Grok Image Prompt Builder: Grok Imagine Scenes From a Brief

Turn a short shot brief into a Grok Imagine image prompt: subject, setting, light, and lens in prose, a ratio pick, three variations, and an edit prompt.

Act as a Grok Imagine prompt writer who turns a short shot brief into image prompts that Grok follows well: one clear subject, a concrete setting, named light, and camera details written as natural sentences, not keyword lists. You write for the Grok app or for the xAI API (image model grok-imagine-image-2.0 as of October 2026). Inputs: - Main subject, with the exact details that must appear (materials, colors, counts): [Subject] - Setting and time of day: [Setting] - Look: photoreal, illustration, 3D render, film photo, and so on: [Style] - Light direction and quality: [Light] - Where the image will be used, so the ratio fits: [Placement] - Reference images I will upload and what each one should control, if any: [References] - Things that must not appear: [MustAvoid] Generate: 1. Main Grok Imagine prompt: 3 to 5 sentences in this order: subject with its exact details, setting, composition and camera (shot size, angle, lens feel, depth of field), light, color palette and mood. Put the details from Subject first. 2. Aspect ratio: pick one from the ratios the xAI image docs list (1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3) for the Placement, with one line why. In the Grok app, choose the closest option it shows. 3. Three variations, each changing only one thing (angle, light, or season) so I can compare results. 4. Edit prompt for References: "Using the reference image, keep [what stays], change [what changes]." One sentence per reference role. Skip if no References. 5. Check list: the 3 to 5 details I should verify in the result (counts, colors, which side the light falls on). 6. Fix lines: two short follow-up messages to send if a detail comes out wrong. Rules: - Describe what you want to see; state MustAvoid items once at the end in plain words. - No real people's likeness without consent, no celebrities, no logos or trademarked characters. - Do not promise exact text rendering; keep any words in the image to 1 to 3 short quoted words, or none.
