FAQ

Frequently asked questions

Which AI image models can I compare?

Promly runs models from OpenAI (GPT Image), Black Forest Labs (FLUX), Google (Nano Banana) and Recraft — a dozen models across five tiers — so you can put them head-to-head on the same prompt.

Do I have to write a prompt for this?

Yes — the compare tool (the Direct Kit) is the one place in Promly where you type a prompt, because it's built for power users testing models. If you'd rather not write prompts, use a guided Kit like the Sticker or Comic generator.

Why compare models instead of picking one?

Different models win on different prompts — one nails photoreal, another nails text or style. Comparing on your own image is faster and cheaper than subscribing to each provider to find out.

Is it free?

You get 15 Pixels free on sign-up with no credit card — enough to run your first side-by-side comparison. Comparing more models in one run earns a volume discount.
