Review

Summary

This lesson introduces Nano Banana as an AI image generator for creating and editing product art, especially for print-on-demand designs.

Core Idea

Nano Banana is useful because it follows natural-language instructions well and can revise images while keeping the overall design consistent.

Practical Value

Generate cartoon or realistic images
Edit images through plain-language prompts
Use reference images for style/concept direction
Create cross-niche product ideas
Access through Gemini or Google AI Studio
Compare subscription pricing vs pay-per-use API pricing

Access Options

Gemini

easier interface
useful for beginners
may include free trial
requires paid/pro access for best version

Google AI Studio

pay per image
better for occasional use
requires API billing setup
more technical
allows control over settings like aspect ratio and resolution

Workflow

Generate base image
Ask for edits
Download image
Upscale if needed
Remove background in Canva/other editor
Turn into POD-ready file

Important Limitation

Nano Banana may not create true transparent backgrounds.

Best workaround:

generate on plain white or black background
remove background later in Canva or another editor

Cost Logic

If using Google AI Studio:

each image costs a small amount
edits also cost money
repeated revisions increase cost

If generating many images monthly:

subscription may be cheaper

If generating only a few:

pay-per-use may be cheaper

Cost Comparison Checklist `[0/4]`

Estimate number of images needed per month
Include revisions/edits in estimate
Compare total API cost to subscription cost
Choose cheaper option for current workload

Image Generation Checklist `[0/7]`

Choose target product/design purpose
Write clear prompt
Specify style (cartoon, doodle, realistic, etc.)
Specify background color
Review output
Request edits if needed
Download final image

POD Preparation Checklist `[0/6]`

Upscale image if needed
Remove background
Add/edit text in Canva or design app
Export as PNG
Use transparent background
Test on product mockup

Warnings

Free versions may include watermarks
Pricing and access may change
API use can add up with many revisions
Do not assume generated backgrounds are actually transparent
Always check image quality before printing
Do not copy reference designs too closely

Key Insight

The tool is strongest when used interactively.

Prompt → review → edit → refine

This is better than expecting one perfect image from one prompt.

My Take

Nano Banana is useful as an art-generation and editing tool, but it is not the full production workflow.

You still need:

human product judgment
background cleanup
upscaling
layout work
POD export preparation

Bottom Line

Use Nano Banana to quickly create and revise design assets.

Then use Canva or another editor to turn those assets into clean, print-ready product files.

00:00
Hey, everyone. So this here is,

00:03
1 of my favorite

00:04
AI image generators right now, Nano Banana. I have been

00:07
increasingly using Nano Banana more and more. I still use

00:11
multiple

00:12
AI image generators.

00:14
Currently, I've got Nanobanana that I'm using. I'm using Midjourney.

00:18
I'm using ChatGPT's

00:19
image generator.

00:20
And should any more image generators come out that are

00:24
excellent, I'm sure I will pick them up as well.

00:26
But Nanobanana

00:27
is currently, right now, probably the 1 I go to

00:30
the most.

00:31
So this is Google's AI image generator,

00:35
and, there are actually 2 versions of it. So there

00:38
is a pro version and there is a free version.

00:42
The pro version is what I use. I use the

00:45
pro version for 2 reasons. Number 1, the free version

00:48
comes with,

00:49
a watermark,

00:50
whereas any images made on the pro version currently do

00:53
not have a watermark.

00:54
And secondly, the images are just better. And 1 of

00:58
the things about Nitto Banana that is so nice is

01:00
that it's not just about the fact that it creates

01:04
great images.

01:05
It's about the fact that

01:07
you can,

01:08
have a lot more control

01:10
over what you create with it because it's got such

01:14
great natural language learning capabilities,

01:17
built into it,

01:18
and also because of the fact that it's very, very

01:22
good at following instructions.

01:24
That's been the really cool thing about Deno Banana is

01:27
that it's brought in a new era of AI image

01:30
generators that are very, very good at staying consistent,

01:33
both with following your instructions and also

01:37
with consistency

01:38
just across images in general. And the other AI image

01:41
generators have copied of Nuna Banana's,

01:45
you know, revolution in that regard.

01:47
But it was the first to truly get it right.

01:50
And plus, it's also extremely good with text as well.

01:53
Now

01:54
there are 2 ways that you can access Nano Banana.

01:57
The first is through Gemini,

01:59
which is Google's own version of ChatGPT.

02:03
And the second version is through the Google AI Studio.

02:07
Now,

02:08
these are quite different ways to, to access it.

