Show HN: Stickerbox, a kid-safe, AI-powered voice to sticker printer

https://stickerbox.com/
47•spydertennis•1mo ago
Bob and Arun here, creators of Stickerbox.

If AI were built for kids, what would it look like?

Asking that question led us to creativity, and more specifically, the power of kids’ imaginations. We wanted to let kids combine the power of their ideas with AI tools but we needed to make sure we did it safely and in the right way.

Enter Stickerbox, a voice powered sticker printer. By combining AI image generation with thermal sticker printing, we instantly turn kids' wildest ideas into real stickers they can color, stick, and share.

What surprised us most is how the “AI” disappears behind the magic of the device. The moment that consistently amazes kids is when the printer finishes and they are holding their own idea as a real sticker. A ghost on a skateboard, a dragon doing its taxes, their dog as a superhero, anything they can dream of, they can hold in their hand. Their reactions are what pushed us to keep building, even though hardware can be really hard.

Along the way the scope of the project grew more than we expected: navigating supply chains, sourcing safe BPA/BPS free thermal paper, passing safety testing for a children’s product, and designing an interface simple enough that a five year old can walk up and just talk to it. We also spent a lot of time thinking about kids’ data and privacy so that parents would feel comfortable having this in their home.

Stickerbox is our attempt to make modern AI kid-safe, playful, and tangible. We’d love to hear what you think!

P.S. If you’re interested in buying one for yourself or as a gift, use code FREE3PACK to get an extra free pack of paper refills.

smokeydoe•1mo ago
Looks really cool, but unfortunately I can not use it because thermal printing paper is coated with endocrine-disrupting chemicals like Bisphenol-A (BPA) or its substitute, Bisphenol-S (BPS), which can be absorbed through skin contact, potentially leading to metabolic, reproductive, or cancerous issues. It’s basically a very fine plastic dust. Though risk depends on exposure duration and amount, it’s not something I would feel comfortable with kids.

https://pmc.ncbi.nlm.nih.gov/articles/PMC5453537/

gingericha•1mo ago
The site claims to have BPA and BPS free printing paper
turkeyboi•1mo ago
Page claims “No-BPA and no-BPS printing paper”
loloquwowndueo•1mo ago
Did you miss the part where they explicitly said they did “ sourcing safe BPA/BPS free thermal paper” ?
dingnuts•1mo ago
I can't find the CPC certificate for this product. Children's toys are heavily regulated in the US and based on the thermal paper, the lack of display of their authorization to sell, the fly by night nature of a drop shipping website like this ...

I don't think this is a legal product to market towards children in the US

and that's without even mentioning the LLM usage

real glad my nibblings all got real art supplies when they were little. that fosters real creativity and the lot of them can draw better than any of the examples on the sales page, and they're still little kids. and there's no subscription, no EULA, their supplies are legal and safe to use, etc.

This product is actual trash

easton•1mo ago
don't mean to steal your customers, but can I just buy good thermal sticker paper somewhere that would work with a regular receipt printer? That would be fun for side nonsense, with or without AI.

When I was more youthful I remember getting the avery sticker sheets for a school election, but a roll where someone could do one at a time would be more useful for random stuff.

starkparker•1mo ago
500 BPA/BPS-free 4"x3" thermal labels for $16 or less: https://www.amazon.com/Thermal-Labels-Shipping-Multipurpose-...

Any of a variety of 4" thermal shipping label printers without AI, generally ranging from $30 to $75: https://www.amazon.com/Phomemo-Bluetooth-241BT-Wireless-Comp...

