timed word-by-word to the narration. Multiple styles available including the popular MrBeast-style wrap highlight.
Just describe a topic. The API writes a complete script, generates visuals, records narration, and renders the final video.