02:12
So for reference,

02:14
if you access it through Gemini,

02:17
Google's version of Chat GPT,

02:19
you will need to have the pro version of Gemini.

02:23
And currently, right now, you can get access to a,

02:27
a subscription for the pro version

02:29
for free for 1 month. So normally it costs 20

02:32
US dollars a month for a subscription,

02:34
and that gets you access to all of their pro

02:37
features.

02:38
And to be fair, these are fantastic features as well

02:41
in their own right.

02:43
But

02:43
in addition to all this, you get access to the

02:45
pro version of Nano Banana.

02:48
And so for many people, at least to start with,

02:51
this is probably what they will do. They will go

02:54
ahead, get Nano Banana

02:56
through or they'll access, they'll get a free Gemini Pro

02:59
subscription. And then when you're in here, you can come

03:01
and you can click create an image. So you can

03:03
do it that way, or you can come here to

03:05
tools, and you can click to create an image.

03:09
So So this is 1 way to access Standard Banana.

03:11
The second way to access it, of course, is through

03:13
the Google AI Studio.

03:16
Now the thing about the Google AI Studio is that

03:18
it's not free. You actually need to connect a credit

03:21
card through setting up an API key, which is very

03:23
bit very easy to do. You can just follow the

03:26
on screen instructions to do it.

03:29
You just need to basically add your credit card in

03:31
through the form of an API

03:33
key, and then you pay

03:35
per image that you generate.

03:38
Now as I'll show you, each image that you generate

03:42
generally costs a few cents.

03:44
So when you think about it,

03:47
initially, you might start out using Nano Banana through Gemini

03:51
because the fact that you can access it for free.

03:53
And if you have good reason to want to stay

03:55
subscribed to the pro version, I'm I'm subscribed to the

03:58
ultra version. So I love Gemini

04:01
as a tool. I think it's very great, very helpful.

04:04
It's been a huge

04:06
improvement for my life even. I use Gemini to help

04:09
me,

04:10
do market research recently when buying some property,

04:13
and I used the ultra,

04:17
AI version of Deep Research. So

04:20
I love Gemini,

04:22
but you might not find that there's a reason to

04:24
stay subscribed to Gemini

04:26
Pro,

04:28
outside of, Netter Banana. If so, then it will make

04:32
more sense for you in the future to switch

04:35
to the Google AI Studio because then you can just

04:38
generate each image that you need and pay a few

04:40
cents.

04:41
So in this tutorial, I'm gonna take you through both.

04:46
We're gonna go ahead and we're gonna start out on

04:49
the Gemini app, and then I'll show you how to

04:53
use

04:54
the Google AI Studio.

04:56
Alright. Let's start out then with Gemini.

04:59
So, of course, as I mentioned before, within Gemini, if

05:02
you want to access Nanobanana,

05:04
you come to the tools and you select create an

05:06
image, or if the tools are available down there for

05:08
you, you can select it too.

05:11
Now there are 2 main ways that you'll generally create

05:14
an image with Nano Banana.

05:16
The first is just simply asking it to create an

05:19
image for you, and it is really, really great at

05:24
doing that. So let's try creating something now.

05:27
Let's create

05:30
a cartoon

05:32
doodle

05:33
of

05:34
a husky,

05:37
white background.

05:42
And I'm filming this all in real time, by the

05:44
way, so that you can see generally how long it

05:47
takes to work. Because when you try to create

05:50
designs at scale, to upload, to create products at scale,

05:54
it's actually quite useful to know how many seconds a

05:57
tool takes, particularly when you start stacking tools on top

06:00
of each other. If 1 tool takes 1 minute and

06:03
then another tool, you're using another, like, 5 other tools

06:05
and they take a minute, then you can calculate how

06:08
many designs effectively you can create per hour.

06:11
Alright. So here is the little doodle that it made

06:14
for us.

06:15
So we could now go in and ask for some

06:17
changes. So we could say,

06:20
can you color the husky?

06:28
In the past,

06:30
it was so much harder to make these sorts of

06:32
changes.

06:34
But now it's so easy

06:36
that we can just be using a chatbot like this.

06:40
So

06:41
I definitely personally currently prefer to be generating images in

06:44
this way,

06:45
just having a natural learning.

06:48
And and yep.

06:50
Sorry. Natural,

06:51
language learning experience with it.

06:54
Here I see. Now it's colored it for us just

06:56
like that. Let's say I wanted to,

06:59
remove the collar.

