Free AI Prompt Generator
Pick a look from the dropdowns and get a polished, ready-to-use portrait prompt.
Great portraits start with a great prompt — but writing one that nails the expression, framing, lighting, lens, and grade is hard. This tool does the writing for you: choose from curated dropdowns and Gemini 3.5 Flash weaves your selections into a single, photographer-grade prompt you can paste straight into any text-to-image model. Leave a dropdown on 'Any' and the model fills the gap with a complementary choice.

What you can do with it
Headshots & profiles
Dial in a clean, professional look — tight headshot, eye level, soft window light, corporate grade — and get a prompt that produces consistent, on-brand portraits.
Editorial & fashion
Push for drama: low angle, rim light, golden hour on a rooftop, moody film grade. The generator turns those choices into a rich, runway-ready prompt.
Character & concept art
Explore a character's age, wardrobe, mood, and setting across dozens of variations — change one dropdown, regenerate, and compare directions fast.
Learning prompt craft
See how a professional prompt is structured. Read the output to learn which words and details actually move an image model — then adapt them in your own work.
Frequently asked questions
- Does this create an image or a prompt?
- It writes a prompt — the carefully-worded text you paste into an AI image generator to create the portrait. Keeping prompt-writing separate lets you use the result with whichever image model you prefer, and it costs only a fraction of an image generation.
- Which image generators does the prompt work with?
- Any text-to-image model. The generated prompt is plain descriptive language, so it works with FLUX, Nano Banana, Midjourney, Stable Diffusion / SDXL, Ideogram, and the image models in the Artifio workspace.
- What if I don't pick every dropdown?
- Leave any dropdown on 'Any' and the model chooses a complementary detail for it. You can specify as much or as little as you like — even a couple of choices produce a complete, usable prompt.
- Is the portrait prompt generator really free?
- Yes. Signed-in members get a monthly free allowance shared across all of our free tools. When you reach it you can top up to keep going, or wait for the allowance to reset next month.
