What does the AI prompt generator do?

It turns a short idea into a detailed prompt. For images it covers the subject, style, lighting, camera and composition, with a negative prompt when the model uses one. For video it describes the action, the camera movement and the pacing. For chat it sets out a role, the task, the context and the answer format. Each run also gives you two or three variations.

Is the prompt generator free?

Yes. You can try it without an account, and a free account gets a few prompts every day. Paid plans give you many more.

Which AI models does it write prompts for?

You can aim a prompt at Midjourney, Nano Banana, GPT Image or FLUX for images, Wan, Veo or Kling for video, and ChatGPT, Claude or Gemini for chat. If you don't pick a model, you get a general prompt that works in most tools.

How do I write a prompt for ChatGPT image generation?

Describe the scene in full sentences: the subject and what it is doing, the setting, the style, the lighting and the framing. Put any words that should appear in the image in quotes. The AI prompt generator does this for you: choose Image, set GPT Image under options, then copy the result into ChatGPT or send it to Zemith's image tool.

How are image, video and chat prompts different?

An image prompt describes one still picture. A video prompt also describes movement: what happens, how the camera moves and how the shot unfolds. A chat prompt tells a text model what role to take, what to do and how to format the answer.

Can I create the image or video right away?

Yes, on a paid plan. Tap Generate this image or Generate this video to open Zemith's Creative Studio with the prompt already filled in, or Use it in chat to start a chat with it. Image and video generation is on Zemith's paid plans (video on Plus and up). The prompt generator itself is free to try.

I already have an image. Can I get its prompt?

Yes, with Zemith's Image to Prompt tool. Upload the picture and it writes a prompt that describes it, which you can edit and reuse.

Prompts for ChatGPT image generation

ChatGPT's image generator works best with a clear description, not a pile of keywords: what the subject is doing, where it is, the style, the light and the framing, with any words that must appear in the image in quotes. Pick Image, choose GPT Image under options, and the generator writes the prompt that way. Paste it into ChatGPT, or generate it in Zemith.

Example, from the idea “a bakery window at sunrise”

A small neighborhood bakery window at sunrise, seen from the street: a deep-set glass display window framed in peeling mint-green painted wood, its sill crowded with rustic loaves, golden croissants, and a tray of glazed fruit tarts on crumpled parchment. Inside, a flour-dusted marble counter and a rack of cooling bread recede into warm shadow, while a single brass pendant lamp still burns above the till. Outside, cobblestones glisten with leftover dew, a chalkboard easel leans against the wall reading "Fresh Bread Daily" in looping white chalk, and a bicycle rests at the curb in soft focus. Shot as a slightly low three-quarter view at eye level, 35mm lens at f/2.8, shallow depth of field with the pastries sharpest and the street falling away. Low golden sunlight streams from the left, raking across the glass, catching flour motes drifting in the air, with cool blue fill from the shadowed side and a faint lens flare on the upper pane. Amber, cream, and pale sage palette, warm Kodak Gold tones, fine film grain, a quiet early-morning mood with a single pigeon perched on the sill.