Everything about this is marked up to hell to pay for the generative AI end.

nickthegreek•1mo ago
I have a bluetooth thermal printer and the mobile app has this and other ai features available as a subscription option.
xnx•1mo ago
> We wanted to let kids combine the power of their ideas with AI tools

Why? Kids can combine the power of their ideas with crayons, markers, and pencils.

charcircuit•1mo ago
More options is better. I think it's possible for a niche to exist for AI creative tools like this.
tinfoilhatter•1mo ago
I'm struggling to find the creative part in having an AI print stickers for a child. Seems like the entire creative part is skipped over.
charcircuit•1mo ago
The amount of permutations of words you can say along with the permutations of drawings you can add to the sticker is a gigantic number. That is a big enough state space for people to express creativity.
venturecruelty•1mo ago
The entire point of being creative is that you actually MAKE it yourself, not that you tell the slop machine to make it for you. This is, quite frankly, the complete and total opposite of creativity. This is pure consumption disguised as creativity, wrapped up in a nice $99 box that will probably be e-waste in a couple years when the company goes under.
charcircuit•1mo ago
Is writing a book not creative if you use an existing font? There are both creative aspects like choosing words or choosing a font and non creative aspects like rendering the font.
venturecruelty•1mo ago
You and I both know this is a disingenuous argument. You're not saying "Hey, Stickerbox. Choose a nice font for me." You're saying: "Hey, Stickerbox, write the entire book for me."

Try again, please.

vrighter•1mo ago
it is not creative if all you did was choose a font.
lbrito•1mo ago
This is the best answer.

Although cool, I can see how this product will just inhibit instead of enabling creativity and play in kids. Instead of having to draw something to see it, refining the drawing over minutes or hours, the kid will just lazily ask for some half formed idea, and see it materialize from thin air. That's just sad

_rpxpx•1mo ago
Agree with all of that apart from "although cool". Why is it 'cool'? It's 'cool' only in the way Elon Musk and his retracting door handles are 'cool'.
add-sub-mul-div•1mo ago
Yeah. It's bad enough if kids prompting this stuff online is the new form that creativity is going to take. But this way, it's generating electronic crap that will end up in landfills as well.
SiempreViernes•1mo ago
Some kids might not have arms though? So this helps with that bit, but I'm not sure what they would do with the stickers.
tuckerman•1mo ago
I think with the right parental guidance/supervision this could be a very fun toy.

From the website it seems like a great way to generate some black and white outlines that kids can still color in. If used like that it seems almost strictly more creative than a coloring book, no? There are plenty of other ways kids can express creativity with pre-made art too. Maybe they use them to illustrate a story they dreamed up? Maybe they decorate something they built with them?

Also, some children might want to have fun be creative in ways that don't involve visual arts. I was never particularly interested in coloring or drawing and still believe myself to be a pretty creative individual. I don't think my parents buying me some stickers robbed me of any critical experience.

ghostpepper•1mo ago
Does a human review every sticker before it's ever shown to a child? If not, it's only a matter of time before the AI spits out something accidentally horrific.
jackb4040•1mo ago
I searched their site for any information on "how" they can claim it's safe for kids. This is what I could find: https://stickerbox.com/blogs/all/ai-for-kids-a-parent-s-guid...

> No internet open browsing or open chat features. > AI toys shouldn’t need to go online or talk to strangers to work. Offline AI keeps playtime private and focused on creativity.

> No recording or long-term data storage. > If it’s recording, it should be clear and temporary. Kids deserve creative freedom without hidden mics or mystery data trails.

> No eavesdropping or “always-on” listening > Devices designed for kids should never listen all the time. AI should wake up only when it’s invited to.

> Clear parental visibility and control. > Parents should easily see what the toy does, no confusing settings, no buried permissions.

> Built-in content filters and guardrails. > AI should automatically block or reword inappropriate prompts and make sure results stay age-appropriate and kind."

Obviously the thing users here know, and "kid-safe" product after product has proven, is that safety filters for LLMs are generally fake. Perhaps they can exist some day, but a breakthrough like that isn't gonna come from an application-layer startup like this. Trillion dollar companies have been trying and failing for years.

All the other guardrails are fine but basically pointless if your model has any social media data in its dataset.

