Flux 3 AI Prompt Builder

Build clear prompts for AI images and videos, copy them in one click, and open Flux 3 AI to generate.

Flux 3 AI Prompt Builder helps you write clear, structured prompts for AI image and video generation without starting from a blank box. Describe your subject, then choose from simple presets: • Image prompts: style, framing, lighting and mood • Video prompts: action, camera movement, framing, pace, lighting and mood • Extra details and things to avoid, such as text or watermarks The extension assembles everything into one readable prompt. Copy it with one click, reuse your five most recent prompts, or open Flux 3 AI to generate an image or video with it. Privacy The extension requests no browser permissions, does not read the pages you visit and does not send your prompts anywhere. Your drafts and recent prompts are stored only in this browser.
