Chrome ExtensionFLUX.1 Image Prompt Generator
Generate optimized prompts for all FLUX.1 variants (Schnell, Dev, Pro, Ultra). Fill in your creative vision using structured inputs and let AI craft the perfect prompt — leveraging FLUX.1's strengths in text rendering, layered compositions, and contrasting aesthetics.
Be specific: describe who/what is in the image with details
Generated Prompt
Fill in the form and click "Generate" to create an optimized FLUX.1 prompt.
Tip: Be as specific as possible with your subject description. Instead of "a dog," try "a golden retriever puppy with a red bandana."
FLUX.1 Tips
- • FLUX.1 excels at text rendering — specify font, size, color, placement, and effects (neon, shadow, distortion)
- • Use layered descriptions: clearly define foreground, middle ground, and background in order
- • Contrasting aesthetics work beautifully — try different moods in different parts of the image
- • For photorealism, include device name ("shot on iPhone 16"), aperture, and lens type
How to Use the Prompt Generator

Click "Generate" and our AI will craft an optimized prompt following FLUX.1 best practices, including hierarchical layer descriptions and precise text specifications.
Copy & Create
Copy your prompt and paste it into any FLUX.1 platform (Replicate, fal.ai, getimg.ai, ComfyUI). Regenerate for variations or tweak your inputs and try again.
Frequently Asked Questions
What is FLUX.1?
FLUX.1 is Black Forest Labs' groundbreaking image generation model, available in four variants: Schnell (ultra-fast, 1-4 steps), Dev (balanced quality/speed), Pro (API access, high quality), and Ultra (maximum quality). It's known for exceptional text rendering, layered compositions, and prompt adherence.
How does this prompt generator work?
You fill in structured inputs including your preferred FLUX variant. Our AI combines these with FLUX.1 best practices — using layered descriptions, precise text specifications, and contrasting aesthetics — to produce an optimized prompt ready to paste.
What's the difference between FLUX variants?
Schnell is ultra-fast (1-4 inference steps) for quick iterations. Dev offers balanced quality and speed (20-30 steps). Pro provides high-quality API access. Ultra delivers maximum quality for the most detailed work. Our generator adapts the prompt complexity based on your selected variant.

Can FLUX.1 render text in images?
FLUX.1 is one of the best models for text rendering. Specify font style, size, color, and placement. You can even include multiple text instances with different styles, and add effects like neon glow, shadows, transparent outlines, and distortion.
Where can I use the generated prompts?
The prompts work with FLUX.1 on platforms like Replicate, fal.ai, getimg.ai, ComfyUI, and the official Black Forest Labs API. They also produce excellent results in other text-to-image models.
What makes FLUX.1 unique for layered compositions?
FLUX.1 excels at precisely controlling different image layers. You can define what appears in the foreground, middle ground, and background with remarkable accuracy. It also handles see-through materials (glass, ice, plastic) better than most models.
