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

https://stickerbox.com/
24•spydertennis•2h 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.

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.

Did you miss the part where they explicitly said they did “ sourcing safe BPA/BPS free thermal paper” ?
dingnuts•59m 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•1h 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.

> 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•1h ago
More options is better. I think it's possible for a niche to exist for AI creative tools like this.
tinfoilhatter•8m 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.
lbrito•55m 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•35m 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'.
ghostpepper•1h 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•1h 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•44m 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.

> AI toys shouldn’t need to go online or talk to strangers to work.

Interesting 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•1h 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•58m ago
I’m sure they just dump the image into another LLM to gauge “safety” and pretend it’s good enough.
SauntSolaire•55m ago
Cynically, my guess is it's just through the system prompt.
threetonesun•5m 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.
devmor•52m 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.

cobbzilla•44m ago
wow the haters are out today! Happy Holidays All! Congratulations to Bob & Arun on the launch!
smallerfish•23m ago
The biggest problem is that when this company goes out of business in 5 years that it'll become a paperweight.

I'm still bitter at Logitech for screwing up Squeezebox.

strongpigeon•16m 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•15m 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.

maniacwhat•9m ago
When Google and OpenAI struggle to filter their own models to be age appropriate, what makes you think you have been able to crack the problem?
mh-•5m ago
Congrats on the launch.

Make sure your materials safety/CPC stuff is done correctly (see other comments [0].) For the content safety concerns, I assume you're using OpenAI's Moderation endpoint (or similar). If not, you need to be.

Assuming you've got those solved: I could see this being something that's rented out for parties the way people do with photo booths. Imagine having Stickerbox on a media cart with a battery and rolling it around a children's hospital floor.

Pursuing either of those avenues will (rightly) require you have both of the concerns I listed solved, of course.
