Question 1

Is Image to Prompt free?

Accepted Answer

Image to Prompt is one of the Free tools on Banana2.1 — you only need a signed-in account. Sign-up takes a few seconds and needs no credit card, and every account also gets 10 free credits each month for Nano Banana 2.1 image generation.

Question 2

What is the prompt actually used for?

Accepted Answer

Most people use reverse prompting in three ways. First, to recreate a look they liked with Nano Banana 2.1 or another model. Second, to learn what makes a prompt work by studying how strong images get described. Third, to make variations — get the prompt, tweak a few words, and generate something new with the same feel.

Question 3

Which AI writes the prompt?

Accepted Answer

A vision-capable AI model analyzes your upload and writes the prompt. Our instructions push it to name style, composition, lighting, and camera terms, so the result is far more specific and prompt-friendly than a generic image caption.

Question 4

How do the prompt styles differ?

Accepted Answer

Each style uses its own instructions. Nano Banana 2.1 gets clear full sentences that spell out subjects, text, and layout. Keyword tags produce comma-separated phrases. Natural prose writes a flowing, precise description. Generic is a safe middle ground when you do not know the target model.

Question 5

How accurate is the description?

Accepted Answer

Very accurate for the visible content — the AI describes what it sees, not what it imagines, and will not invent details that are not in the image. Very abstract or ambiguous images get less useful prompts because there is less to describe. The Detailed level captures the most nuance.

Question 6

Can I get prompts in my own language?

Accepted Answer

Yes. Pick a language from the dropdown and the prompt is written in that language: English, Chinese, Japanese, Korean, Spanish, French, or German. Some image models respond best to English prompts, so English is a good choice even if you browse in another language.

Question 7

Will my uploaded images stay private?

Accepted Answer

Yes. Your uploads are stored in your private account workspace and are not shared with other users. The image is sent to our AI provider only to generate the prompt. You can delete any upload at any time.

Question 8

Does it work on non-photo images?

Accepted Answer

Yes — illustrations, 3D renders, pixel art, logos, and screenshots all work. It only struggles with intentionally abstract or extremely low-detail images, because there is little to describe. Try the Detailed level for unusual inputs to capture as much structure as possible.
