How the Seedream Prompt Generator Works

Move from an open-ended idea to a structured prompt in three focused steps.

  1. 01

    Start with text-to-image, single-image editing, or multi-reference creation.

  2. 02

    Describe the creative goal

    Add purpose, subject, composition, style, lighting, and constraints where useful.

    Review the optimized prompt, copy it, or hand it to the homepage generator with its settings intact.

Anatomy of a Strong Seedream Prompt

Strong prompts connect creative intent with concrete visual direction instead of stacking disconnected keywords.

Weak prompt

A stylish coffee maker ad, cinematic, high quality.

Optimized prompt

Create a premium launch visual for a compact matte-black travel coffee maker, shown at eye level on a pale stone counter. Use soft morning window light, restrained warm highlights, and generous right-side negative space for a campaign headline. Emphasize brushed metal, precise edges, and an uncluttered editorial mood in 16:9 at 2K.

Purpose and subject
Explain what the visual must achieve and what viewers should notice first.
Composition and style
Define framing, viewpoint, hierarchy, and the intended visual language.
Light, materials, and constraints
Add the details that control atmosphere, realism, exact text, and unwanted outcomes.

Prompts for Three Seedream Workflows

Each workflow organizes the brief differently so the final prompt stays actionable.

01

Text to image

Build a new composition from the goal, subject, visual direction, and output settings.

Create a clean editorial illustration of a modular urban garden for a sustainability report cover, using an isometric viewpoint and muted botanical colors.

02

Single-image edit

Separate the requested change from the details that must be preserved.

Change the setting to a rainy neon street at night. Preserve the product silhouette, logo position, viewing angle, and all printed label text.

03

Multi-reference creation

Give each ordered source image one explicit role before continuing to the image workflow.

Image 1 defines the product geometry. Image 2 provides the copper material finish. Image 3 supplies the studio lighting and background mood.

Built for Everyday Creative Briefs

Product marketing

Social and advertising

Match composition and aspect ratio to fast-moving campaign placements.

Editorial and infographics
