How it works
Three steps to a finished video

Why VigenFlow
Not another clip tool.
Most tools clip, caption, or repurpose existing footage. VigenFlow creates from scratch: a full production pipeline in one command.
Review loop nobody else has
Every agent has a dedicated reviewer. Script scored on hook, arc, and CTA. Images checked for watermarks, duplicates, and visual consistency. Failed steps auto-retry up to 3×.
Review & regenerate any scene
Not happy with a scene's image or voice? Review the output, regenerate just that scene, and re-assemble. Full manual control, no need to restart the whole pipeline.
Character consistency across videos
Seed a character once per channel profile. Same face, same visual style, every scene of every video. Works with Imagen 3 and Pollinations FLUX.
Your keys. Your machine. Zero subscription.
$0/video is real: Gemini free tier for LLM, Kokoro (local) for voice, Pollinations (free) for images. Paid providers optional, and you bring your own keys.