07:02
Can you remove the collar?

07:13
And so now it's gonna go ahead, and it's gonna

07:15
remove that collar for us.

07:17
And it's going to fill in the difference with the

07:20
husky

07:22
and just show, the husky's fur.

07:37
Look at that.

07:38
We no longer have a collar on our cute little

07:41
husky.

07:43
So it's actually super easy to come in here and

07:45
edit these images.

07:47
You just ask for specifically what you want.

07:50
So if you want to download an image, you can

07:53
also just come and click to download the image in

07:55
full size. And the pro version does have high resolution

07:59
images,

08:01
but I would still recommend that you

08:04
increase the resolution,

08:06
and try making as high as possible. So if you're

08:08
going ahead and editing these images within Canva like I

08:11
do, then I would still use the upscaler tool to

08:14
upscale images.

08:18
So that is 1 way to be able to create

08:21
images, just simply working with it and getting it to

08:23
create what you want.

08:25
And just for reference, it's also extremely good at creating

08:29
realistic

08:30
pictures as well, not just cartoons.

08:33
So

08:35
create a photo of

08:47
and something that I think is quite remarkable when you

08:49
compare it to earlier versions of AI art generators,

08:53
such as Chechi Petit's earlier AI image generator, is that

08:56
back in the day, if you had asked it to

08:59
make a change to the husky and you'd asked it

09:01
to remove the collar,

09:02
it would have redrawn the entire image, and the image

09:05
would not have looked identical.

09:08
So

09:10
here we go.

09:12
As you can see, it looks scarily realistic.

09:15
So you can indeed make realistic images too with Nano

09:19
Banana, not just cartoon style images.

09:23
So let's try a different way, though. So another way

09:26
that you can create images is you can use reference

09:29
images,

09:30
and reference images can be extremely

09:32
helpful.

09:34
So

09:35
here is

09:36
a picture of a t shirt which,

09:39
has done well over the Christmas period,

09:42
this

09:43
year. 6 7, if you don't know what it is,

09:45
is an Internet meme, and it's an Internet meme that's

09:48
popular with gen alpha

09:50
and in to a lesser extent, I think, gen z.

09:53
So depending upon which, generation bracket you're in, you may

09:57
have not heard about it.

09:59
Either way, it's an Internet meme, and,

10:02
the meme involves both 6 7, and there's also, like,

10:06
a little hand gesture. It relates to a viral video.

10:10
So somebody came and took this meme

10:13
and made it Christmas themed, and it was popular. You

10:16
know? It's gotten,

10:18
it's gotten over 4000 views. It was over 4000 sales

10:22
in the past month.

10:23
And on Amazon,

10:26
they will have, sales brackets. So it'll say 4000 plus

10:30
sales in the past month or 5000 plus sales in

10:32
the past month. So we know that this has sold

10:34
anywhere from 4000 sales to 4999

10:38
sales. Although even if it had only sold 4000 sales,

10:41
that's a lot of t shirts.

10:44
So something that you can do is you can find

10:46
popular designs online

10:48
and then you can repurpose them.

10:52
And

10:55
Nanobanana is fantastic at this. So

11:00
I took some examples of t shirts. There was another

11:03
more generic 6 7 t shirt that had done well,

11:06
which the Christmas 1 was based off of. So taking

11:09
some screenshots here of these shirts.

11:14
I like

11:16
this concept

11:18
for a t shirt,

11:20
but I would like it to be

11:24
Halloween

11:25
themed.

11:26
Can you make for me

11:29
a Halloween

11:30
themed

11:32
6 7 t shirt with the meme hand

11:37
gesture?

11:38
Oops.

11:40
Here we go.

11:46
And so now we're targeting an entirely

11:48
different

11:50
customer base

11:51
because we're targeting people who are interested in Halloween themed

11:56
shirts. So this is a good example of a cross

11:59
formula idea

12:00
where we take a popular T shirt format,

12:04
and then we cross it together with an entirely different

12:06
niche to create something very new that's targeting a different

12:09
customer base so that we're not,

12:13
just trying to take sales away by copying the preexisting

12:16
design, but we're reaching an entirely different customer base.

12:21
So here we go. Be like,

12:25
remove the

12:27
text and remove the glow effect.

12:38
You can also,

12:41
when it when it starts to think, you can go

12:43
ahead and you can see it's thinking as well, which

12:45
is quite interesting. If you're a little bit nerdy like

12:48
me and you like to see how it's, how it

12:51
works.

