Nano Banana AI

Many image models are good at making something new. Nano Banana is also good at changing something that already exists. When you give it a reference photo and a clear instruction, it tends to change only what you asked for and leave the rest alone, including faces. That is why it became popular for edits like "put this person in a rainy Tokyo street" or "turn this photo into a figurine on a desk".

Typical things it does well:

• Targeted edits: "make the car red", "remove the lamp on the left", "change the sky to sunset".
• Same subject, new context: keep a person, pet or product and change the scene around it.
• Style transfer: redraw a photo in a given art style while keeping the composition.
• Plain text to image: clean, realistic images from a prompt alone.

For a simpler, cheaper edit at $0.03, the AI Image Editor uses a different fast editing model. For higher resolution, Nano Banana Pro (2K) is available in the AI Image Generator for $0.40.

Nano Banana is also the engine behind several focused RegiAI tools that wrap it in a simple form, such as the AI Head Swap, AI Dress Changer and AI Body Swap. Use those when your task matches, and this page when you want to write your own instruction.

• Be direct: write edits as instructions. "Replace the background with a snowy forest" works better than "snowy forest".
• Say what must stay: "keep his face, clothes and pose the same" helps when you only want the scene to change.
• One reference, one idea: this page accepts one reference image. For combined edits, run them in steps and use each result as the next reference.
• Describe light and style: "soft studio light", "35mm film photo" or "Pixar-style 3D" steer the look.
• Keep prompts focused: a single clear request usually beats a long list of changes in one generation.
• Use a clear reference: a sharp, well-lit photo gives a sharper result. If yours is blurry, run it through Unblur Image first.

Only upload photos of people who have agreed to it, and never use edits to deceive, harass or impersonate anyone.

Example prompts to try with a reference photo: "put this person on a sunny rooftop in Lisbon, keep the face and outfit"; "turn this photo into a hand-painted watercolor"; "make this product look like it is on a marble kitchen counter with morning light"; "turn this dog into a plush toy sitting on a bed". Without a reference: "a cozy reading nook with a window seat on a rainy afternoon, photograph".

Every generation costs $0.10, with or without a reference photo. RegiAI has no subscription; you buy credit packs ($10, $25, $50 or $100, the larger ones with bonus credit) and pay per use. Because the price is $0.10, the one free generation per day that every signed-in user gets can be used here. It does not stack or roll over. If a generation fails, the charge is refunded automatically.

Results have no RegiAI watermark and are saved as JPG in My creations in your dashboard for 30 days. You can download or delete them there.

If you use Nano Banana often, compare it with the other options on RegiAI. FLUX Schnell in the AI Image Generator costs $0.01 per image and is handy for drafts. The AI Image Editor costs $0.03 per edit for simple changes. Nano Banana at $0.10 is the one to reach for when you need careful edits that keep a person or product looking the same.