InitialBP•1mo ago
I'm sure you are correct about being able to do some clever prompting or tricks to get it to print inappropriate stickers, but I believe in this case it may be OK.

If you consider a threat model where the threat is printing inappropriate stickers, who are the threat actors? Children who are attempting to circumvent the controls and print inappropriate stickers? If they already know about topics that they shouldn't be printing and are trying to get it to print, I think they probably don't truly _Need_ the guardrails at that point.

In the same way many small businesses don't (most likely can't even afford to) opt to put security controls in place that are only relevant to blocking nation state attackers, this device really only needs enough controls in place to prevent a child from accidentally getting an inappropriate output.

It's just a toy for kids to print stickers with, and as soon as the user is old enough to know or want to see more adult content they can just go get it on a computer.

jackb4040•1mo ago
ChatGPT allegedly has similar guardrails in place, and now has allegedly encouraged minors to commit self-harm. There is no threat actor, it's not a security issue. It's an unsolved, and as far as we know intrinsic problem with LLMs themselves.

The word "accidentally" is slippery, our understanding of how accidents can happen with software systems is not applicable to LLMs.

cube00•1mo ago
They fail their own checklist in that article.

> Here’s a parent checklist for safe AI play:

> [...] AI toys shouldn’t need to go online

From the FAQ:

> Can I use Stickerbox without Wi-Fi?

> You will need Wi-Fi or a hotspot connection to connect and generate new stickers.

nkrisc•1mo ago
> Stickerbox is our attempt to make modern AI kid-safe, playful, and tangible. We’d love to hear what you think!

How is it made to be "kid-safe"?

> Our model includes strict safety filters that block inappropriate content before it ever appears, ensuring that every creation stays fun, imaginative, and age-appropriate.

How do you filter the output of a generative AI like this?

hesdeadjim•1mo ago
I’m sure they just dump the image into another LLM to gauge “safety” and pretend it’s good enough.
SauntSolaire•1mo ago
Cynically, my guess is it's just through the system prompt.
threetonesun•1mo ago
Filter the input? If it's trained on all kid-friendly material and you have guardrails on the inputs what's going to come out. I believe Apple has done this pretty successfully on their image gen stuff that was clearly aimed at kids. Granted the outputs are... very boring, but they seem to never give back anything inappropriate.
nkrisc•1mo ago
Sure that’s plausible but is that what they actually do?
devmor•1mo ago
Wow, a product that exists entirely to deprive children of the ability to develop artistic creativity.

It's rare that I see a launch on HN that I could call abjectly evil, but this is certainly it.

GaryBluto•1mo ago
How dramatic. It's a little box that lets children make stickers by asking it, it's not "abjectly evil" in any sense.
venturecruelty•1mo ago
And asbestos just gives you a little cough. If I weren't already so cynical, this entire thread would certainly do it. You people are so goddamn dismissive in the most repulsive, condescending way.
GaryBluto•1mo ago
> You people are so goddamn dismissive in the most repulsive, condescending way.

If you can't handle seeing people disagree with you, why comment? Perhaps a place like Reddit or Mastodon would suit you better.

venturecruelty•1mo ago
I challenge you to re-read your comment again and again until you understand where you went wrong.
devmor•1mo ago
It’s a device specifically created to deprive children of creativity by doing all of the work their mind would do for them. The kind of process required for healthy childhood mental development.

It is heinously disgusting and morally repugnant, everyone involved with creating it and bringing it to market should be ashamed of themselves.

GaryBluto•1mo ago
You could've said the same about the first wooden toys putting an end to children having to use their imagination to make playing with sticks and pebbles fun, but you didn't, because what you grew up with gets a pass.
devmor•1mo ago
What on earth are you talking about? Toys do not create anything for children.
GaryBluto•1mo ago
You're arguing that the Stickerbox is bad because it spares children from using their imagination and I was saying that the first wooden toys did the same thing.

