Create an image of a developer platform that automates code reviews, set in an abstract isometric workspace with floating code windows and connected nodes. Style: clean isometric 3D illustration with soft gradients. Lighting: soft studio lighting. Composition: subject on the right with clear space on the left for a headline. Mood: modern, trustworthy, innovative. Details: brand colours indigo and teal. It will be used for the landing-page hero of a developer tool, so use a 16:9 aspect ratio. Keep the frame clean and uncluttered.

How the FLUX prompt is structured
FLUX understands full sentences, so the prompt reads like a photographer's brief: subject, setting, lighting, composition, mood and where the image will be used.
Every prompt is built from the same modular parts — role, task, context (your audience and details) and output format — then rendered in the style each AI follows best. Change the AI in the drop-down and the same request is rewritten instantly.

- Tech hero illustration — for example “a developer platform that automates code reviews”.
- Blog cover image — for example “an article about migrating a monolith to microservices”.

Frequently asked questions
What is a FLUX prompt generator?
It turns a plain-language request into a structured prompt — role, task, context and output format — written the way FLUX follows best, so you get better answers on the first try.
Does this tool send my text to FLUX?
No. The prompt is assembled in your browser from templates. Nothing you type is sent to any server or AI until you paste it yourself.
Why does the prompt change when I switch AI?
Models are trained on different conventions: Claude responds well to XML tags, Gemini to Persona/Task/Context/Format, Midjourney to descriptors and --parameters, Suno to style tags and a lyric sheet. The generator rewrites the same request for each.
What if I leave a field empty?
The example shown in grey is used instead, so the prompt is always complete. Replace it with your own details for the best results.
Can I use these prompts for other software development tasks?
Yes. Pick the closest prompt type and describe your own task — the software development expertise in the role and context still applies.
Is the prompt generator free?
Yes — free, unlimited and no account needed.
