Sample prompts to copy

Tested starting points for image generation on Multio. Copy, paste, edit to fit your task.

I want a logo for a coffee shop called "Drift". Describe 3 directions in detail — visual style, color palette, mood.
Critique this image as if you were an art director. What is working? What is not? Where would you push?
Write me a detailed image prompt for [scene]. Include lighting, camera angle, style, and mood.
I generated this image but it has [flaw]. Rewrite my prompt to fix it.

Step-by-step workflow

Plan the image with a vision model first. Use Gemini 3.1 Pro to talk through the visual direction before generating. Prevents "wrong but technically correct" outputs.
Get a detailed prompt written. Ask GPT-5 or Claude to write you a detailed image prompt — style, lighting, camera angle, mood, palette.
Generate and critique. After generation, paste the result back to a vision model and ask for a critique. Iterate the prompt based on what is missing.
Use Multio image tools on paid plans. Premium plans include image generation directly in chat — no app switching.

Common pitfalls — and how Multio handles them

Vague prompts produce generic output
Specify lighting, camera angle, style, mood, palette. The more specific the prompt, the more specific the output.
Critique is generic
Ask the model to compare to a specific reference. "Make this feel like [artist/movie/aesthetic]" produces sharper feedback.
