AI prompt generator

Write your idea in a few words. After you sign in, the agent in your workspace chat turns it into a detailed prompt for the image or video model you choose, ready to copy or to run right there.

Write a detailed prompt for an AI image or video model from this idea: an Instagram ad for a small coffee shop, cozy morning light. Ask me which model it is for if I did not say. Cover the subject, the setting, the style, the light, the camera and the format, and give me the prompt in a block I can copy. Do not generate anything until I ask.
Idea · Coffee shop ad, morning light, Instagram
Model · Nano Banana 2.1, 4:5

Here is your prompt: "A small corner coffee shop at 8 a.m., warm sunlight through the front window falling on a wooden counter, a barista pouring latte art into a white ceramic cup, steam rising, pastries in a glass case, soft focus background, photographed on a 35 mm lens, natural colors, vertical 4:5 for an Instagram feed post, space at the top for a headline."

  • Say run it and I will quote the cost first.
  • Ask for a video version and I will add the camera move and the sound.

What is an AI prompt generator?

An AI prompt generator turns a short idea into the detailed instructions an image or video model needs. The model only sees what you write, so a prompt that names the subject, the setting, the style, the light, the camera and the format gives a closer result than a few words.

Each model reads prompts a bit differently. Some follow long natural sentences, some do better with a short list of details, and video models also need the action and the camera move. The agent writes the prompt in the form that suits the model you pick.

In Endless, the prompt is written in your workspace chat. You can copy it to use anywhere, or ask the agent to run it on Nano Banana, FLUX, GPT Image, Seedream, Kling, Veo or another model in your workspace, see the cost first, and refine the prompt from the result.

How it works

  1. 01

    Write your idea

    Type what you want to create in the box above, in your own words. Mention the model and the format if you already know them.

  2. 02

    Sign in and send it

    Create a free Endless account or sign in. Your workspace chat opens with the request already written. Send it, and answer the agent's questions about the model or the style.

  3. 03

    Copy or run the prompt

    The agent gives you the prompt in a block you can copy. Ask it to make the prompt shorter, change the style, or run it on a model and show you the cost first.

What people use it for

  1. 01

    Prompts for image models

    Turn a one-line idea into a full prompt for Nano Banana, FLUX, GPT Image or Seedream, with the style, light and composition spelled out.

  2. 02

    Prompts for video models

    Describe a scene and get a prompt for Kling, Veo or Seedance that covers the action, the camera move, the length and the sound.

  3. 03

    Variations of one idea

    Ask for five versions of the same prompt in different styles, then run the ones you like best.

  4. 04

    Consistent series

    Keep the same character, palette and look across a set of images by reusing the parts of the prompt that describe them.

  5. 05

    Prompts in English from any language

    Write your idea in Spanish, Portuguese or any language and ask for the prompt in English, or keep it in your language.

Frequently asked questions

  • Is the AI prompt generator free?

    You can start free. A free Endless account comes with the Free plan, which gives your workspace 100 credits when you create it and 50 credits every week. Writing a prompt is a chat turn, which spends a small amount of credits. Generating an image or a video from it spends more, depending on the model.

  • How is this different from image to prompt?

    This page starts from your idea, written in words. Image to prompt starts from a picture you already have and describes it as a prompt so you can make something similar.

  • Which models can it write prompts for?

    Any image or video model you name. For the models in your Endless workspace, such as Nano Banana, FLUX, GPT Image, Seedream, Kling and Veo, the agent can also run the prompt right away in the same chat. Some video models need a paid plan.

  • Can it run the prompt for me?

    Yes. Ask it to generate the image or the video and it tells you the model and the cost before it runs. The result is saved in your workspace, and you can ask for changes to the prompt from there.

  • Can I write my idea in Spanish or Portuguese?

    Yes. Write in any language. The agent can write the prompt in English or in your language, whichever you ask for.

  • Can I save prompts I like?

    Every prompt stays in the chat history of your workspace. To reuse a style often, ask the agent to save it as a skill, so it follows the same rules every time you ask.

  • Are my prompts private?

    Chats, prompts and anything you generate are saved in your workspace, private by default, and you decide who to share them with. Endless does not publish your prompts anywhere.