12:53
You can just click this,

12:56
and then you'll be able to see,

12:58
what's actually going on under the surface

13:02
as it's working.

13:04
And here it is.

13:06
And look, it did an excellent job,

13:09
of, following my instructions here. Of course, it's on this

13:13
T shirt, which we don't want.

13:15
I just want the design

13:18
on a

13:19
plain

13:20
black

13:22
background,

13:23
not a T shirt.

13:31
And so now it'll come in,

13:34
and it will remove the T shirt portion of this

13:37
design,

13:39
and it will just draw it straight onto a plain

13:42
background

13:45
for us. And the reason why I pick a black

13:48
background

13:49
is just because it will be easy to remove it

13:52
with a background remover in, say, Canva.

13:55
Currently, within Nano Banana, you cannot

13:58
create images on a transparent background. That might change in

14:01
the future depending upon when you were watching this. They

14:03
may have added it. Right now, you cannot put images

14:06
onto a transparent background.

14:08
It'll show the transparent. It'll make it look transparent, but

14:11
it won't actually be transparent, but it will mimic the

14:13
the little squares that you see.

14:16
It's not actually transparent. So currently,

14:18
the easiest way to remove a background

14:21
of an image you make with it is to put

14:23
it onto a plain background

14:25
and to then use a background remover to get rid

14:28
of it.

14:32
And here we go. It has done this for us.

14:35
So now we could download this and then pop it

14:38
into,

14:40
a program like Canva

14:42
and then edit it and turn it into a t

14:45
shirt design that is suitable for us.

14:47
So

14:48
this is 1 way to access,

14:51
Nanobanana

14:52
through Gemini. However, as I said,

14:55
while it will be the cheapest way initially to start

14:57
with most likely because of the fact that they're currently

14:59
giving away a free 1 month trial,

15:03
depending upon whether

15:05
you have access to that trial, depending on it, like,

15:07
it might be that by the time you're watching this,

15:09
the trial is no longer being offered.

15:12
Or it may be that you've already had your 1

15:14
month trial, and,

15:17
you would now have to pay 20 dollars a month

15:19
for it. You may not need to keep your access

15:21
to Gemini Pro.

15:23
So in which case, it could be better for you

15:25
to switch to the Google AI Studio,

15:27
and I will show you how to use that right

15:29
now. Alright. Here is the Google AI Studio. So as

15:33
I said, this is a different way that you can

15:35
access Nano Banana.

15:37
So to access the Google AI Studio,

15:40
the URL is literally just a I studio dot Google

15:43
dot com. And, of course, you can always Google it,

15:47
and you'll be able to access it there. The Google

15:50
AI Studio

15:51
is mostly aimed at professionals

15:54
because the interesting thing is that with Gemini, if you're

15:58
accessing Google's AI tools through Gemini, you have limited access,

16:01
particularly

16:02
for things like, say,

16:04
the Yo 3, which is their,

16:07
video generator. With those, you have daily limits. And there

16:10
are also daily limits, for how much you can use

16:13
Nano Banana as well, but you're unlikely to hit them.

16:16
So

16:18
with the Google AI Studio, you can have unlimited access

16:21
to their tools

16:22
because instead of having 1 subscription giving you access to

16:26
a bunch of,

16:29
your,

16:30
data that's a sort of preset preset limits. With the

16:33
Google AI Studio, it's unlimited and you pay per usage.

16:37
So the Gemini

16:39
subscription is great value if you utilize all of your

16:42
limits.

16:43
But

16:44
if you are only using a small amount, you actually

16:47
can save a lot of money by just generating your

16:50
images through the Google AI studio.

16:52
So it's entirely up to you, but this is a

16:55
great hack to know about because it might save you

16:57
money.

16:59
So

16:59
inside of here, you've got 2 different ways currently to

17:03
access Nano Banana.

17:04
If it's here available on the what's new, you can

17:06
click that, but it's probably not always gonna be new.

17:09
So if you come to the playground,

17:11
then you can come up here and you can choose,

17:14
which tool you want to use. We want to use

17:17
Nano Banana Pro.

17:19
Now using Nano Banana

17:21
Pro is very, very similar to how it is within

17:24
Gemini.

17:24
1 change is that

17:26
over on the side here, you can make some direct

17:29
you you can set some settings up immediately. So for

17:32
example, you can change your aspect ratio,

17:34
and you can change your resolution.

17:36
Now changing a resolution

17:38
will increase how much the toke how many tokens get

17:41
used. Tokens are how they calculate how much how expensive

17:45
an image is and how much it's gonna cost you.

