Tips for better results
Small prompt changes make a big difference.
- Put the headline in quotes — "NEON NIGHTS" — so the model renders the exact text.
- Keep on-poster text short. Headlines and a date render far more accurately than paragraphs.
- GPT Image 2 has the best text rendering — use it when accurate poster typography matters most.
- Name a style ("Swiss typographic", "cinematic key art", "retro 80s") to lock the look.
- State your color palette and mood ("high contrast neon", "cold moody blues") in plain words.
- Generate several layouts, then refine the winner with image-to-image editing.
Frequently asked questions

Yes. You can design posters with the free Z-Image model, no credit card needed. For sharper text and higher quality — GPT Image 2, Flux, Nano Banana Pro — sign up and get 3 free credits plus 1 free trial on every premium model.
Can the AI put accurate text on my poster?›
Yes — especially with GPT Image 2, which has the best text rendering of current models. Keep the wording short (a headline and a date) and put it in quotes for the most accurate results.
Can I use the posters commercially?›
Yes. All posters come with a commercial use license — for events, products, advertising and prints.
Will there be a watermark?›
No. Posters generated on Raphael AI are watermark-free.
Can I print the poster in large format?›
Yes. Several models output up to 4K, which works for most print sizes. For very large formats, generate at the highest resolution available.
How is this different from Canva poster templates?›
Template tools give you the same layouts everyone uses. Raphael AI generates an original poster design from your description, so you get unique key art rather than a filled-in template.