Every advancement has meant less thinking.

devmor•1mo ago
In what ways do you believe the first toys stop children from using their imagination? Essentially the entirety of developmental psychology agrees that inanimate toys are essential for developing imagination and fine motor skills. This is not something someone with experience in child development or safety would say.
nickthegreek•1mo ago
Is your issue with stickers robbing kids of creativity or do all the licensed IP stickers that fill the stores that children buy immune from this criticism?
devmor•1mo ago
That is a ridiculously dishonest comparison and you know it.
nickthegreek•1mo ago
No it’s not, and you know it. If a child wants dino stickers for something they are doing, I see no difference of them obtaining those stickers from Walmart or from a printer in their house. In both scenarios, the dinosaurs were not designed by the child. at least in the AI example they can customize to their wants. You don’t seem willing to thoughtfully engage in conversation. Why even post here in first place?
devmor•1mo ago
What is the difference between buying your child a dino sticker and buying them a machine that creates whatever stickers they want without having to think or look at anything, derived entirely from stolen artwork by others?

You might as well say there’s no difference between a rock and a semi truck.

You don’t seem willing to have an honest conversation, just assert ridiculous nonsense and call it a rebuttal - there is nothing thoughtful about your replies to me.

cobbzilla•1mo ago

Hey so I looked at your website and you say you're KidSafe COPPA certified, yet on their website it only mentions you as KidSafe listed? Any reason for the discrepancy?

https://www.kidsafeseal.com/certifiedproducts/stickerbox_dev...

Also, do you guys have CPSC CPC certificate? I couldn't find anything to that effect.

cube00•1mo ago
It's [...] not a place where kids can wander into unknown content.

When LLMs are involved, I don't find the guardrails as hard as they are making out.

If AI were built for kids, what would it look like?

Exactly like this and it's heartbreaking.

Lots of hate here, but I think this is clever and some iteration of it will sell well

I get that folks are worried about what AI-generated art will do to kids sense of creativity. Will they still learn to draw? Play instruments? Write stories?

But I genuinely believe that tech like this will only whet their imaginations. I would have had so much fun with this as an 8 year old, and would have spent hours just in my head, dreaming up ways to use my limited stickers.

Ofc parents will still need to encourage them to pick up hard skills (as has always been the case). But having an AI companion will mean they start seeing rewards for their efforts much faster. A shallower learning curve will prove to be a very good thing for most.

venturecruelty•1mo ago
Why learn to draw when the slop machine will make images for you? Why learn to write when the slop machine will make stories for you? Why learn an instrument when the slop machine will make music for you? This does nothing but kill actual creativity at the hands of the people making electricity expensive. We should be appalled and ashamed.

Also, criticism is not hate, and I think you and every other disingenuous AI cheerleader know it.

Wilder7977•1mo ago
These are all (both mine and yours) opinions, and we will need studies to see what's what. That said, my opinion is that not everything is a software development pipeline and needs to be efficient with short feedback loop.

To me what you say:

> will mean that they start seeing rewards for their efforts much faster

sounds essentially a negative. This leads to rewards-chasing and a habit of obtaining result without an appropriate amount of effort. This means that many won't even ever discover their passions or what they are good at. Putting the effort is a necessary step to grow. In other words, will any kid with this machine ever draw something from scratch, after they got used to having something much better than what they could do (at least at the beginning) by hand?

All of this without even mentioning the impact of creativity, where instead of having to think/conceive stuff you have a technology that does that for you after a minimal input, rehashing what has been already thought.

My wish is that tech people just realized that the world is better off without their tech in most cases and stopped thinking that everything in the world needs some tech to "help" (which of course is really a way to make money).

_rpxpx•1mo ago
Because kids famously hate drawing and using their imagination. How wonderful to have technology that can solve that ancient problem.
kyleee•1mo ago
More accurately - “probably kid-safe”
vrighter•1mo ago
so you built a tool to offload the creative part from kids. This is the total opposite of the stated goal. Using ai leads to brainrot