17:48
The more tokens your, image uses,

17:51
the more expensive it's gonna be. So you probably wanna

17:53
keep this at 1 k resolution because we can increase

17:57
the resolution

17:58
within Canva. And chances are you're probably going to want

18:01
to be you to using Canva to turn your image

18:04
into a print ready file anyway

18:07
or some other graphic design app. And,

18:10
Canva has an AI upscaler included within it.

18:14
So

18:15
I would keep it at the lowest resolution to save

18:18
money.

18:19
And then we come here for the prompt, and it's

18:21
it's the same thing.

18:22
Let's just see. We want a

18:25
draw

18:26
a doodle

18:27
of a

18:29
husky on a white

18:31
background.

18:42
So you can see here it says that I've got

18:44
a paid API key.

18:46
So you can come and click here to add in

18:48
an API key. You can follow the instructions,

18:51
but love to show you how to do it. Unfortunately,

18:54
there's a lot of secure credit card data there, which

18:57
is too hard for me to hide. So I can't

19:00
show you how to set up an API key, but

19:02
it is quite similar.

19:04
And here it is.

19:05
I'm actually not super fond with this.

19:09
But,

19:10
either way, it would be very easy to go back

19:13
to

19:14
and get it to change it. Of course, every time

19:16
you ask it to change it within the Google AI

19:18
studio, it uses more tokens. You can see we've so

19:21
far used 529

19:22
tokens, and I'll

19:24
calculate later on how much this has cost me. It's

19:27
only cost me. Like, we're talking cents here. This is

19:30
not dollars. This is cents.

19:34
Remove the icons

19:37
around that husky

19:39
and make the

19:42
well, I guess it's got the eyes because of the

19:43
fact that some of the huskies have, different colored eyes.

19:47
So that's not so bad. But the

19:49
but I'll still go and make the eyes

19:54
the same.

20:02
We'll just get it to do that to see if

20:03
we can

20:05
see what it would be like if it did it

20:08
as an experiment.

20:16
And you can also come and

20:18
view the,

20:19
thinking as well, which is always very interesting.

20:25
Look. It did it.

20:26
So it made the eyes the same type of, same

20:30
sort of, like, same eye style,

20:32
and it got rid of the

20:34
got it got rid of the,

20:36
the icons around it. So you can see, though, that

20:39
it's definitely increased our usage. We've basically doubled the tokens

20:42
that we've used before. Again,

20:44
we will calculate that later.

20:46
So here we are inside of Gemini API pricing, and

20:49
we can see here that currently,

20:51
it is 0.134

20:54
dollars, so 13.4

20:57
cents,

20:58
per image because of the fact that it is 12

21:01
dollars per 1000000 tokens. And generally speaking, an image works

21:05
out to be about 1000 tokens. So that means then

21:08
that you're paying about 13.4

21:10
US cents

21:11
per image. Now

21:13
this is where you need to do the math because

21:15
you think about it. A Gemini Pro subscription

21:19
costs 20 dollars.

21:22
So if you want it to,

21:25
see if it's cheaper or not for you to be

21:28
using the API studio,

21:30
then what you wanna do is you wanna divide this

21:34
by

21:36
the cost of each image,

21:38
and it comes out to 149

21:41
images.

21:42
Now it's actually quite easy to generate more than 149

21:45
images. It is very easy to generate

21:48
150

21:48
plus images, but it depends upon how much time you

21:51
have and how quickly you are growing and scaling

21:54
your your store and your business.

21:56
So if you're creating a lot of images,

21:59
then you,

22:01
will

22:02
want to probably switch to the Gemini Pro account because

22:06
then you'd have access to a lot more images,

22:09
especially if you want to then access any of the

22:11
other benefits of Gemini Pro because you get free storage

22:13
with Gemini Pro, free cloud storage, and you get access

22:17
to VEO 3, their, video generator.

22:20
So if you and also, yeah, but you you get

22:23
greater access to their chatbot as well, and,

22:27
you can access,

22:29
that at higher rates. So

22:32
if that makes sense for you, then you can totally

22:34
do that. But if you think that currently right now,

22:36
you're not able to spend a lot of time on

22:38
your business and you're only adding a few products a

22:40
month, then you could end up saving quite a bit

22:43
of money if you just

22:45
generate each image individually.

22:48
But, yes, that is how to use,

22:50
Nanobanana.

22:52
I hope that, you find it as helpful,

22:56
as I have.
